Description 753-763
The Box-Behnken design-based Response Surface Methodology (RSM) has been effectively utilized to optimize
the parameters for operation in the amberlite IR 120 and sulphamic acid-catalyzed esterification of methanol and acetic acid.
The impact of three process variables, temperature, catalyst loading, and the mole ratio of methanol to acetic acid on
esterification has been evaluated. The esterification process exhibits excellent concordance between the predicted values and
the experimental values (R2 = 98.33 % and Adj-R2 = 92.08 %), which indicate the suitability of the Box-Behnken model
employed. The interaction of the parameters is also studied based on its P-value with the help of ANOVA variance. The
second-order kinetic rate equation is applied to correlate the experimental data. By employing the Arrhenius graph, the rate
constants for the backward (12.727 × 108 lit mol–1 min–1) and forward reactions (2.324 × 104 lit mol–1 min–1), as well as the
energy of activation using amberlite IR 120, have been determined. The statistical methodologies, including factorial design
and Box-Behnken response, have been employed to model the conversion of acetic acid using various regression techniques
for a quadratic equation. The result shows that the amberlite IR 120 catalyst is better than the sulphamic acid catalyst due to
the more active catalyst surface area.
