Epoxides are manufactured by reacting olefines, such as cyclohexene, isoamylene, alpha-pinene, allyl alcohol, 2,5-dihydrofuran and styrene, with hydrogen peroxide, in a homogeneous liquid reaction mixture containing less than 10% by weight of water, in the presence of a compound of a metal of group 6a, such as selenium dioxide or selenous acid, and of an organic nitrogen-containing base having a pKa of not more than 8, such as pyridine, chloropyridine, collidine, quinoline, isoquinoline or a lutidine.

Process for the manufacture of epoxides

Aromatic tertiary amines are oxidized by means of hydrogen peroxide in an inert solvent medium in the presence of a catalyst selected from metal selenium and compounds of selenium. The process is applied to the preparation of oxides of heterocyclic aromatic tertiary amines and oxides of non-heterocyclic tertiary amines, in which the nitrogen atom is substituted by at least 1 aromatic nucleus.

Process for the production of oxides of aromatic tertiary amines

Process for the catalytic synthesis of nitrogen-containing organic compounds, comprising the reaction of carbon monoxide with at least one amino compound in a reaction mixture containing a catalyst based on selenium and a substituted pyridine. The process is particularly suitable for the synthesis of ureas and of their polymers.

Catalytic synthesis of urea from carbon monoxide and amine compound

2,2,2-Trifluoroethanol is obtained by catalytic oxidation of 1,1-difluoroethylene. The 2,2,2-trifluoroethanol thus obtained is used as a solvent or as a synthesis intermediate.

Process for the preparation of 2,2,2-trifluoroethanol

A process for the production of carboxyl compounds such as caprolactones, in which the corresponding carbonyl compounds are oxidized with hydrogen peroxide in the presence of a catalyst in a substantially anhydrous liquid medium. The water formed by the reaction and any water introduced into the reaction mixture are removed from the reaction mixture.
