Abstract

The aminolysis of a novel activated ester resin was utilized for kinetic study via continuous in situ fluorescence measurements. A variety of resin compositions (polystyrene, JandaJel, ArgoPore, TentaGel, NovaGel, and PEGA) and solvents (dimethylformamide, acetonitrile, tetrahydrofuran, 1,2-dichlorethane, and toluene) were tested to compare their effects on the reaction rate. A linear relationship between the reaction rate and (solvent polarity x swelling of resin) was elucidated for the aminolysis reaction.

摘要

通过连续原位荧光测量，利用一种新型活性酯树脂的氨解反应进行动力学研究。测试了多种树脂组成（聚苯乙烯、JandaJel、ArgoPore、TentaGel、NovaGel和PEGA）和溶剂（二甲基甲酰胺、乙腈、四氢呋喃、1,2-二氯乙烷和甲苯），以比较它们对反应速率的影响。阐明了氨解反应中反应速率与（溶剂极性×树脂溶胀）之间的线性关系。
