摘要： Polyhydric alcohols are prepared by the aldol condensation of an aldehyde having 1 to 3 hydrogens on the alpha-carbon atom with formaldehyde in the presence of sodium carbonate and the subsequent crossed Cannizzaro reaction wherein the aldol condensation product is reacted with additional formaldehyde and sodium carbonate to form a polyhydric alcohol.

摘要： The present invention relates to a process for the manufacture of 2,2-disubstituted propiolactones via the pyrolysis of methylene diisoalkylate in the vapor phase over a fixed bed catalyst system. The reaction of the invention is as follows: ##SPC1##Wherein R is alkyl of from 1 to 4 carbon atoms and R.sup.1 is alkyl of from 1 to 4 carbon atoms or phenyl. The catalyst comprises an oxide of a metal selected from the group Ag, U, Zn, Ti, Zr, Th, Ta, Nb, Mo, W, and Sn on a suitable support. A preferred catalyst is the metal oxide-silica gel complex which results from heating the calcined residue of a salt of a metal selected from the group consisting of Ta, Ti, Nb and Zr supported upon a silica gel in the presence of nitrogen and steam at a temperature of from about 650.degree. C. to about 1000.degree. C. The process is operable at temperatures from about 240.degree. C. to about 360.degree. C. with contact times ranging from about 0.1 second to about 30.0 seconds. The gaseous ester feed may, if desired, be diluted with an inert gas such as nitrogen and the reactor may be run at atmospheric, or superatmospheric pressure.

摘要： An improved process for the production of aliphatic nitriles having two to six carbon atoms by the reaction of an aliphatic carboxylic acid with ammonia in the presence of a catalyst followed by effluent distillation. The improvement lies in the addition of a portion of the aliphatic carboxylic acid after the reactor but before distillation whereby ammonium carboxylate formed in the reaction and dissociated by distillation is reformed to the carboxylate thus preventing the escape of dissociated ammonia and whereby the aliphatic carboxylic acid portion is recycled to the reaction.

摘要翻译： 通过在催化剂存在下通过脂族羧酸与氨的反应，然后进行流出物蒸馏，制备具有2-6个碳原子的脂族腈的改进方法。 改进之处在于在反应器之后但在蒸馏之前加入一部分脂族羧酸，由此在反应中形成的羧酸铵和通过蒸馏解离的羧酸盐重整成羧酸盐，从而防止解离的氨逸出，由此脂族羧酸部分 被回收到反应。
