METHOD OF PRODUCING GLYCEROL DICHLOROHYDRINS Russian patent published in 2013 - IPC C07C29/62 C07C31/36

Abstract RU 2499788 C1

FIELD: chemistry.

SUBSTANCE: method involves dichlorinating glycerol with gaseous hydrogen chloride at temperature of 70-140°C in the presence of a carboxylic acid and a water-insoluble organic solvent, wherein the process is carried out in a combined reaction/rectification reactor, and the organic solvent is selected such that it forms an azeotrope with water but not with glycerol dichlorohydrins.

EFFECT: method reduces contact time and increases output of glycerol dichlorohydrins.
