Abstract
This invention relates to a novel process which comprises feeding a mixture formed from diphenylethane and bromine to a stirrable reaction mass comprised of bromine and a bromination catalyst to yield a decabromodiphenylethane wet cake which can be most economically treated to provide a high quality decabromodiphenylethane product.
Claims47
A process for the manufacture of a decabromodiphenylethane product, which process comprises:
- a) generating a mixture from at least bromine and molten diphenylethane in a molar ratio of bromine to molten diphenylethane of at least about 5:1;
- and
- b) feeding said mixture into a stirrable reaction mass comprising bromine and a bromination catalyst.
A process for the manufacture of a decabromodiphenylethane product, which process comprises:
- a) feeding bromine and diphenylethane to a mixer in a molar ratio of bromine to molten diphenylethane that is within the range of from about 5:1 to about 30:1 to at least partially form a mix;
- and
- b) feeding the mix into a reaction mass containing bromine and a bromination catalyst.
