Abstract
Abstract Described is a process for preparing hydrogenated derivatives of 2,6,6-trimethyl cyclohexene derivatives by means of treating said derivatives with hydrogen in the presence of a supported palladium catalyst such as palladium-on-calcium carbonate or palladium-on-barium sulfate in the presence of a quinoline activator. The resulting products are useful for their organoleptic properties as foodstuff flavorants and flavor enhancers, perfume composition ingredients, perfumed article ingredients and tobacco flavorants and flavor enhancers.
