Abstract: The invention aims at providing an oxidizing agent composition capable of producing halogen-free epoxy compounds in high yield; and a process for the epoxidation of olefins with the composition. In order to attain the aim, the invention provides an oxidizing agent composition for the epoxidation of olefins which is characterized by containing an acid anhydride and a solid hydrogen peroxide adduct; and a process for the epoxidation of olefins which is characterized by reacting an olefin with a mixture obtained by mixing an acid anhydride with a solid hydrogen peroxide adduct.

Abstract: This invention relates to a process for the production of an alkanesulfionic acid such as isethionic acid with a high purity in a high yield and at a low cost by oxidation of a (hydroxy)alkylmercaptan with hydrogen peroxide characterized in that a whole amount beyond a stoichiometric amount of a solution of hydrogen peroxide having a H.sub.2 O.sub.2 concentration of not less than 50% by weight is charged into a reaction vessel, said mercaptan is continuously fed at a temperature of 50.degree. C. or lower, aging is carried out, distillation with boiling is carried out and then the reaction mixture is contacted with an anion exchanger.

Abstract: Styrene oxide is prepared by reacting styrene and hydrogen peroxide in a heterogenous system in the presence of a bis(tri-n-alkyltinoxy) molybdic acid and an inorganic anion.

Abstract: A novel water-soluble produced by contacting thiourea dioxide with an aqueous solution comprising an amino acid having the general formula NH.sub.2 (CH.sub.2).sub.n COOH wherein n is an integer of 1 to 7 and a sodium, potassium or calcium salt of acetic acid.

Abstract: Styrene oxide is prepared by reacting styrene and hydrogen peroxide in a heterogeneous system in the presence of a bis(tri-n-alkyltinoxy)molybdic acid and an amine represented by the following general formula: ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 each independently represent H, CH.sub.3, C.sub.2 H.sub.5, C.sub.3 H.sub.7, C.sub.4 H.sub.9, or HOCH.sub.2 CH.sub.2.

Abstract: An amine-substituted thiourea dioxide is obtained by reacting thiourea dioxide and an aliphatic or aromatic primary amine in a neutral or acidic pH range.
