摘要:
The present invention relates to the use of low triphenyl phosphate, high phosphorous content aryl phosphates with high ortho alkylation as flame retardants in polyurethane or polyisocyanurate foams or polyurethane or polyisocyanurate foam formulations.
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.
