Abstract: Isomeric esterification of camphene with glacial acetic acid catalyzed by Lewis acids was studied to produce isobornyl acetate.And the suitable esterification conditions were examined and optimized as following:FeCl3 as catalyst,catalyst dosage 10%(mass ratio of camphene),reaction temperature 25℃,reaction time 2 h,n(camphene):n(acetic acid)1:3.As results,using 94.9% camphene (the total of camphene 84.8% and tricyclene 10.1%) as raw material,the conversion rate of camphene was nearly 99%,the selectivity of isobornyl acetate reached 94%,and the yield of isobornyl acetate reached more than 88% in the product.

Key words: Lewis acid, ferric trichloride, camphene, acetic acid, isobornyl acetate
