发明名称 PREPARATION OF HIGH ASSAY DECABROMODIPHENYL OXIDE
摘要 Process technology for producing very pure reaction-derived decabromodiphenyl oxide is described. Diphenyl oxide or partially brominated diphenyl oxide or a mixture of either or both of these is fed substantially continuously over a period of about 2 to about 12 hours into a reactor containing an excess of refluxing bromine containing Lewis acid bromination catalyst, and substantially concurrently reducing the content of hydrogen bromide present in the reactor whereby a decabromodiphenyl oxide product having a purity of over 99%, preferably 99.5% or more, is formed in the reactor.
