ABSTRACT:
A method of making 2,2-dimethyl-4-(2',3'-epoxy)propoxymethyl-1,3-dioxolane is disclosed, wherein isopropylidene glycerol and epichlorohydrin are reacted in a molar ratio of 0.7:1.0 to 1.0:0.7, respectively, in the presence of at least one Lewis acid or at least one strong inorganic acid at temperatures 283.degree. K. to 373.degree. K., and the initially formed isopropylidene glycerol chlorohydrin ether is reacted with a strongly alkaline base in a molar ratio of chlorohydrin ether to the alkaline base of 1.0:1.0 to 1.0:1.1, respectively, to givbe the 2,2-dimethyl-4-(2',3'-epoxy)propoxymethyl-1,3-dioxolane. This compound is suitable for use as an intermediate for the production of nonionic and/or ionic surfactants, as a reactive diluent and as an auxiliary solvent and auxiliary stabilizer.
