SELECTIVE LIQUID PHASE REDUCTION OF CARVONE TO CARVEOL ON Pd/Al2O3

Carveol is used in many different industries, some as an ingredient in flavors or pharmaceuticals. A method for obtaining carveol through the hydrogenation of carvones is considered. Various catalyst loading values, temperatures, and the nature of the solvent are considered. The optimal conditions for the hydrogenation of carvones under mild conditions, in various solvents and at various temperatures were determined. Conditions have been found under which complete conversion of carvones is achieved, and the maximum selectivity of the catalysts for carveol is also achieved. It has been established that selective hydrogenation of the carbonyl group of carvone is an alternative route, however, research is limited by the low yield of the target compound, so it is relevant to study the route of selective reduction of carvone to carveol.
