Storage method
Packed in galvanized iron drums or glass bottles. Store in a cool and dry place. Keep away from fire and heat sources
Synthesis method
1. Natural sassafras mainly exists in natural plant essential oils such as sassafras oil, camphor oil, South American Brazilian sassafras oil, and North American sassafras oil. It can be isolated from the above essential oils.
2.Obtained from the isomerization of safrole.
Purpose
1. Safrole can eliminate the smell of grease in soap and is often used to prepare soap flavors.
2. Mainly used for the synthesis of jasmonaldehyde and vanillin.
