Abstract Methyl esterification of salicylic acid catalyzed by strong acidic cation exchange resin NKC-9 was carried out on an intensified fixed bed reactor (IFBR) to investigate the effects of different parameters and the results showed that the optimal conditions were as follows: circulation speed is 1.5 L· h−1, catalyst loading is 20 %, initial mole ratio of salicylic acid and methanol is 1:6 and reaction temperature is 343.15 K. The thermodynamics for the methyl esterification of salicylic acid have been studied to obtain the equilibrium constant from the experimental data at different temperature. PH, E-R and LHHW models were used to correlate the kinetic data in the temperature range from 328.15 to 348.15 K. The calculated value is in good agreement with experimental value, indicating that all the models can be used to accurately describe the process of the methyl esterification of salicylic acid.

Fatty acid methyl ester biodiesel was successfully synthesized by the esterification of the palm oil deodorizer distillate (PODD) with methanol, catalyzed by the strongly acidic cation-exchange resin as solid acid in a self-made fixed bed reactor. The reaction condition was optimized, and the product could basically reach both national standard and Germany standard.
