Abstract

Thiamine hydrochloride (VB1) is found to be an inexpensive, efficient, non-toxic and mild

catalyst for the cyclocondensation of o-phenylinediamine and

aromatic/heteroaromatic/aliphatic aldehydes in water at moderate temperature. The present

work contributes a greener approach for the synthesis of benzimidazole derivatives under

gracious (water) reaction medium which resulted into facile, sustainable and high yielding

methodology.

Keywords: benzimidazoles, sustainable chemistry, thiamine hydrochloride (VB1), water

INTRODUCTION

In this day and age an embryonic

awareness of the environmental

consequences of the chemical output and

protocol by which they are produced has

led to the gentle concept of “Sustainable

(Green) Chemistry.” Green Chemistry has

emerged as an important aspect of all

chemistry that reduce or eliminate the use

and generation of hazardous substances in

the design, manufacture and application of

chemical products.[1]

In a sustainable

civilization, manufacturing processes are

designed in such a way so as not to

generate waste products, else they are put

for recycling/biodegrading.[2]

Green

chemistry has produced itself the landlord

of organic chemistry, since it’s

fundamental scientific methodologies can

protect human health and the environment

in an economically beneficial manner.[3]

Therefore, there has been great expedition

towards the improvement of greener

chemical processes. The present research

involves the use of natural solvent i.e.,

“Water” that can be surrogates for organic

solvents. Water could be dedicated solvent

under reflux temperature of reaction

condition for organic transformations,

because it is readily available, highly

polar, nonflammable, nontoxic, cheap, and

could offer the easy separation of reagents

or catalysts from many organic products.[4]

Several organic transformation has been

performed by using water as a solvent.[5]

Considering the above worthwhile

advantages of water as competent

reactions medium herein, attempt has been

made to perform the cyclocondensation of

o-phenylinediamine and

aromatic/heteroaromatic/aliphatic

aldehydes catalyzed by VB1 in water for

obtaining the desired benzimidazoles.

In the last few decades benzimidazoles

have been much utilized for the synthesis

of diverse highly functionalized molecules

because of their broad spectrum of

biological/pharmacological activities.[6]

It

has been observed that numerous

benzimidazole derivatives are successfully

Redox System Initiated Improved Low-Temperature

Colouration of Real Silk With Metal-Complex Dyes for

Energy Conservation

Bipin J. Agrawal* Department of Textile Chemistry, Faculty of Technology and Engineering,

The Maharaja Sayajirao University of Baroda, Vadodara, Gujarat, India

Abstract

Silk has always been the symbol of royalty due to its lustrous appearance and peach like

softness. It can be dyed in bright shades with the available natural and many synthetic

dyestuffs. The slight cationic character of silk makes it possible to be dyed with anionic

synthetic dyes such as acid, metal complex, reactive and selected direct dyes. The main

objective of colouration of a textile fibre should be to maintain the permanency of the colour

and not allow any damage of the fibre. However, conventional dyeing of silk by exhaust

dyeing method with these dyes is usually performed at near boiling temperature, which

substantially damages the silk fibre, loses its magnificent luster and deteriorates its qualities.

Many approaches have been adopted to decrease this potential damage of silk fibre. One

such effort is redox system initiated low temperature dyeing of silk substrate to preserve its

aesthetic characteristics. The redox system is formulated by the utilization of glucose and

hydrogen peroxide as reducing agent and oxidizing agent respectively. The dyeing of silk

substrate is performed with metal-complex dyes at low-temperatures and compared with the

conventional exhaust dyeing performed at 90°C. Conventionally, an ionic bond is formed

between the silk fibre and the anionic dye(s) when the dyeing is performed at or near boil.

However, the redox system has aided a much strong covalent bond formation between the

metal-complex dyestuff and the silk substrate at much lower temperatures than the

conventional dyeing temperature. The dyeing performance has been evaluated

spectrophotmetrically in terms of colour strength (K/S) values and the results are compared

with the conventionally dyed samples. Fastness characteristics (wash, light and rub, both wet

and dry) of various dyed samples are also evaluated and compared with each other.

