SYNTHESIS PROCESS OF POLYOL CARBONATE FROM POLYOLS, CONDUCTED IN USING A SOLVENT SELECTIVE FOR POLYOLS CARBONATES

Torna indietro

Abstract

The present invention relates to a synthesis process of polyol carbonate, such as glycerol carbonate, from polyols such as glycerol, propylene glycol or ethylene glycol and urea conducted in using a solvent selective for polyols (glycerol) carbonates. Said process comprises reacting polyol with urea in the presence of a catalyst, extracting produced NH3 and in addition in the presence in the course of at least one step of the process of a selective solvent for polyol carbonate allowing to extract it from the reaction medium.
