叔醇脱水成烯反应的溶剂化能力与介电常数的关系

Relationship Between Solvating Power and Dielectric Constants for the Dehydration of Tertiary Alcohol to Alkenes

我们用Fe2（SO4）3·xH2O为催化剂,对2-甲基-2-已醇脱水生成烯烃反应的溶剂化能力及其动力学做了研究,测定了20种不同溶剂中的反应速率常数和以丙至辛6种直链醇为溶剂于不同温度下反应的速率常数,确定了溶剂化能力与溶剂介电常数之间的线性关系。这方面工作尚未见报道。

Solvent effects on the dehydration of 2-methyl-2-hexanol to corresponding alkenes, catal-lyzed by Fe2(SO4)3 . xH2O, were determined in different solvents. The relationship between solvating power and dielectric constants was derived from these experimental data.
