    Abstract: PURPOSE:To obtain spherical fine particle of silicone having specific constitution unit and particle diameter and effective in imparting water-repellency and slipperiness, etc., to cosmetics, paints, etc., by condensing a silane or a polysiloxane in a solvent such as amine, amide, etc. CONSTITUTION:The objective spherical fine particle of silicone having an average particle diameter of 0.2-20mum and containing >=80% of a polysiloxane composed of (i) 0-20mol.% of a unit of formula I (R is 1-4C alkyl, 2-4C alkenyl or phenyl), (ii) 20-95mol.% of the unit of formula II and (iii) 3-70mol.% of the unit of formula III can be produced by condensing (A) a silane compound and/or polysiloxane in (B) a solvent composed mainly of an amine, amide and/or nitrile excluding nitrogen-containing aromatic heterocyclic compound in the presence of (C) a condensation catalyst.

    Abstract: PURPOSE:To obtain a cycloolefin in high yield, by partially hydrogenating an aromatic hydrocarbon in the presence of water, a hydrogenating catalyst, and an additive consisting of a phosphate compound of Cu, Co and Ni and cobalt sulfate and a compound of GroupIa or ammonium compound. CONSTITUTION:An aromatic hydrocarbon is partially hydrogenated with H2 gas in the presence of water, a hydrogenating catalyst consisting essentially of Ru and one or more selected from a phosphate compound of Cu, Co and Ni and cobalt sulfate and one or more selected from a compound of GroupIa and an ammonium compound as an additive at 50-200 deg.C and 1-200kg/cm to give a cycloolefin. The catalyst may contain a co-catalyst in an amount of 0.01- 0.5 of that of Ru in addition to Ru, and the amount of the additive to be used is 0.1-50 times of that of the catalyst. USE:A raw material for polyamide and lysine.

    Abstract: PURPOSE:To improve the selectivity of a cycloolefin useful as a raw material for polyamides, etc. in partially hydrogenating an aromatic hydrocarbon with hydrogen in the presence of water, a ruthenium hydrogenating catalyst and an additive, by using cobalt sulfate as the additive. CONSTITUTION:An aromatic hydrocarbon, e.g. benzene, toluene, xylene or a lower alkylbenzene, is partially hydrogenated with hydrogen in the presence of water, a ruthenium hydrogenating catalyst containing ruthenium essentially and cobalt sulfate, preferably at 50-200 deg.C 1-200kg/cm to give a cycloolefin by a simple operation in high yilled. The amounts of the water, hydrogenating catalyst and cobalt sulfate are preferably as follows: water in an amount of 0.1-5 times that of the hydrocarbon, 0.1-10wt% hydrogenating catalyst, and 0.001-30 times cobalt sulfate basing on the amount of the hydrogenating catalyst. The hydrogenating catalyst is preferably supported on a carrier, and a co- catalyst, e.g. copper or silver, may be contained therein.
