CHAPT".tiR 7 • :BORON (:810)

a. marly in 1943, the Loa Alanoe Laboratory indicated a need !o~

qwuiti ties ot cryatalline boron ot normal 1aotop1o content and c17•tal-

line boron enriched in Bi.O (see Book VIII, Vol. 2). Production of the

material• waa initially reg~rded as extremely important and ver, essential

to the overall Manhattan District 9.0tivi ty. While neoeesi ty for the

materials was somewhat modified. a. t a l a ter de.te 1 nevertheless. from the

be«inn1ng the. boron project was given the highest priorit7 and every

e:tf ort was made to assure t hat production vould be as prompt and a.a

effici~nt as possible. The original requirem&nts included the utmos'

secrec7 and minimum public1t7 in all phaees ot the material production.

O<>mpliance w1 th the aecuri t,. restriction.• ca.used many of the nego\1a.tion1

to be conducted through oral discussion and thua limited correapondence

and records to bare essentials.

b. The desired materiale were obtained through1 reaearoh and

developmellt by Columbia Un1vers1t7 {SAM taboratoriet) ; developmen\ and

and its respective performance vtlt be referred to herein under a

separate heading.

r c. Namee of personnel involved 1n the boron procurement act1v1tie&

m8¥ be found in the appendices to th1e chapter , and in other vol'Wllet ot

the .Hh tory, to which ref'erenoes '11111 be made hereinafter. Those who

were oost concerned included the following:

Dr. J . R. Oppenheimer, of Loa Alamos taborato1y;

Dr. K. c. Urey and Dr . Martin Xilpatrlck, ot Columbia

Univera1t1 (SAM Laborator1e•):

Dr. Oyr11 s. Smith, ot the Horton Co11pan7;

Mr. E. G. Seubert and Dr. E. W. Thiele , of Standard 011

Comp&nT ot Indlaiia;

M&J. Gen. L. R. Groves and Lt. Col . J . R. Ruhoff , ot the

Manhattan Dis~riot.

2. Columbia Un1Yere1tr. (Refer t o App. A-1 . )

a.. In Mal-7 1943, the request of the Loa Alamo• Laboratory, described

above, waa diaouseed between repre1entative1 of Columbi a UniTersit7 and

the Madison Square Ar ea. That disouaaion resulted in arrangementa where­

by, under Contract W- 74<>5- en&-50, Columbia 'On1Terait7 was to proceed with

the necesaar1feesearch and development for the pr oduction of 500 to 1000

powids of cryatalline boron of normal iaotopic conten' and 50 kilogr&lla

o! cryatalline boron containing no' lee• than 90~ ~o.

b. The need for thia work had been anticipated by personnel at

Columbia a.nd four months earlier (in Janua.r7 1943) , under OSRD Contrac~

O";]Msr 412, r e earch on the separation ot boron isotope• had been started.

That researoh had resulted, in April 1943, in the discovery of a promis i ng

method ot operation. Such a method ot operation waa still being investi-

gated when the Had.ison Squs..re Area arro.ngementa became effective, but

the tnformation ~hieh had already been obtained was GUCh that develop.

men1i could• d dtd, proceed "71 th a minimum ot dela.y. The separ a ttoa

procedure , which w9a proven to be suocessf'u.l by continued inveettgat1on

and. plant operaiion, was based o~ $ counter-cttrrent dlstlllatloa ot a ·

dissociable complex or pol71Der.

e. Ia add1 tion to the atud7 for separation of boron iae>topes ,

Columbia 1~1thted a research program concerned '11th trut reduction ot

, production applied to materia.l of normal isotopic content and was

!3.CCompl1shed under Contract \f- 74o5-eng•292, effective 15 Januacy- 1944.

at a cost of $53.000 (See Book VII , Vol. 1) . Government- owned rav

material , which had been obtained from the Nia&ara Smelting Company, was

supplied to tho Norton Comp8.ll¥ for their process.

Con:f'1rmill4J records and supporting data for the Norton Compan.7 parti-

oipat1on in the boron proJect are, of necessity, extr emely eketchT. ae

particular care waa exercised t o prevent general knowledge ot their

s~tivity being divulged.

4. The H&rahaw Chemical Compg.

The Rarshaw Chemical Compallf vas selected t o supply raw material

for the Standard Oil procee1 of the boron proJec t . Contract W-7~5-eng-

289, effective 15 March 19411.. called tor a suppl7 of 650 pounds of

"synthanelt per \lteek for aix montha , starting l Ma7 1944. 11 S7Jithane 11 was

the code s1Jllbol for boron trifluoride containing not leaa than 97% ot

Bl3 of a s oonetan\ pur1t7 ae possible. SUbaequ.ent supplements to the

contract increased the quantity of raw material to a total of 92, 450

pounds , a t a total contract price ot $72, 770 (see .Book VII , Vol . l) .

Rav material delivecy- wae completed l March 1946.

