Abstract

Epoxidation of 1-butene-3-ol (1B3O) with 30 wt% hydrogen peroxide over TS-2 catalyst has been studied with methanol as a solvent and at elevated pressure (autogenic). The influence of temperature in the range of 20-120 degrees C, the molar ratio of 1B3O/H(2)O(2) 1:1-5:1, methanol concentration 5-90 wt%, TS-2 catalyst concentration 0.1-5.0 wt% and the reaction time 0.5-5.0 h have been investigated. The process was described by the following functions: the selectivity of transformation to 1,2-epoxybutane-3-ol (1,2EB3) in relation to 1B3O consumed, the selectivity of transformation to organic compounds in relation to H(2)O(2) consumed and the conversions of 1B3O and hydrogen peroxide. The major product of epoxidation is 1,2EB3, a compound with many applications.
