Abstract

The invention belongs to the field of organic synthesis in chemical industry and particularly relates to a method for preparing corresponding alcohol through carbonyl compound selective hydrogenation. According to the method, carbonyl compounds, solvents and catalysts are added into a high-pressure kettle, the pH is regulated to be in a range from 8 to 11, hydrogen gas is used as a hydrogen source, and the corresponding alcohol preparation through compound selective hydrogenation is realized at certain temperature and pressure. The method provided by the invention has the advantages that only carbonyl groups in compounds can be hydrogenised, double bonds or benzene rings contained in the compounds are not hydrogenised, the selectivity is higher than 98 percent, and the yield is higher than 95 percent.

Description

technical field

[0001] The invention belongs to the field of organic synthesis, and in particular relates to a method for selective hydrogenation of carbonyl compounds to prepare corresponding alcohols. Background technique

[0002] Alcohol compounds are widely used in medicine and daily life. For example, 1-phenylethanol is widely used in fragrance manufacturing to adjust aroma, and as the main component of rose fragrance, it is used in the synthesis of various rose oils and essential oils. Methyl isobutyl carbinol is a medium-boiling solvent with excellent performance, widely used in pesticides, medicines, cellulose, adhesives, synthetic resins and resinous automotive coatings. 1-Phenylpropanol produced by catalytic hydrogenation of propiophenone is a phenylalcohol choleretic, which has a strong choleretic effect and mild antispasmodic effect, and can be used for cholecystitis, cholelithiasis, hypercholesterolemia, biliary tract infection, etc. disease treatment.
