摘要： Disclosed herein are processes for alcohol production by reducing an esterification product, such as ethyl acetate. The processes comprise esterifying acetic acid and an alcohol such as ethanol to produce an esterification product. The esterification product is reduced with hydrogen in the presence of a catalyst to obtain a crude reaction mixture comprising the alcohol, in particular ethanol, which may be separated from the crude reaction mixture. Ethyl acetate from the crude reaction mixture may be recovered as returned to assist in recovering the esterification product.

摘要： 3-Methyl-1-butanol cannot be separated from 1-pentanol by distillation or rectification because of the closeness of their boiling points. 3-Methyl-1-butanol is readily separated from 1-pentanol by azeotropic distillation. Effective agents are methylcyclohexane, methyl formate and tetrahydrofuran.

摘要： A process for separating, by distillation, a mixture consisting essentially of 3,3-dimethylacrolein and 3-methyl-3-buten-1-ol, wherein the mixture to be separated is distilled in the presence of water and glycerol, the 3,3-dimethyl-acrolein first being distilled off azeotropically with water and the 3-methyl-3-buten1-ol then being separated, as an azeotropic mixture with water, from the higher-boiling glycerol. It is also possible to isolate the 3,3-dimethylacrolein by distillation if the 3-methyl-3-buten1-ol is partially replaced by 3-methyl-2-buten-1-ol. The 3,3dimethylacrolein, which can be isolated in pure form by the process of the invention, is a valuable intermediate for the synthesis of natural substances such as citral, vitamin A and chrysanthemic acid.
