There are two kinds of isomers of the right and the left. Found in a variety of essential oils, especially lemon oil, orange seed oil, tarsaria oil, rose oil, bergamot oil. It is a colorless flammable liquid at room temperature and has a good smell of lemon.
This product is widely found in natural plant essential oils. Among them, the main ones containing dextrose are orange oil, lemon oil, orange oil, camphor white oil and so on. Containing levorotatory body of peppermint oil and so on. Containing racemate of neroli oil, Fir Oil and camphor white oil. In the manufacture of this product, respectively from the above essential oils for fractionation, can also be extracted from the general essential oil terpene, or in the process of processing camphor oil and synthetic camphor, as a by-product. The resulting dipentene was purified by distillation to obtain rostoene. Turpentine oil is used as the raw material, and a-pinene is cut out by fractionation, which is obtained by isomerization to produce pinene and then fractionation. The by-product of camphene is dipentene. In addition, dipentene can also be produced by hydration of turpentine to terpineol.
used as a solvent for enamel, false paint, various oleoresin, resin wax, Metal Drier; Used in the manufacture of synthetic resin; As a perfume to prepare orange flower oil and orange oil, can also be made into a substitute for lemon essential oil; Can also be synthesized carvone and so on. Used as oil dispersants, rubber additives, wetting agents.
