Abstract
Chlorohydrin reactant mixtures containing epichlorohydrin and mono- and dichlorohydrins are selectively hydrolyzed to glycerine by contact with an alkali metal carbonate catalyst, preferably sodium carbonate, at a temperature of about 50.degree. to 70.degree. C for a period of from about 20 to about 150 hours in a two phase agitated reaction system comprising an aqueous phase containing at least about 0.5% by weight alkali metal carbonate and an organic solvent phase having less than about 0.5% weight solubility in water and a dielectric constant of less than about 10, said aqueous phase being about 0.5 to about 10 times the volume of the organic solvent phase.

A process for the production of glycerine from a chlorohydrin reactant mixture containing epichlorohydrin and glycerol mono- and dichlorohydrins which comprises hydrolyzing the chlorohydrin reactant mixture at a temperature of about 50.degree. to about 70.degree. C. by contact with an aqueous phase containing at least 0.5% by weight alkali metal carbonate catalyst in the presence of an organic solvent phase having less than about 0.5% weight solubility in water and a dielectric constant of less than about 10, said aqueous phase being about 0.5 to about 10 times the volume of the organic solvent phase, for a period of from about 20 to about 150 hours.
