Properties and stability

None

Storage method

This product should be kept sealed, cool and dry.

Synthesis method

Boil iso-Euegnol and acetic anhydride in a reaction tank with an air condenser for 3 hours, then evaporate the acetic acid and residual acetic anhydride to obtain a solid, which is then refined by recrystallization with ethanol.

Purpose

Because of its stable aroma, it is used in soap fragrance. It is commonly used in the preparation of sweeteners for floral and herbal flavors. It is also commonly used as a fixative for carnation flavors and French flavors, and as a colloid agent for vanillin. The aroma is similar to clove. But it has a rose scent and a sweet pod-like scent.
