Abstract
n-Hexyl gallate was synthesized from gallic acid and n-hexyl alcohol using p-toluene sulfonic acid as a catalyst.The optimal esterification conditions at 110 ℃~120 ℃ for 6 h were established as follows: gallic acid was 100 mmol,n(gallic acid) ∶n(n-hexyl alcohol) was 1.0 ∶4.5,(p-toluene) sulfonic acid was 1.0 g.The efficiency of esterification was 76.9% under the optimal conditions.
