  • Synthesis of carbonyl compounds
    Patent number: 4820875
    Abstract: In a process for vapour-phase synthesis of carbonyl compounds from alcohols a mixture of the alcohol and air or oxygen is passed over a silver catalyst. The concentration of alcohol:air or alcohol:oxygen is below the explosive limits. The process is conducted as a temperature between 200.degree. and 450.degree. C. Previously the production of carbonyl compounds required a temperature of 450.degree.-700.degree. C. which necessitated the use of heat exchangers using fused salt baths. The silver catalyst may be supported.
