| Abstract: | In this paper the synthesis of propyl gallate from gallic acid and n-propyl alcohol as reactants and catalyzed by sodium bisulfate was studied; various influencing factors on the reaction were also investigated. The optimal reaction conditions were determined as follows: the molar ratio of gallic acid/n-propyl alcohol/sodium bisulfate was 1/14/0.058, in the reaction of 5 h a propyl gallate yield of about 93.8% could be obtained. |
