标 题:Method for the synthesis of organopolysiloxanes containing carbonate groups
发明人：LERSCH PETER; WEITEMEYER CHRISTIAN
权利人:GOLDSCHMIDT AG TH
摘要:The invention relates to a method for the synthesis of organopoiysiloxanes of the general formula which contains cyclic carbonate groups. The inventive compounds have a high polarity, can be synthesized easily and, because of their compatibility with polar media, find use as additives for dispersion paints or lacquers and for coating the surfaces of pigments and fillers.

标 题:Synthesis of the Grape Mealybug Pheromone trans-alpha-Necrodyl Isobutyrate
发明人：CHEBNY VINCENT JAMES
权利人:TRECE INC
摘要:Methods are provided for synthesizing the grape mealybug pheromone, trans-α-necrodyl isobutyrate, starting with essential plant oils that contain trans-α-necrodyl acetate. The synthesis method, in two steps, converts the trans-α-necrodyl acetate to trans-α-necrodol and then converts the trans-α-necrodol to the desired trans-α-necrodyl isobutyrate. The first step can be achieved by either of a hydrolysis reaction or a reduction reaction. In the hydrolysis reaction, the essential oil is mixed in an alcohol solvent with a hydroxide base, or by mixing the essential oil in an aqueous acid. A reduction reaction can instead by performed in an organic solvent in the presence of a reducing agent. The trans-α-necrodol is converted to the desired trans-α-necrodyl isobutyrate by an esterification reaction with a carboxylic acid, an acyl halide, or an acid anhydride.

摘要:This invention relates to a recombinant microorganism capable of producing isoprene and isoprene production with the use of such recombinant microorganism with good efficiency. In this invention, the acetoacetyl-CoA synthase gene encoding an enzyme capable of synthesizing acetoacetyl-CoA from malonyl-CoA and acetyl-CoA and one or more genes involved in isoprene biosynthesis that enables synthesis of isoprene from acetoacetyl-CoA are introduced into a host microorganism.

发明人：ROITMAN LIPA L
权利人:ROITMAN LIPA L
摘要:A process for the synthesis of novel compounds is described comprising reacting tetrachloroethylene with substances containing active methylene group in the presence of free radical initiators. Also, a process for grafting tetrachloroethylene is described comprising reacting these compounds with polymers containing active methylene group in the presence of free radical initiators. Furthermore, a method of conducting such reactions to high conversion is described, comprising conducting the reactions in the reflux condensate. The present invention provides a novel and high yield route for heretofore unobtainable materials.
