Abstract
A process for the epoxidation of olefinic compounds, consisting of reacting said compounds with hydrogen peroxide either introduced as such or produced by substances capable of generating it under the reaction conditions, in the presence of synthetic zeolites containing titanium atoms, of general formula: xTiO.sub.2.(1-x)SiO.sub.2, where x lies between 0.0001 and 0.04, and possibly in the presence of one or more solvents, operating at a temperature of between 0.degree. and 150.degree. C., and at a pressure of between 1 and 100 ata.

A process for the expoxidation of olefinic compounds, characterised by reacting said compounds with hydrogen peroxide either introduced as such or produced by substances capable of generating it under the reaction conditions, in the presence of synthetic zeolites containing titanium atoms, of the following general formula:
- xTiO.sub.2.(1-x)SiO.sub.2
- where x lies between 0.0001 and 0.04, and possibly in the presence of one or more solvents.
A process for the epoxidation of olefinic compounds said process consisting essentially of the reaction of an olefin with 10-70% w/v aqueous hydrogen peroxide at a molar ratio of hydrogen peroxide to olefin of between 10 and 90% at a temperature of 0.degree.-150.degree. C. and a pressure of 1-100 atmosphere in the presence of a polar solvent and synthetic zeolites containing titanium atoms, of the general formula:
- x TiO.sub.2 .sub.( 1-x) SiO.sub.2
- wherein x lies between 0.0001 and 0.04.
