| Abstract: | The diisoamyl glutarate in catalysis of silicotungsticacid was preparated by esterification of isoamyl alcohol and glutaric anhydride seperated from dicarboxylic acid. The effect of alcoholanhydride rtio, reaction temperature, reaction time, and the dosage of catalysts etc. was discussed. The process condition of the preparation was determined. The IR spectrum and some performance indications had also been determined. |
