Abstract
The kinetics of etherification of tert-butanol with aliphatic alcohols on gel KU-2×8 and macroporous KU-23 sulfo cation exchangers was studied. The first order of reaction with respect to tert-butanol and the -CSO3H groups of a catalyst was established. The activation energy of the process observed on KU-2×8 was 60–95 kJ/mol. It was shown that the etherification of tert-butanol on KU-2×8 occurred in a surface layer. The reactivity of primary alcohols introduced into the reaction with tert-butanol increased with their molecular weights (C2–C5). The rate of reaction with secondary alcohols was lower than that with primary alcohols.
