标 题:Reagent and process for the synthesis of oxysulphide-containing fluorine-containing organic derivatives
发明人：FORAT GERARD; MAS JEAN-MANUEL; SAINT-JALMES LAURENT
权利人:RHONE POULENC CHIMIE
摘要:The invention relates to a reagent which is useful for the synthesis of oxysulphide-containing fluorine-containing organic derivatives by reacting with an oxide of sulphur, especially sulphur dioxide, characterized in that it comprises: a) a fluorocarboxylic acid of formula Ew-CF2-COOH where Ew is an electron-withdrawing group or atom which is at least partially salified by an organic or inorganic cation, and b) an aprotic polar solvent; and in that the content of releasable protons carried by its various components, including their impurities, is at most equal to half the initial molar concentration of the said fluorocarboxylic acid. This reagent can be used by heating in order to form fluorine-containing sulphinic or sulphonic acids.

标题 :Synthesis of polyalkylenepolyamines having a low color index by homogeneously catalyzed alcohol amination in the presence of hydrogen
发明人：STRAUTMANN JULIA; SCHAUB THOMAS; HUEFFER STEPHAN; MAAS STEFFEN; PACIELLO ROCCO
权利人:STRAUTMANN JULIA; SCHAUB THOMAS; HUEFFER STEPHAN; MAAS STEFFEN; PACIELLO ROCCO; BASF SE
摘要:Process for the preparation of polyalkylenepolyamines by homogeneously catalyzed alcohol amination, in which aliphatic amino alcohols are reacted with one another or aliphatic diamines or polyamines are reacted with aliphatic diols or polyols with the elimination of water in the presence of a homogeneous catalyst and in the presence of hydrogen gas. Polyalkylenepolyamines obtainable by such processes and polyalkylenepolyamines comprising hydroxy groups, secondary amines or tertiary amines. Uses of such polyalkylenepolyamines as adhesion promoters for printing inks, adhesion promoters in composite films, cohesion promoters for adhesives, crosslinkers/curing agents for resins, primers for paints, wet-adhesion promoters for emulsion paints, complexing agents and flocculating agents, penetration assistants in wood preservation, corrosion inhibitors, immobilizing agents for proteins and enzymes.
