Abstract

Polyhydric alcohols are produced by treating an aqueous solution of a saccharide with hydrogen in the presence of a ruthenium-containing catalyst. The catalyst may be, for example, ruthenium metal; its sesquioxide, dioxide or tetroxide; salts of ruthenium such as sodium or barium perruthenite, magnesium, strontium, calcium, silver, barium, potassium or sodium ruthenate; sodium or potassium perruthenate; ruthenium dichloride, trichloride, tetrachloride or pentafluoride; ruthenium disulphide; or potassium chloro-perruthenate. The preferred temperature range is from 50 DEG to 400 DEG C. and the preferred pressure range is from 100 to 1500 p.s.i.g. The catalyst metal may be used in conjunction with a support such as carbon, alumina, silica, kieselguhr, synthetic gel or diatomaceous earth. Another metal of the platinum group, e.g. platinum or palladium, or its oxide, may also be present. The process may be carried out batchwise or continuously. Monosaccharides and polysaccharides may be treated according to the process of the invention. In the examples: (a) dextrose is hydrogenated using a catalyst consisting of ruthenium metal on carbon to give sorbitol; (b) dextrose is hydrogenated using (a) a ruthenium on alumina catalyst and (b) a catalyst consisting of ruthenium and platinum or carbon or alumina supports; (c) sucrose, levulose, maltose and lactose are hydrogenated in the presence of a ruthenium on carbon or a combination of ruthenium and palladium on carbon; sucrose and lactose are hydrolysed and hydrogenated to give the corresponding hexitols, maltose gives maltitol and levulose is hydrogenated directly to the corresponding hexitol; and (d) dextrose is hydrogenated in the presence of ruthenium oxide.
