  • Process for the manufacture of epoxides
    Patent number: 5086189
    Abstract: 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.
    Type: Grant
    Filed: February 2, 1990
    Date of Patent: February 4, 1992

  • Process for the preparation of carboxyl compounds
    Patent number: 4353832
    Abstract: 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.
