1.The diisoamyl glutarate in catalysis of silicotungsticacid was preparated by esterification of isoamyl alcohol and glutaric anhydride seperated from dicarboxylic acid.
用硅钨杂多酸为催化剂,以从二酸中分离出戊二酸酐和异戊醇为原了戊二酸二异戊酯。
2.The synthesis of tridecane dicarboxylic acid diethyl ester with ethyl alcohol and tridecane dicarboxylic acid as reactants and cation exchange resin as catalyst had been studied.