5. Stand.a.rd 011 Company of Indiana.

~lhen research and development a t Columbia University had progressed

to a stage which permitted design and construction ot a production plant

for the separ a tion ot boron isotopes , contact was made with the Standard

011 Company of India.na (App. A-2, 3 & 4) . That company indica t ed its

3groement to partic ip~te in the pr ojec t ~nd on 5 J anuary 1944 antered

in t o Contract .v- 7418- eng-41 . The contr ac t ·~as effective as of 2 December

1943, the con t empla ted work cons isting of the design, erec t i on a.nd

operation of a aui table pr oduction plant for the s eparation of boron

i sotopes. In addition to the above work it was understood that the

St andard Oil CompBn¥ ~ould undertake work directed tovard~ increasing

t he oer ta.inty of the aarl1 success ot t he propoaed proj ect; training

of t echnical a~d non- toohnical personnel; and1 establishin« an &.dequate

securi t y sy~tem.

A g~nera.l history ot the contractor's activity in meeting contra.ctu.al

requirements is provided in Appendix 5. That history of t he separa­

tion project describes: the work objective& selection of the production

contrnctora plant des ign fea tures; initial opera tions supple~entar;y

plant conaiderat1ona1 and the then tutu.re possibilities of t he process.

difficulti es in obtaining desired conatruction material (App. A-6) , a.rid

the i nadvertent 1ntrodua\1on ot mercury into the plant sy$tem during

the leak tes t procedure (App. A-5) . 'l'he latter d1fficult7 waa considered

to be quite aerioue in 1ta nature and lad to the erroneous conclusion

that the initial plant would be unsuitable for production and tha• re-

pla c ement would be re quired. r.a ter on during the contrac~ a corrective

measure was d i scovered and the origin.s.l plant proTed to be operable for

pr oducti on purpos a .

the production of separated complex froo the Stand'3rd Oil Company of

Indiana. The rate of production of the sep~rated complex had been estnb-

lished, by the Chicego Area sud the Stcndard 011 Company , to be 5 gallons

every three da¥B• The plant of the American Cyanamid Company was designed

to run at twice this rate if necessary, since the Chicago Area had. int!-

nl!l. ted that the¥ might be able to rrange for an i ncrease in the r a te of

separation. The American Cyanamid Comp~•ny plant had undergone test rune

and was ready to ope re te by 7 July 1941.,.. Unforturu tely, material we.a not

available at that time from the S\e.ndard 011 Compan~-. '"'bile nw111 ting

material from the Standard Oil Company, work continued at the American

Cyanamid Company. to improve their process and to prevent possible loasea

of material . Upon the start o! delivery- of the 890 A complex from the

Standard 011 Company , the American C1anamid facilities were in re~dinesa

and proceon!ng to the final product began.

In accordanoe with su:p.;?lementa.17 requirements !or contract w-74o1-

eng-91 , production a t the American Cyanamid Comp~ continued well into

1946, and 504 pounds of crystalline boron 10, 850 pounds of calcium

fluoride- boron trifluoride complex, containing a greater than normal r a tio

of the BlO isotope , and 242 pounds of calcium fluoride- boron trifluoride

complex, containing a greater t han norr.:ial ra tio of B11 , ~as obtained

(see 3ook VII , Vol . l) .

1 . The work being undertaken is the separation c)f isotope Boron 10 from Doron J.l . The light component is desired at 95% purity. Boron tri-fluorid will be the basic material . Thie ce.n be procured as a com-ponent . Doron tri-fluori e and nethyl other 1'1ill i'orn.1 a complex 1 hioh boils at ahout 200oC . It bas been determined thut the lleht complex haa a dif.f erAnt vapor pressure than the heavy complex and will boi l off at a sliehtly lower temperature . It is believed that the sepa:itatlon can be obtained by distillation. The Job is var; difficult , howevor; ecause

the difference of volatility is hout one pa r t i L a thousand. It is con­tar:1plated that fractionating quipment consisting of al.~out a thousand theoretical plates l'7ill e used and that the equipment \70Uld oporate at about a thou­sand to one reflux ratio,,-. Boron tri• fluoride and , t.hyl othor a:re both !~ases but the complex is liquid . 'l'he .uipmAnt. as contemplated will con­sist of nine columns 35 feet high . The first three will cons~ of thi rteen (}• triangles, the second three of five 6" triangles , and third' three of 6n dirunetGr tubes . The chemical engineering job concerned is to get the holtlup aa low as possible and slso prevent c.ecomposi t.ion of the com-plex . This latter will not only ruin production but also oause corrotiion of the diatillating columns . To decrease corrosion, monel packing will be used . The components uill be deL~v red as eases and it is e..xpccted that these will be formed in the complex at the oita . This acheme has been t1orkod out at Columbia and no difficulty is xpeoted in effecting the for-mation ofthe complex •

'i'hen it was received, it was f owid t o be in an un­suitable form due t o oale and irregular surf oes s nd !urthar delay waa incurred in prepar ing the plate for fabrication . As a resul t of t hese de­lays , the completion dates of t he f abricated sections or the hexagonal tol1ers have been placed t around 60 days :Crom 8 ?.!ay 1944. There ar e tT10 authentic but conflicting otat ern nts with r egard t o the dat e on which the sections can be completed. 'l'!le exact delay cnn not be determined at this t ime .
