Description

technical field

[0001] The present invention relates to an improved process for the production of alcohols from carbonyl compounds which comprises the catalytic hydrogenation of carbonyl compounds with hydrogen or a hydrogen-containing gas in the presence of shaped Raney-type hydrogenation catalysts. Specifically, the present invention includes methods for producing sugar alcohols. Compared with the currently known methods, the method can use a relatively small amount of catalyst in the process of producing alcohol, and has the same or higher yield.

[0002] According to the invention, the term carbonyl compounds refers to all organic compounds containing the =CO group, in other words also compounds containing the O=C-O group. Thus, the term carbonyl compound stands for ketones, aldehydes, carboxylic acids, carboxylates, anhydrides, esters of carboxylic acids, amides of carboxylic acids and halides of carboxylic acids.
