57-61

Epoxidation of crotyl alcohol (CA) with 30 wt% hydrogen peroxide over Ti-MWW catalyst has been studied with methanol as a solvent and at autogenic pressure. The influence of temperature in the range of 20 – 120oC, the molar ratio of CA/H2O21:1-5:1, methanol concentration 5 – 90 wt%, Ti-MWW catalyst concentration 0.0 – 5.0 wt% and the reaction time 5 – 300 min have been studied. The main product of CA epoxidation is 2,3-epoxybutane-1-ol (2,3EB1O), a compound with many applications.

The results of the epoxidation of 2-buten-1-ol with 30 wt% hydrogen peroxide have been presented. As a solvent methanol was used. The process was carried out over the titanium silicalite catalysts: Ti-MCM-41 and Ti-MCM-48. The influence of temperature (20 - 120°C). the molar ratio of CRA/H2O2 (5:1 - 5:1), methanol concentration (5 - 90 wt%), catalyst concentration (0.1 - 5.0 wt%) and the reaction time (30 -300 min) was investigated. The obtained results were used for the determination of optimum conditions of running the epoxidation process of 2-buten-1-ol.