Keywords: Mulberry silk, metal-complex dyes, exhaust dyeing, redox system, free-radical

INTRODUCTION

The dyeing process is one of the most

significant parts of textile wet processing

that utilizes huge amounts of energy.

Generally, dyeing involves adsorption of

molecules or ions of the dye onto surface

of the fibre from solution phase (i.e.,

dyebath). This is followed by diffusion of

the adsorbed molecules into the fibre.

These processes are influenced by factors

such as pH, temperature, concentration of

dye, presence of other dyeing agents,

liquor ratio, etc. Temperature plays a key

role in the economics of the dyeing

process. Main objective of a successful

dyer is to reduce the temperature of dyeing

so as to conserve energy. Attempts have

been made to reduce the energy

Abstract

Owing to the stringent environmental regulations in many countries for production of ultra-

low sulfur petroleum fractions with the aim to reduce sulfur emissions, has resulted in

increased interest in this area among the scientific community. The need for zero sulfur

emissions enhances the requirement of more advanced techniques in desulfurization. The

mechanism of desulfurization by extraction is a promising approach having several

advantages over the conventional method of hydrodesulphurization. The data and results

provided in the present paper explore the significant insights of phosphonium based ionic

liquids as a promising environmentally benign solvent for the extractive desulfurization of

liquid fuel.

Keywords: Ionic Liquids, Desulfurization, Liquid Fuel, Extraction, Industrial Application

INTRODUCTION

The development of efficient deep

desulfurization processes for diesel fuel

has been challenging work for chemists,

since pollution caused by exhaust

emissions (especially SOx) is one of the

most serious environmental problems in

the world. For environmental protection

purposes, many countries have mandated

reduction of the S-level in fuels down to

10 ppm by 2016, and the trend is to

achieve sulfur free fuels in the following

years. In India, the present norms have

been decided by the Central Pollution

Control Board, and currently the total

sulfur content in liquid fuels is limited to

350 ppm although it should be reduced to

as low as possible. In the petroleum

refining industry, the hydrodesulfurization

(HDS) processes, which has been

employed to remove organic sulfur from

fuels for several decades, needs high

temperature and pressure, large reactor

volumes, and very active catalysts. Owing

to continuous fuel quality challenges,

basic scientific research has started in the

field of extraction of sulfur compounds

with ILs, which have shown potential in

alternative and future complementary

technologies for deep desulfurization.

Subsequently, technologies such as

extractive desulfurization (EDS), selective

adsorption, catalytic oxidation, and

biodesulfurization have been applied.

Compounds such as ethers, amines,

alcohols and other volatile organic

solvents have been used for absorption,

extraction, azeotropic distillation, and

many other methods. Conventional

solvents have their own limitations on

account of environmental issues,

recyclability etc., which can be overcome

by the use of ILs as green solvents.

Phytoremediation: Its Background and Global Scenario

Chhavi Jain*

MM College, Modinagar, Uttar Pradesh, India

BACKGROUND

Phytoremediation is an evolving in situ

remediation technology that utilizes plants

to clean polluted soil, groundwater and

wastewater. Phytoremediation is defined

as that branch of science that utilizes

inherent abilities of green plants to

remove, contain, or render harmless

environmental contaminants such as heavy

metals, metalloids, organic compounds,

trace elements, and radioactive substances

present in soil or water. The plants used in

this technology include trees, shrubs,

grasses and even aquatic plants. The idea

of using plants for cleaning up of

contaminated soil and water is not new. It

was around 300 years ago, when plants

were proposed to treat wastewater.[1]

Thlaspi caerulescens and Viola

calaminaria were the first plant species

reported to accumulate high level of

metals in their leaves.[2]

Afterwards, other

plants such as those from the genus

Astragalus, were also reported of

accumulating metals like nickel and

selenium in their shoots.[3, 4]

The idea of using plants to absorb metals

from polluted soils was developed and

reintroduced by Utsunamyia and

Chaney.[5]

The first field trial of this

concept was conducted in 1991 for

phytoextraction of zinc and cadmium.[6]

Since then, extensive research is being

carried out to investigate the biology of

this metal phytoextraction. Although

significant success has been achieved in

this regard, our understanding of plant

mechanisms that enable them to carry out

this remediation process is still emerging.

