The results of 1-buten-3-ol (1B3O) epoxidation with 30% hydrogen peroxide over the Ti-Beta catalyst were presented. The studies were performed under the atmospheric pressure and at the presence of methanol as a solvent. There was examined the influence of the following parameters: the temperature (0 - 60°C), the molar ratio of 1B3O/H2O2 (1:1 - 5:1), methanol concentration (5 - 90 wt%), the Ti-Beta catalyst concentration (0.1 - 5.0 wt%) and the reaction time (0.5 - 5.0 h). The optimal parameters were determined by using the following functions: the selectivity of the transformation to 1,2-epoxy-3-butanol (1,2E3B) in relation to 1B3O consumed, the selectivity of the transformation to organic compounds in relation to hydrogen peroxide consumed, the conversions of 1B3O and hydrogen peroxide. The main product of epoxidation was 1,2-epoxy-3-butanol, epoxide having several applications.
