Medicinal grade turpentine cas8006-64-2 uses

Medicinal grade turpentine cas8006-64-2 use turpentine, is a kind of essential oil, it is an important industrial raw material
.
Turpentine is a liquid extracted from the resin of the conifers by distillation or other methods, and the main component is terpenes
.
Turpentine can be mixed with chloroform, ethyl or acetic acid in any proportion, but is insoluble in water
.
Turpentine is a high flash point combustible liquid, volatile, chemical properties 1, oxidation reaction turpentine is easy to absorb oxygen in the air and be oxidized, when there is moisture, oxidation into a yellow viscous substance, so turpentine can not be exposed to the air for a long time
.
2, isomerization reaction a-pinene under the action of the catalyst metatitanic acid, can occur isomerization reaction, the formation of camphor, campene is an important intermediate, through which it can synthesize a series of substances, such as the synthesis of camphor
.
3.
The addition reaction a-pinene can add to the water under the action of the catalyst sulfuric acid to generate hydrated terpene glycol, and then remove a molecular water, which can obtain
terpineol.
4.
The esterification reaction adds organic acids to the double bond of a-pinene to form esters, such as isorylocyl oxalate
.
Using this reaction, ice chips can be synthesized
.
5, hydrogenation reaction of pinene under the action of the catalyst, can be added to the double bond hydrogen atoms, and then after a series of reactions, can be prepared linalool, it is an important fragrance
.
6.
The polymerization reaction a-pinene and b-pinene can be polymerized by the catalyst in the Sui solvent, so that the molecules are connected to each other, and after the solvent is steamed, the terpene resin
is obtained.
This product is a volatile oil
that is infiltrated from several species of plants in the genus Pinaceae, and is extracted by distillation or other methods.
【Properties】This product is a clear liquid from colorless to yellowish; Stinky specific
.
After prolonged storage or exposure to the air, the odor gradually increases and the color gradually turns yellow
.
This product is flammable and produces thick smoke
when burned.
This product is easily soluble in ethanol, and tri, B or glacial acetic acid can be arbitrarily miscible and insoluble
in water.