Land and water pollution due to heavy

metals is a worldwide issue.[7]

Nearly, all

countries have been affected by heavy

metal pollution, though the area and

severity of such pollution vary immensely.

This has led to an increasing concern with

regard to accumulation of heavy metals in

environment as they pose big threat to both

human health and natural environment.[8]

In this regard, the science of

phytoremediation has shown promising

results as an innovative cleanup

technology.

GLOBAL SCENARIO

Phytoremediation research is going on in

every continent, but most of the work is

carried out in US, Africa and Asia. In US,

funding agencies viz., Environmental

Protection Agency (EPA) and the

Department of Defence (DOD) encourages

applicative research that focuses on

everyday contamination scenarios. This

has resulted in relative success of

commercial phytoremediation, as

entrepreneurial businesses attached to

research institutes. There are a number of

conventional remediation technologies

which are employed to remediate

environmental contamination with heavy

metals such as solidification, soil washing

and permeable barriers. But a majority of

these technologies are costly to implement

and cause further disturbance to the

already damaged environment.

Phytoremediation is evolving as a cost-

effective alternative to high-energy, high-

cost conventional methods. It is considered

to be a “Green Revolution” in the field of

innovative cleanup technologies.

Phytoremediation has the potential to clean

an estimated 30,000 contaminated waste

sites throughout the US according to the

EPA’s Comprehensive Environmental

Soil Moisture Level and Carbon Release Are Inversely

Proportional: Recent Report

Meenakshi Tripathi*

Department of Botany, Lucknow University, Lucknow, Uttar Pradesh, India

With the advancements in the field of

science and technology, it is now possible

to predict or control climatic changes. A

recent scientific research shows that the

soil moisture levels can help determine the

amount of carbon that is released into the

atmosphere.

An international team led by Northern

Arizona University scientists investigated

the results of 25 experiments carried by

multiple research groups including the

Department of Energy's Oak Ridge

National Laboratory.

These scientists studied the emission of

greenhouse gases from incubated soil

samples in the field sites of Alaska,

Canada and Russia, under a temperature

increase of 10° C.

It was found that soils with plenty of

oxygen from air released about 3.4 times

more carbon than wetter soils with limited

oxygen. Even accounting for the effects of

methane-an extremely potent greenhouse

gas produced by microbes in saturated,

oxygen-free soils-oxygen-rich soils still

released comparatively more carbon.

Thus, the crucial and observing point here

is when that soil becomes exposed to

oxygen. ORNL coauthor David Graham

stated that "If the soils were to drain and

dry, it would be a significant change that

dramatically alters the carbon flux coming

out of the soil".

This finding has helped the scientists to

develop refined models for predicting and

controlling future climatic changes.

"Models help us scale from the present to

the future". Such refined models can

further help to improve estimates of

methane and carbon dioxide release under

rising temperatures and changing soil

moisture conditions.

ORNL's Colleen Iversen has mentioned

that "It's one thing to say, 'What does the

Arctic look like now and what are the

implications for carbon feedbacks?'

But we really want to know what it will

look like at the end of the century. The

only way we can get there is to have

accurate processes in models that are

predicting the future."

Recognizing the importance of soil

moisture and hydrology in the Arctic will

also guide future experimental research in

future projects. This study can thus, help

improve the way the scientists predict the

future climate forecasts and that too in a

more accurate way.
