| abstract | 1,227,601. Production of alcohols. IMPERIAL CHEMICAL INDUSTRIES Ltd. 12 June, 1968 [3 July, 1967], No. 30578/67. Heading C2C. Alcohols, preferably C 1-12 saturated aliphatic or aryl and alkaryl alcohols, are produced by reduction of the corresponding aldehyde with formic acid, preferably present in 10-500% excess in a liquid medium containing in solution a complex of Ir, Pt, Ru or Os. The preferred complexes have the formula IrH x A 3-x Z m L n in which A is an anion, Z is a tertiary phosphine or arsine group, L is a CO group or a nitrogen containing organic base, x is 0 or 1-3 and m and n are integers such that m + n = 2 or 3, m is at least 1 and n may be 0, e.g. IrH 3 (PR 3 )p wherein p is 2 or 3 and R is alkyl or aryl, perferably phenyl or alkylphenyl. The reaction may be carried out in the presence of free tertiary phosphine, temperatures may be from 50- 120‹ C. and the pressure may be 1 atmosphere. A solvent may be used, e.g. a C 1-5 saturated aliphatic carboxylic acid in which case the product alcohol is normally at least partially esterified. The catalyst may be present in 0À05-0À5% by weight expressed as metal based on the weight of the liquid medium and aldehydes may be selectively reduced in the presence of a ketone or of a nitro- or nitrile group. The examples describe the conversion of butyraldehyde to butanol and butyl acetate, isobutyraldehyde to butanol, crotonaldehyde to butanol and butyl acetate, p-nitrobenzaldehyde to p-nitrobenzyl alcohol and p-nitrobenzylacetate and benzaldehyde to benzyl alcohol. Butyraldehyde is produced as a biproduct in the conversion of crotonaldehyde to butanol and butylacetate . |
