标题:Continuous synthesis of mercaptocarboxylic acid esters
发明人:LABAT YVES; MULLER JEAN-PIERRE; LITVINE DANIEL
权利人:ELF AQUITAINE
摘要:The invention relates to production of esters of mercaptocarboxylic acids and alcohols forming an azeotrope with water. The esterification is carried out continuously in the presence of an excess of alcohol and the water formed is removed by entraining azeotropically under vacuum at a temperature such that the residual water concentration in the reaction mixture remains constantly below 0.5% by weight. The process according to the invention applies more particularly to the synthesis of octyl esters of thioglycolic acid.

权利人:ATOCHEM ELF SA
摘要:Esters of formula:in which X denotes a C1-C4 alkylene radical and R a C1-C18 alkyl radical, are prepared by reaction of a hydrosulphide with the corresponding halocarboxylic ester:where Y denotes a chlorine or bromine atom. The reaction is performed under a hydrogen sulphide pressure of at least 10 bars absolute, and preferably in an anhydrous or substantially anhydrous alcoholic medium.

标题 :Carbon nanotubes reinforced thermoplastic molding compositions and production process therefor

权利人:BASF AG
摘要:The invention relates to a carbon nanotube reinforced thermoplastic molding composition. This thermoplastic molding composition is produced from a graft copolymer containing single wall carbon nanotubes and a thermoplastic polymer. The graft copolymer is produced from a soft elastomeric particulate graft base with a glass transition temperature below 0°C obtained by emulsion polymerization of a conjugated diene alone or with a small amount of a monoethylenically unsaturated monomer or of at least one C1-C18-alkyl acrylate, or of mixtures of these, upon which is grafted a vinyl aromatic monomer and acrylonitrile and optionally another monoethylenically unsaturated monomer.The synthesis of the aqueous latex of the graft copolymer is performed in the presence of a dispersion of carbon nanotubes (CNTs) in an aqueous medium. For the dispersing step of the carbon nanotubes (CNTs) in aqueous solution, a salt of an amphiphilic polymer is used.
