Introduction | isobornyl acetate is colorless crystalline powder with rosin camphor odor. |
preparation | isobornyl acetate can be obtained from the addition of one molecule of acetic acid and simultaneous molecular rearrangement of camphene catalyzed by ENE sulfuric acid. |
assay | was determined by method one in the ester determination method (OT-18). The amount of the sample was 1G. The equivalence factor (e) in the calculation is taken as 98.15. Or according to Gas chromatography (GT-10-4) using non-polar column method. |
toxicity | GRAS(FEMA). |
usage limit | FEMA(mg/kg): Soft drink 9.6; Cold drink 12; Candy 3.9; Baked goods 9.5; pudding 70. Moderate limits (FDA § 172.515,2000). |
Use | for the fragrance industry, also used as a raw material for the synthesis of camphor GB 2760-96 is specified as a permitted flavor. Mainly used for berries and a variety of fruit-type flavor (minimal amount). spices. Commonly used as daily chemicals, such as soap, powder, toilet water, air spray, etc. flavoring agent. |
production method | reaction of camphor with glacial acetic acid in the presence of sulfuric acid; Or, glacial acetic acid is obtained by heating to 40-50 °c in the presence of a small amount of sulfuric acid. In industry, turpentine is generally used as a raw material. First, it is fractionated, and the fraction with boiling range of 156-161 ℃ (mainly α-pinene) is isomerized to form pinene, which is then reacted with glacial acetic acid to form isobornyl acetate, the product was obtained by washing with water and rectification. Industrial products contain isobornyl acetate ≥ 97%. The free acid contains less than 0.1% isobornyl acetate. Consumption of 98.5% glacial acetic acid and 1070kg turpentine per ton of product. obtained by co-heating (50~60 ° C.) of Carene, glacial acetic acid and sulfuric acid, separating with water and rectification. Acetylated from isobornyl alcohol. |
