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%.

权利人:INST SUPERIOR TECNICO
摘要:The present invention relates to a process for the synthesis of polyesters comprising reacting a dicarboxylic acid monomer with a dialcohol monomer, in an equimolar concentration in the range of 0.2 M to 1.0 M, in the presence of a biocatalyst, in an aqueous polymerization medium, at a temperature in the range of 25-45°C, the biocatalyst being in the form of an enzyme immobilized on a solid support. The present invention further provides a copolymer obtained by the invention process.

摘要:The invention relates to a multi-stage process for the continuous, phosgene-free preparation of (cyclo)aliphatic diisocyanates that comprises the conversion of (cyclo)aliphatic diamines into the corresponding (cyclo)alkylene biscarbamates and the thermal cleaving of the latter into the (cyclo)alkylene diisocyanates and alcohol. The urea used in accordance with the invention and also the urea employed for the preparation of urea equivalents (e.g. alkyl carbonates, alkyl carbamates) as a possible precursor for the synthesis of the (cyclo)aliphatic biscarbamates is unconditioned.
