A process for preparing 2,2-dimethoxypropane

Abstract

A process for preparing 2,2-dimethoxypropane includes the steps of reacting acetone with methanol in a molar ratio ranging between 1:2 to 1:6 in the presence of a catalyst at a reaction temperature in the range of −50° C. to −80° C., followed by allowing acetone and methanol to react at the reaction temperature in the range of −50° C. to −80° C. for a time period in the range of about 12 hours to 7 days to obtain a reaction mixture including crystals of 2,2-dimethoxypropane; quenching the reaction mixture including crystals of 2,2-dimethoxypropane with a base to obtain a slurry including crystals of 2,2-dimethoxypropane. The slurry including crystals of 2,2-dimethoxypropane is treated to obtain 2,2-dimethoxypropane in a liquid form.
