Abstract:
A process for the production of an epoxide, comprisingreacting at least one olefin and hydrogen peroxide,in the presence of a catalyst consisting of titanium silicalite subjected to treatment with an organic molecule comprising an amide group substituted on the nitrogen atom having the general formula: ##STR3## wherein: R.sup.1 is a hydrogen atom or an alkyl radical with from 1 to 20 carbon atoms, an aryl or alkylaryl radical, with from 6 to 20 carbon atoms, a cycloalkyl radical with from 7 to 20 carbon atoms, a heterocyclic radical with one or more heteroatoms, the same or different, selected from the group consisting of N, O and S;R.sub.2 and R.sub.3, the same or different, are alkyl radicals with from 1 to 20 carbon atoms, aryl or alkylaryl radicals, with from 6 to 20 carbon atoms, cycloalkyl radicals with from 7 to 20 carbon atoms, heterocyclic radicals with one or more heteroatoms, the same or different, selected from the group consisting of N, O and S;or the radicals R.sup.1, R.sub.2 and R.sub.3, may form saturated or unsaturated rings in couples, and contain halogen atoms, nitro, nitrite, sulfuric groups, and relative esters, phosphoric groups, and relative esters, carbonyl, hydroxyl, carboxyl, thiol, amine and ether groups.
