Molecular formula : C12H20O2 MW : 196.29 CAS No. :125-12-2
nature : a colorless liquid. 29 ° C melting point, boiling point, 220-224 ° C and relative density of 0.978 (20 / 4 ° C), the refractive index 1.463-1.465. Soluble three times the size of 70% ethanol and 95% ethanol, ethyl ether immiscibility, do not dissolve in water and glycerol. With Acetate have the same aroma, and more comfortable.
Preparation : In the presence of sulfuric acid and naphthalene acetic acid with reaction; Or Isoborneol, a small amount of acetic acid in the presence of sulfuric acid heated to 40-50 ° C derived. Industry generally turpentine for raw materials, conduct fractionation, boil-cut 156-161 ° C for distillate (mainly alpha-pinene) isomerization, generating Camphene, with acetic acid produced by the reaction Isoborneol acid ester, washed, distillation derived products. Industrial products containing acid ester Isoborneol �97%. Free acid-containing acid ester Isoborneol less than 0.1%. Ton products consume 98.5% acetic acid feeding trial for 47 days, turpentine 1070kg.
purposes : spices. Chemicals used in Japan, such as soap, powder, fancy, air spray the flavoring agent.
