标题:高温水(wet):保护基团选择性水解中的反应物,催化剂和溶剂
摘要:高温水(wet)在反应过程中可以同时充当反应物,溶剂和催化剂.Wet已成功用于去除保护基,从而减少了对添加强酸/碱,中和和消除废盐的需求.水介导去除几个常见保护基的方案,例如从125至150oc的氨基甲酸叔丁酯(n-Boc),在275oc的乙酰胺(n-Ac)和乙酸酯(o报道了不同型号的芳基化合物在250oc下的-Ac).另外,通过简单地调节温度,证明了高产率和在另一个保护基存在下一个保护基的选择性脱保护.为了进一步了解反应过程,还讨论了几种反应物的水溶性,与这些反应有关的动力学和机理.

标 题 :Preparation of disperse azo dyestuffs in the presence of alkoxylated acetylenic diols
发明人：DADO GREGORY PAUL
权利人:AIR PROD & CHEM
摘要:The use of alkoxylated acetylenic diol surfactants in the aqueous synthesis of disperse azo dyes provides a simple process for improving filtration properties of dyestuff. The surfactants may be added prior to the coupling step of the synthesis or prior to heat treatment of the dye slurry. Advantages that are realized by incorporation of the surfactants into the synthesis include decreased filtration time, increased solid content in filter cake, improved washing properties of filter cake, and increased dye yield. In addition, for azo dyes that are synthesized as non-heat-stable crystal modifications, the presence of alkoxylated acetylenic diol surfactants in the dye slurry is effective in promoting the conversion of the dye to the desired thermally stable crystal modification.

摘要:A method for synthesizing a polyester comprises reacting a diester and a dialcohol at approximately ambient temperature in the presence of an enzyme catalyst, preferably a lipase comprising porcine pancreatic lipase. The method is particularly adapted for enantioselective polymerization resulting in an optically active polyester. The polyesters preferably exhibit a weight average molecular weight, Mw, as measured by gel permeation chromatography of at least about 3000.
