Abstract
The invention relates to a process for the preparation of bromine-containing polyols in which a bromine-containing alcohol is caused to react with an alkylene oxide in admixture with other H-functional compounds and the catalyst used is a system comprising alkaline and Lewis-acid catalysts.
Claims19
A process for the preparation of bromine-containing polyols, comprising the steps of reacting a bromine-containing alcohol with an alkylene oxide in admixture with H-functional compounds, introducing a catalyst comprising alkaline and Lewis-acid catalysts into said admixture, and thereafter separating the bromine-containing polyols from the resulting by-products, if any.
A process for the preparation of bromine-containing polyols wherein the occurrence of side reactions and the evolution of bromine are substantially suppressed, comprising the steps of homogeneously mixing and reacting a bromine-containing alcohol, an alkylene oxide, one or more H-functional compounds and a catalyst to form a bromine-containing polyol and separating the resulting bromine containing polyol from the resulting by-products, if any.
