“…The activation energy obtained for both EFH and MFH seems reasonable, i.e. in the correct range17 and consistent with that in the literature 18, 19. However, the higher activation energy value for MFH at the average temperature according to the model might be due to data correlation.…”

“…In neutral aqueous medium, Begum19 reported values of 57.6 kJ mol −1 and 47.3 kJ mol −1 for the activation energies of MFH and EFH, respectively. For the acid‐catalysed hydrolysis process, Salmi20 obtained values of 66.5 kJ mol −1 for MFH and 61 kJ mol −1 for EFH, while 44.6 kJ mol −1 was reported for EFH by Metwally and co‐workers18 using a sulfonated cation exchanger as the catalyst. Some of the fits of the model to the experimental results are given in Fig.…”

“…The hydrolysis of carboxylic acid esters is one of the most studied chemical reactions because of its importance both in chemistry and biochemistry [1][2][3][4][5][6][7][8][9]. The available catalysts used for the hydrolysis of carboxylic acid esters include homogeneous Brønsted acids and heterogeneous solid acids.…”

A carbon-based solid acid catalyst is prepared by incomplete carbonization of sulfonated naphthalene and used for the hydrolysis of carboxylic acid esters. XRD, FT-IR, TGA and acid density test are employed to characterize the structure and performance of the catalysts. The results show that the catalysts prepared under different synthesis temperature and time are amorphous carbon composed of small aromatic carbon sheets with -SO 3 H groups. The catalytic activities of catalysts for methyl acetate hydrolysis are closely related with their acid densities. The appropriate synthesis temperature and time for the catalyst are 230°C and 12 h and the acid density of catalyst under the optimized conditions can reach 4.49 mmol g -1 . The carbon-based solid acid shows higher catalytic activity than Amberlyst-15 resin as a popular hydrolysis catalyst for a series of carboxylic acid esters hydrolysis. The catalyst has good thermal stability, which can bear 250°C without decomposition. It also remains satisfactory catalytic activity for methyl acetate hydrolysis after six times recycling.
