use | is widely used in flavor formulas for various purposes, and is also used as an agent to increase freshness. As a body fragrance, it is often used in lily, lilac, lily of the valley and other flavors. It is also an important spice in magnolia, gardenia, narcissus, apple blossom, fragrant Wei and pine needle flavor. It is the main component in many soap, daily chemical products and disinfectant flavors. Pure products (mainly nail body) can be used as edible essence. the main agent of lilac flavor, strong alkali resistance, suitable for soap essence, its acetate has citron and lavender aroma, used for the preparation of essence. It is also used in medicine, pesticide, plastic, soap, ink, instrument and telecommunications industry. It is an excellent solvent for color on glassware. terpineol (Alpha-Terpineol) has lilac flavor. its formate and acetate can be used for essence preparation, advanced solvent and deodorant. It is also used in the medicine, pesticide, plastic, soap, and ink industries. It is also a solvent for colors on glassware. used to prepare essence, advanced solvent and deodorant used to blend soap, soap and cosmetic spices, can be used to blend essence of lilac, etc. used in pharmaceutical industry, also used as perfume, solvent and ink, etc. |
production method | turpentine is treated with 23% dilute sulfuric acid to convert the main component α-pinene into terpene diol monohydrate. this intermediate is dehydrated to obtain crude terpene alcohol, which is then fractionated, refined and refined. Raw material consumption quota: turpentine 1730kg/t, sulfuric acid (98%)650kg/t, caustic soda 160kg/t. |
