1-methyl-4-isopropenyl-delta(6)-cyclohexen-2-one - Production method
Carvone is found in peppermint oil, artemisia seed oil, and shiluo oil. Essential oils obtained from the fractionation of such oils. Shake together with Na2SO3 solution, separate the disulfonate generated, and decompose with sodium hydroxide to generate carvone; or dissolve the essential oil in the ethanol solution of ammonia, introduce H2S, generate adducts, and heat it with alkali to separate carvone. Another preparation method is to use alkene as raw material, react with nitrosyl chloride and hydrochloric acid, or react with amyl nitrite (or ethyl nitrite) and hydrochloric acid to form nitroso chloride. It is treated with CH3ONa or potassium hydroxide ethanol solution or pyridine or urea to remove hydrochloric acid to generate carvone oxime. Then carvone oxime is hydrolyzed with dilute sulfuric acid to obtain carvone.
