ABSTRACT
In the present study, n-octyl acetate was synthesized using silica sulphuric acid catalyst by esterification reaction of acetic acid and n-octanol. The esterification reaction was performed in the batch reactor. The impact of various reaction parameters viz., mole ratio (1:1-1:3 acid to alcohol), catalyst mass (2-8 wt%), speed of agitation (200-600 rpm), and temperature (328-348 K) on the conversion was studied and optimized. The result showed that the conversion of acetic acid was 92.72% under the condition of mole ratio (1:2 acid to octanol), catalyst mass (6 wt%), speed of agitation (400 rpm), and reaction temperature (348 K). The activation energy was computed as 29.82 KJ·mol-1. The thermodynamic parameters were evaluated at different temperatures. The silica sulphuric acid catalyst shows agreeable activity and a reusability study shows it could be used up to four recycles.
