Properties and stability

1. Use and store according to specifications. It will not decompose and avoid contact with oxides.

2. Found in tobacco leaves.

3. (+)-borneol naturally occurs in lavender oil, scented perilla oil, rosemary oil and some camphor oils. (-)-borneol is found in essential oils such as coriander oil, citronella oil, and turpentine.

4. It has certain toxicity, irritation and allergic reactions.

Storage method

Stored in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. The packaging is sealed. They should be stored separately from acids and food chemicals, and avoid mixed storage. Suitable materials should be available in the storage area to contain spills.

Synthesis method

1. Prepared by dissolving camphor in ethanol and reducing it with metallic sodium or with new ecological hydrogen.
2. Synthesis: α-pinene is first treated with hydrogen chloride, and after molecular rearrangement, it generates chloroborneol. After treatment with alkali, it becomes pinene, and then it is added with acetic acid to transform into isoacetic acid. Bornyl ester is obtained by saponification and hydrolysis of isobornyl acetate and its isoform structure; method two: first convert α-pinene into chloroborneol, and then undergo Grignard reaction, oxidation, and hydrolysis. Made into borneol.


1. GB 2760-1996 stipulates that edible spices are allowed to be used. Mainly used for preparing mint, white lemon and nut flavors. 2. Used as biochemical reagents and also in the pharmaceutical industry. 3. Widely used in the preparation of rosemary, lavender and other flavors, and used in combination In pharmaceuticals, etc. 4. It is also mainly used in fragrances such as cleaners, detergents, insect repellents, and inks. 5. Used as a special additive for therapeutic cosmetics. Used in toilet water, etc.
