Properties and stability
1. Basic properties
Colorless liquid. Commercially available products are mixtures of cis and trans forms. Has anise smell. Soluble in ethanol, ether and benzene.
Storage method
Packaging in galvanized iron drums or glass bottles. Store in a cool and dry place. Keep away from fire and heat sources.
Synthesis method
Obtained from the isomerization of safrole. The reaction formula is as follows:
Take water-free safrole, heat it in KOH-anhydrous alcohol solution for isomerization, and distill it to obtain isosafrole, with a yield of up to 98%. The presence of moisture is detrimental to the isomerization reaction.
Purpose
Can be used to prepare soap fragrance.
