合成草酸二异戊酯的催化剂选择

Selection of Catalystins in the Synthesis of Oxalic Acid Diisopentyl Ester

分别以浓硫酸、磷钨酸、７３２型阳离子交换树脂为催化剂合成草酸二异戊酯。实验表明，７３２型阳离子交换树脂具有催化性能良好、成本较低、反应工艺简便、设备无腐蚀、无污染、产品收率高、质量稳定等优点．

A synthetic technique of Oxalic acid diisopentyl ester with different kinds of catalystins isintroduced.Compared with Sulphuric acid and Phosphato-tungstic acid,Cation exchange resin 732has more advantages in catalytic esterification。
