Abstract:The diamyl glutarate was synthesized by esterification of n- amyl alcohol and glutaric anhydride separated from dicarboxylic acid by catalysis of silicotungstic acid. The effects of molar ratio of alcohol/anhydride, the reaction temperature, the reaction time and the amount of the catalyst used were investigated. The conditions of synthesis were determined as follows; molar ratio of alcohol/anhydride 2. 5:1, reaction temperature 140 C, reaction time 90 min, catalyst amount 0. 22% (based on the total mass of reaction system), toluene 10 mL. The esterification rate of the above reaction was up to 96%.
Keywords:diamyl glutarate  synthesis  esterification  silicotungstic acid  catalyst
