実験手順: The catalysts used in the present invention include inorganic acids, such as sulfuric acid, hydrochloric acid and phosphoric acid, and organic acids, such as acetic acid, oxalic acid, citric acid, p-toluene sulfonic acid and methane sulfonic acid, among which the strong acids including sulfuric acid, p-toluene, sulfonic acid or methane sulfonic acid are preferred. Propylene glycol monomethyl ether propionate obtained according to the present application has a boiling point of 160.5° C., while other reactants and products having respective boiling point of 120° C. for PGM, 140.8° C. for propionic acid and 100° C. for water. It is apparently easier to rectify this solution comparing the respective boiling point of 146° C. for propylene glycol monomethyl ether acetate, 118° C. for acetic acid and 120° C. for PGM as in the conventional case. This is one of the effects achieved by the process according to the present invention.
