多环烯烃——柏木烯经乙酰化生成乙酰基柏木烯。乙酰基柏木烯是一种新型香料,它在调香过程中起着修饰、协调,保香作用。 本文介绍柏木烯在多聚磷酸催化下,用乙酸酐酰化合成乙酰基柏木烯。 产物的IR谱显示出碳-碳双键与羰基共轭峰的特征。同样,产物的UV谱亦显示出碳-碳双键与羰基共轭吸收峰向长波方向移动的特点。 Polycycloolefin-cedrene is acetylated to acetyl cedryl. Acetyl cedrene is a new type of perfume, which plays a decorative, coordinating and fragrant aroma in the fragrance process. This article describes the cedrene in the polymerization of polyphosphoric acid, acetic anhydride acylation acetylene cedrene. The IR spectrum of the product shows the characteristic of the carbon-carbon double bond and carbonyl conjugate peak. Similarly, the UV spectrum of the product also shows the shift of the conjugate absorption peak of carbon-carbon double bond and carbonyl to long-wave direction.
