p-t-부틸-α-메틸하이드로신나믹알데히드 C화학적 특성, 용도, 생산
화학적 성질
Lily aldehyde is a homolog of cyclamenaldehyde. The racemic compound is a colorless to slightly yellow liquid with a mild-floral odor, reminiscent of cyclamen and lily of the valley.The aldehyde is prepared by the same routes as cyclamenaldehyde.
Other routes start from ??-methylcinnamaldehyde. ??-Methylcinnamaldehyde (from benzaldehyde and propionaldehyde) is hydrogenated to ??-methyldihydrocinnamic alcohol.The alcohol is alkylated with tert-butyl chloride or isobutene to 4-tert-butyl-??-methyldihydrocinnamic alcohol, which is subsequently dehydrogenated to the desired aldehyde.
4-tert-Butyl-??-methyldihydrocinnamaldehyde is more stable than cyclamenaldehyde and is a popular component of flower compositions, particularly lily of the valley and linden types, because of its mild, pleasant, blossomfragrance. It is used in a wide range of perfume types, but especially in soap and detergent perfumes.
용도
In addition to its applications in the perfume and aroma industry, lilial is used mainly for the synthesis of substituted 3-(4-tert-butylphenyl)-2-methylpropylamines, a new class of substances with fungicidal properties. These compounds are effective against mildew in barley and wheat.생산 방법
Lily aldehyde is produced industrially almost solely by aldol condensation of 4-tert-butylbenzaldehyde and propionaldehyde to give 4-tert-butyl-α-methylcinnamaldehyde, which can be hydrogenated selectively on noble metal catalysts such as Pd, Rh, Pd – Pr2O3 on Al2O3, or on modified cobalt catalysts. The aldol condensation and the hydrogenation can be carried out in one step in the presence of a hydrogenation catalyst.The Friedel – Crafts reaction of 4-tertbutylbenzene with methacrolein or methacrolein diacetate proceeds in an analogous manner to the preparation of cyclamenaldehyde.
Further possibilities are the Rh-catalyzed hydroformylation of 1-(4-tert-butylphenyl)-1- methoxypropene and subsequent partial hydrogenation, the palladium salt catalyzed reaction of 4-tert-butylphenylhalide with methallylalcohol, and the dehydrogenation of 3-(4-tert-butylphenyl)-2-methylpropanol on silver catalysts.
