Novel efficient synthesis of glycol monoethers over a niobium-containing MCM-41 mesoporous molecular sieve
Abstract
A niobium-containing MCM-41 mesoporous molecular sieve was synthesized by the hydrolysis of tetraethylorthosilicate and niobium pentachloride, using cetylpyridinium bromide as template in acidic medium, and was found to be highly active in the direct conversion of cyclohexene into trans-2-alkoxycyclohexanol at mild temperature in the presence of H2O2 and alcohol.
