Properties and stability

1. Avoid contact with strong oxidants.

2. Exist in oriental tobacco leaves and tobacco leaves.

3. Exist in nutmeg oil, ylang-ylang oil, etc.

4. There are two isomers, cis and trans, which have allergic effects at high concentrations. The dosage in consumer products that are not in contact with the skin should not exceed 0.5%.

Storage method

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Protect from direct sunlight. Keep container sealed and strictly prohibited from contact with air. should be kept away from oxidizer, do not store together. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.

Synthesis method

1. Obtained from the isomerization of eugenol by heating in potassium hydroxide solution. Treat eugenol or eugenol-rich essential oils with a potassium hydroxide solution to convert it into a salt. It is then heated to isomerize. After cooling, use dilute sulfuric acid to decompose the alkali metal salt, free isoeugenol, wash with water, dry, and distill under reduced pressure to obtain the finished product. Isoeugenol is found naturally in ylang ylang oil and nutmeg oil. In addition to the preparation method of eugenol isomerization, it is also prepared industrially by the synthesis method of safrole or isosafrole.

2. Heat the amyl alcohol solution of eugenol and potassium hydroxide to 200-230°C, then pour it into water, acidify it with inorganic acid, and distill the precipitated oil layer to obtain the fine product.

3. Tobacco: OR, 26; synthesis: obtained by heating eugenol and potassium solution.

Purpose

It is more elegant than eugenol for blending. It is often used as the main agent of carnation essence, and other floral essences are also widely used. It is very stable as a fragrance for cosmetics and soaps. It is also used as a food flavoring for apples, grapes, plums, apricots, raspberries or walnuts. It also has applications in dental medicine. In industry, vanillin is generally produced by oxidation of isoeugenol.
