硫酸氢钾催化合成没食子酸辛酯

Synthesis of Octyl Gallate Catalyzed by Potassium Bisulfate

采用硫酸氢钾为催化剂合成了没食子酸辛酯,考察了催化剂用量、醇酸物质的量比、反应时间及带水剂用量等因素对收率的影响。结果表明该催化剂具有催化活性高,价廉易得,易于保存,使用方便,产品收率高等优点。适宜条件下收率为99.2%。

By using potassium bisulfate as the catalyst, octyl gallate was synthesized. The effects including the amount of the catalyst, the reaction time, the molar ratio of alcohol to acid, the amount of carrying water agent on the yield of the production are investigated. It showed that the catalyst was efficient, economic and convenient to use. the yield could reach to 99.2% with the appropriate conditions.
