Process for the preparation of glycerol carbonat from glycerol and a cyclic organic carbonat, especially ethylene or propylene carbonate

摘要

A process for the manufacture of glycerol carbonate from glycerol and a cyclic organic carbonate is claimed. The glycerol and cyclic carbonate are reacted in a solvent comprising an organic carbonate or mixt. of carbonates, in the presence of a solid catalyst consisting of an anionic, bi-carbonated or hydroxylated, macroporous resin, or a three dimensional X- or Y-type zeolite having basic sites the diol formed in the reaction is withdrawn.
