    摘要: A modified silicone compound having a branch polymer comprising a hydrophilic group, this compound being synthesized by performing an addition reaction between an organohydrogenpolysiloxane, and at least one compound chosen from an alkenylated polyoxyalkenylated compound, an alkenylated glycerine compound and an alkenylated sugar in the presence of a platinum catalyst or rhodium catalyst, and a cosmetic material containing this modified silicone compound. This compound is purified by decomposing aldehyde condensation products remaining in the silicone by alkylating the remaining unsaturated bonds after hydrogenating the reaction liquor after said addition reaction, and treating with an aqueous solution of pH 7 or lower containing an acidic substance, or decomposing the propenyl etherated polyether in the reaction liquor after said addition reaction by treating with an aqueous solution of pH 7 or lower containing an acidic substance, and then alkylating the generated aldehydes and alkenylated ether compounds by hydrogenation. The degree of unsaturation (meq/g) in the modified silicone compound is 0.002 or less. The generation amount of aldehydes when heat ageing is performed in 0.23N hydrochloric acid at 50° C. for 0.5 hours is 70 ppm or less of the modified silicone compound.

    摘要: Alkylhalosilanes are produced by first fluidizing a metallic silicon powder with an inert gas, preheating the silicon powder at a temperature between 200.degree. C. and a steady reaction temperature while keeping the silicon powder fluidized, adding a copper catalyst to the preheated silicon powder to form a contact mass, and feeding an alkyl halide into the contact mass whereby the alkylhalosilanes are formed by direct synthesis. This process prevents the copper catalyst from being sintered by thermal hysteresis and activates a high catalysis on the contact mass at the start of reaction. The desired dialkyldihalosilane can be produced at a high selectivity.

    摘要: An alkylhalosilane is prepared by charging a reactor with a contact mass comprising a metallic silicon powder and a copper catalyst, and feeding an alkyl halide into the reactor whereby the silane is formed by direct synthesis. The contact mass contains 1-10,000 ppm of elemental boron. The addition of boron to the contact mass is effective for increasing the throughput of dialkyldihalosilane at desired STY in an inexpensive manner while suppressing formation of unnecessary hydrosilanes and disilanes.

    摘要: An alkylhalosilane is prepared by charging a reactor with a contact mass comprising metallic silicon powder and a copper catalyst and feeding a reactant gas containing an alkyl halide into the reactor whereby the silane is formed by direct synthesis. A phosphorus compound is added to the contact mass in an amount of 3,000-10,000 ppm calculated as phosphorus. The invention produces a more amount of dialkyldihalosilane in a desirable STY while minimizing the amount of unnecessary disilanes.

    摘要: An improved flame-retardant composition and method for its use are provided. The composition imparts flame retardency to synthetic thermoplastic resins to prevent dripping of the melt of the resin when the resin is burnt. The composition comprises a flame retardant agent such as phosphate ester compound, optionally combined with a metal hydroxide, and an organopoly-siloxane-based graft copolymer of a (meth)acrylic acid ester such as methyl(meth)-acrylate. The flame retardant is used in an amount from 1-50 parts by weight per 100 parts by weight of the synthetic resin, and the graft copolymer provides 0.5 to 20 parts by weight of an organosilicone group per 100 parts by weight of the synthetic resin.
