Camphene - Preparation Method

Open Data Verified Data

with high quality turpentine (mainly composed of pinene) as raw material, a-pinene was extracted by vacuum distillation, and the isomerization reaction was carried out at (135±2)℃ with hydrated titanium oxide as catalyst. The isomeric solution was subjected to reduced pressure fractionation to give Carene.

Introduction	pinene, also known as Carene, is a kind of bicyclic monoterpene compounds, isomeric products of pinene, it is a white waxy solid with a light camphor odor at room temperature. Practically insoluble in water, naturally occurring in Fir Oil, Hemlock oil, and biarya oil. Derived from the Catalytic isomerization of pinene. In a small amount of spices used in wood-based flavor. Its main use is as a synthetic camphor, synthetic sandalwood raw materials. pinene has a good effect of reducing mucus secretion, so in the treatment of respiratory tract phlegm, can be smoked or in the trachea or bronchial smears containing pinene essential oil. Although it has the property of reducing mucus secretion, but not make the mucous membrane too dry, it is a mild expectorant ingredients.
terpene compounds	pinene is an isomer of pinene, there are three optical isomers, the dl-body, the d-body and the l-body. The common one is dl-body. l-body was discovered in 1888 by goblow from fir oil, pinene is present in the essential oils of Fir Oil, Artemisia, orange flower, camphor, lavender, Acorus and turmeric, molecular formula C10H16, molecular weight of 136.24, is a colorless crystal, volatile in the air, when heated to produce flammable vapor. With similar camphor aroma. d-optical body melting point 45~46 deg C, optical rotation +104 degrees. The L-optically active substance has a melting point of 51-52 ° C. And an optical rotation of -85 °. Insoluble in water, ethanol-soluble, soluble in cyclohexane, ether and chloroform. d-Carene is found in camphor oil, ginger butter, white rose oil, lavender oil, Neroli oil. L-camphene is present in Fir Oil, Hemlock oil and biarya oil. Derived from the Catalytic isomerization of pinene. Commercially available camphenes are allowed to contain-20% of a tricyclic terpene. Melting point 41-45 deg C, content is greater than or equal to 80%. In a small amount of spices used in wood-based flavor. Its main use is as a synthetic camphor, synthetic sandalwood raw materials. S. FEMA2903; FDA approved for use in food. prepared from pinene by isomerization at 135±2 ℃ using hydrated titanium oxide as catalyst, alternatively, L-Carene and d-Carene are prepared from borneol-based chlorides by heating together with a base in the presence of rosin olefin sulfonic acid. The process flow chart of preparing pinene is as follows: pinene has little use in flavoring, but only a small amount is used in daily chemical essence. It is mainly used as an important raw material for the synthesis of borneol, toxaphene, isoprenic thiocyanate acetate, isoprenyl acetate, camphor and sandalwood flavor. pinene is also an important spice, It is the edible spice permitted by China's regulations GB2760-1996, and it is also an important raw material for spices, synthetic camphor and borneol. In acidic medium, it condenses and hydrogenates with guaiacol, can be prepared from sandalwood or sandalwood odor of other perfume compounds; Can also be used for the preparation of soap and deodorant flavor; Pesticide raw materials, preparation of toxaphene.
Source	pinene is present in essential oils such as fir oil, Artemisia annua, neroli, camphor, lavender, Acorus and turmeric.
Application	pinene is mainly used as a raw material for organic synthesis, which can be used for the synthesis of camphor, spices, pesticides, isosyl thiocyanate acetate, isosyl acetate, toxaphene, etc. In addition, it is used as a chemical reagent in analytical chemistry.

Use	for the synthesis of spices, pesticides, camphor, etc. For the synthesis of camphor, perfume (such as isobornyl acetate), insecticide (such as toxaphene, isoprenyl thiocyanate), borneol, isoprenyl acetate, etc. for the synthesis of camphor, spices (isobornyl acetate), pesticides (such as toxaphene, thiocyanate), borneol, isoprenyl acetate
production method	with high quality turpentine (mainly composed of pinene) as raw material, after vacuum distillation, the fraction at 70-80 °c (66.5-69.2kPa) was collected to obtain α-pinene, which was then isomerized at 135-140 °c using hydrated titanium oxide as a catalyst, and then subjected to reduced pressure fractionation to obtain a final product of camphene. The content of industrial products is greater than or equal to 95%, and the melting point is above 45. Each ton of product consumption of high-grade turpentine 1500kg.
