Abstract

PURPOSE: When cinnamic acid is produced by oxidizing cinnamaldehyde with molecular oxygen, silver adsorbed on activated carbon is used as a catalyst, whereby cinnamic acid of high purity used as a starting material of perfume is produced in high yield with almost no formaton of resinous substances.
CONSTITUTION: Using silver adsorbed on activated carbon as a catalyst, cinnamaldehyde is oxidized with molecular oxygen to produce purely white cinnamic acid giving more than 99% purity without recrystallization in a yield as high as 97W100% theoretically. Further, no resinous substance is formed to keep the catalyst clean and prolong the catalyst life almost permanently. The catalyst is prepared, e.g., by dissolving a water-soluble silver salt such as silver nitrate in water, adding a fine powder of active carbon and a water-soluble aldehyde reducing agent such as formaldehyde to the silver solution and dropping a conc. aqueous solution of caustic alkali to the mixture at 0±5°C. The content of silver is 30W300wt% based on the activated carbon.
