Process for the monoepoxidation of compounds containing two double bonds.
@ The invention relates to a process for the monoepoxidation of compounds containing two olephinic double bonds by
means of hydrogen peroxide in the presence of a catalyst
constituted by a Si-Ti synthetic zeolite (titanium-silicalite),
wherein Ti and Si in the form of their oxides TiO2 and SiO2
have a molar ratio in the zeolite corresponding to the formula
x TiO2 @
(1-x)SiO2
CO
with
within the range of from 0.0001 to
< 0.04, x being comprised
preferably of from 0.0055 to 0.036, possibly in the
presence of at least one solvent of polar nature, by operat0 ) ing with the heterogeneous catalyst being dispersed in the
o liquid phase at a temperature of from 0°C to 150 °C, and
under a pressure comprised within the range of from 0.1
abs.atm to 20 abs.atm.
