摘要 没食子酸甲酯用对甲苯磺酸代替浓硫酸作催化剂,以庚烷作带水剂进行合成。最佳合成条件为:n(没食子酸):n(甲醇):n(庚烷):n(对甲苯磺酸)=0.055:1.49:0.21:0.0023,在回流温度下反应5h,收率90.4%。 Using toluene sulfonic acid substituted for concentrated sulfuric acid as catalyst, and heptane as water-carrier, methyl gallate was synthesized as follows optimum conditions in a molar ration of gallic acid: methanol: heptane: toluene sulfomic acid=0.055:1.49:0.21:0.0023, reaction time 5h under refluence temperature and 90.4% yield.
