| Use | can be used in the flavor of Xiangwei, sunflower, Hawthorn, Lily, plain blue, oriental flavor, etc, most of them belong to soap flavor. In the Gulong type essence trace used as a modifier, but also for the artificial preparation of some natural essential oils such as ylang ylang, kanunga, etc., is also the raw material for the synthesis of foreign Jasmine. used for the preparation of soap flavor. |
| production method | is obtained by isomerization of safrole. The isosafrole was obtained by heating and isomerization in potassium hydroxide-anhydrous alcohol solution without water, and the yield was 98%. The presence of water is detrimental to the isomerization reaction. |
