    摘要： A crude vinylically unsaturated product formed from a palladium-complex-catalyzed reaction of a reactant halide selected from the group consisting of aryl, allyl, vinyl, and benzyl halides, and a reactant olefin having a vinylic hydrogen, wherein the reaction is carried out in the presence of a hydrogen halide acceptor, is purified by first contacting the crude product with a base that is stronger than the hydrogen halide acceptor, then heating the stronger base-contacted product. The purified product shows a marked reduction in concentration bromine and palladium impurities. The product can then be further purified by such methods as chromatography, crystallization, or distillation to achieve a product that is more suitable for applications where very low levels of inorganic impurities are required.

    摘要： 884,807. Siloxane compositions. FARBENFABRIKEN BAYER A.G. July 17, 1959 [July 26, 1958], No. 24707/59. Class 2(7) A composition comprises a siloxane of the formula wherein R is a hydrocarbon radical of at least 2 C atoms and n is an integer from 1 to 10, and a liquid, pasty or waxy, organic compound, e.g. alcohols with a low water content such as methanol, ethanol, isopropanol, butanol, 2-ethylhexanol and amyl, cetyl, lauryl and stearyl alcohols; benzine, benzene, toluene, beeswax, mineral oil, ceresine, paraffin and petroleum; oleic and stearic acids; butyl-acetate, -oleate and -stearate, glycerol monostearate, isopropyllaurate, -myristate, -palmitate and -stearate, lanoline, methyl phthalate, sesame oil and olive oil; diethyl and diisopropyl ethers; chloroform, carbon tetrachloride and trichloroethylene. The siloxanes are obtained by cohydrolyzing a mixture of more than 1 mol. but not more than 3 mols. of (CH 3 )SiCl and I mol. of RSiCl 3 with half the molar amount of water as there are gram atoms of chlorine in the silane mixture, and subsequently heating the reaction mixture to 100‹ C. until it is free from HC1. If desired the reaction product may be fractionated. Siloxanes in which R is phenyl, n-butyl and ethyl are disclosed and their miscibility with organic compounds is compared with that of other siloxanes. Uses: mould release agents; cosmetic preparations. Specification 848,719 is referred to.
