Curcumin is subjected to the action of heat and pressure in the presence of water by a continuous or batch process to produce vanillin and other natural flavor products. The proportion of vanillin in the final product varies with the pH of the reaction mixture.

Hydrolysis of curcumin

Ketones or aldehydes containing one or more carbon-carbon double bonds and a carbonyl group conjugated with at least one double bond are hydrolyzed by the action of heat and pressure in the presence of water by a batch or continuous process. The ketone or aldehyde cleaves at the double bond conjugated with the carbonyl group to produce additional carbonyl-containing compounds.

Hydrolysis of activated olefinic ketones and aldehydes

Alpha, beta-unsaturated carbonyl compounds are hydrolyzed under alkaline conditions in the presence of water to produce additional carbonyl-containing compounds. High yields are obtained when the alkaline catalyst contains hydroxide ion and the pH is maintained in the range of about 11 to about 13.

Method of catalytically hydrolyzing alpha, beta-unsaturated carbonyl

Ketones or aldehydes containing one or more carbon-carbon double bonds and a carbonyl group conjugated with at least one double bond are hydrolyzed by the action of heat and pressure in the presence of water. The ketone or aldehyde cleaves at the double bond conjugated with the carbonyl group to produce additional carbonyl-containing compounds.
