Introduction

Isobornyl acetate is a colorless crystalline powder with the smell of rosin and camphor.

Colorless crystalline powder. Has a rosin camphor smell. Soluble in ethanol and ether, almost insoluble in glycerol and water.

●  Used in perfume industry, also used as raw material for synthesizing camphor

●  GB 2760-96 stipulates that the edible spices are allowed to be used. Mainly used for berries and various fruit flavors (in a very small amount).

●  spices. It is often used as a flavoring agent for daily chemicals, such as soap, talcum powder, toilet water, air spray, etc.

●  It is obtained by reacting glacial acetic acid with camphor in the presence of sulfuric acid; or by heating isoborneol and glacial acetic acid to 40-50°C in the presence of a small amount of sulfuric acid. In industry, turpentine is generally used as the raw material, which is first fractionated, and the fraction with a boiling range of 156-161 °C (mainly α-pinene) is isomerized to generate camphene, which is then reacted with glacial acetic acid to generate isoborneol acetate. , After washing and rectifying, the finished product is obtained. Industrial products contain isoborneol acetate ≥97%. The free acid contains less than 0.1% isobornyl acetate. Each ton of product consumes 400kg of 98.5% glacial acetic acid and 1070kg of turpentine.

●  It is obtained from camphene, glacial acetic acid and sulfuric acid after co-heating (50-60 ℃), adding water for isolation and rectification.Acetylated from isoborneol.
