Function/use

【 Use 1 】

For synthetic spices

【 Use 2 】

GB 2760--1996 specifies the permissible use of edible spices. It is mainly used to prepare assorted fruit and citrus flavors.

【 Use 3 】

Hydrocarbon synthetic fragrance. Mainly used in cologne and deodorant. It is also an important raw material for synthetic terpenes.

Preparation method

1. Obtained by distillation and separation of the distillate of cotinus leaves or rububu leaves.

2. Tobacco: FC, 18; FC, 40.

3. Synthesis: β-pinene can be pyrolyzed in a metal tube at high temperature, or prepared by dimerization with raw isoprene in the presence of catalyst.
