  • Synthesis process of polyol carbonate from polyols, conducted in using a solvent selective for polyols carbonates
    Patent number: 8877948
    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.
