PROCEDIMENTO PER PREPARARE PENTAE RITRITI BROMURATE E LORO ESTERI E PRODOTTI COSI OTTENUTI

摘要

Brominated pentaerythritols and esters, and useful mixtures of same, are prepared utilizing certain aliphatic saturated dicarboxylic acids or their anhydrides having from 3 to 10 carbon atoms in the molecule or certain aliphatic monoethylenically unsaturated dicarboxylic acids or their anhydrides having from 4 to 5 carbon atoms in the molecule where pentaerythritol is contacted with HBr and the dicarboxylic acids in the liquid phase under conditions where bromine and the carboxyls of the acids replace the hydroxyls of the pentaerythritol.
