Beilstein testFlame Test for Mod-Acrylic and Polyvenyle Fiber:
For the Beilstein test, the initial heating of the Copper wire is to promote the reaction: Cu (s) + O2 (g) --> CuO (s) A positive Beilstein test is based upon the reaction of the Organic halide with the Copper oxide: CuO + 2 R-X --> CuX2 + 2 R-O It is the volatile CuX2 compound which gives the flame a blue-green color during the flame test
