我们用Fe_2(SO_4)_3·xH_2O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。
We used Fe 2 (SO 4) 3 · xH 2 O as a catalyst to study the solvating ability and kinetics of the dehydration of 2-methyl-2-hexanol to olefins. The reaction rate constants of 20 different solvents and The linear relationship between the solvating ability and the dielectric constant of solvents was determined by the rate constants of the reaction of six kinds of linear alcohols with different contents of propylene and octane. Work in this area has not been reported yet.
