标 题:Method for synthesis of aliphatic isocyanates from aromatic isocyanates
发明人：LETTMANN CHRISTIAN; KOHLSTRUK STEPHAN; STOCHNIOL GUIDO; SPYROU EMMANOUIL
权利人:DEGUSSA
摘要:The invention relates to a method for synthesis of aliphatic isocyanates from aromatic isocyanates in substantially 3 stages. In particular, the invention relates to a method for synthesis of bis{4-isocyanatocyclohexyl}methane (H 12 MDI) from bis{4-isocyanatophenyl}methane (MDI). More especially, the invention relates to a method for synthesis of H 12 MDI with a trans-trans isomer content of <30%, preferably of <20%, particularly preferably of 5 to 15%.

标 题 :Process for the synthesis of α-substituted acroleins
发明人：DESHPANDE RAJ M; DIWAKAR MAKARAND M; CHAUDHARI RAGHUNATH V
权利人:COUNCIL SCIENT IND RES
摘要:The present invention provides an improved process for the synthesis of α-substituted acroleins from olefins by a tandem hydroformylation and Mannich reaction sequence in the presence of syngas and formaldehyde, wherein the two catalysts are segregated into two different phases thereby preventing deactivation of the catalysts by each other, and yielding a highly selective and active catalyst.

标 题 :Stereo-selective synthesis of 2-aryl-propionic acids of high optical purity by using chiral oxazolines
发明人：PARADIES HENRICH H
权利人:PARADIES HENRICH H
摘要:The present invention relates to a stereospecific chemical synthesis of optically pure enantiomers of 2-aryl-alkanoic acids, especially those of the biologically active (S)-aryl-propionic acids, in good chemical yields, useful for preparing large quantities thereof, and having a high optical purity.

标 题 :Synthesis of glycerol from formaldehyde
发明人：GRACEY BENJAMIN P; HUDSON BARRY; WILLIAMS PETER S
权利人:BP CHEM INT LTD
摘要:This invention relates to a process for synthesis of glycerol from formaldehyde, wherein formaldehyde under substantially anhydrous condition is self-condensed in a catalytic step is dihydroxyacetone which is separated from the self-condensation catalyst and hydrogenated catalytically to glycerol. n The feature of the invention is to have less than 0.4% w/w of water in the self-condensation reaction mixture thereby improving the process to produce glycerol in commercially viable rates and yields.
