AN IMPROVED PROCESS FOR PRODUCING HEXABROMOCYCLODODECANE |
摘要 |
This invention relates to the production of an hexabromocyclododecane product, which process comprises brominating cyclododecatriene in the presence of a 1,4-dioxane and water based solvent and from 0.5 to 30 wt% bromide ion in the liquid phase of the reaction mass. Optional post-reaction heat treatment in a finishing step increases process yields if needed. The hexabromocyclododecane product is unrecrystallized and contains no more than about 1.5 wt% tetrabromocyclododecene impurities.
