Properties and stability

1. Found in essential oils such as lavender, cardamom, eucalyptus, and bitter orange, usually acetic acid A mixture of α-terpineol and early terpineol acetate, mainly α-terpineol acetate.

2. Exist in flue-cured tobacco leaves.

Storage method

Packaging in galvanized iron drums. Store in a cool and dry place. Keep away from fire and heat sources. Do not store together with flammable and explosive materials.

Synthesis method

1. It is mainly produced using turpentine as raw material.

2.Add the mixed aqueous solution of acetic acid and sulfuric acid into turpentine, place it at 30-40°C for several hours, and then allow the oil layer to separate out. After separation, it can be obtained by neutralization and distillation under reduced pressure. It can also be obtained by reacting terpineol, acetic anhydride and anhydrous sodium acetate, followed by neutralization, washing, separation and distillation.

3. Tobacco: FC, 18.

Purpose

1. Mainly used for preparing food flavor raw materials.

2.Mainly used in lavender, fragrant rose, cologne, pine needles, fruity fragrances and other daily fragrances; also used in grapefruit, citrus, It can be used in food flavors such as orange, peach, apricot, cherry, lemon, spicy and meaty flavors; it can also be used to add cardamom, sweet oregano, thyme and other flavoring essential oils to enhance Enhances its spicy aroma. The dosage used in chewing gum is 14~260mg/kg; in meat, it is 1.7~40mg /kg; condiments 15mg/kg; baked goods 15 mg/kg; 6.3mg/kg in candies; 3.5mg/ in soft drinks kg; 3.2mg/kg in cold drinks.
