- Abstract:
- A novel catalyst, PW-SBA-15, was prepared by post-synthesis method, and PW-SBA-15 was characterized to obtain its nitrogen adsorption isotherm. w(H2O2)=30% was used as oxidant, cyclohexene was oxidized by a pot boiling method to obtain the target product adipic acid, and its IR spectra were determined by Fourier infrared spectrometer, and the standard molar combustion enthalpy of adipic acid was determined by XRY-1C microcomputer oxygen bomb calorimeter as -2801.0 kJ·mol-1, and the standard molar enthalpy of adipic acid was calculated to be -989.32 kJ·mol-1. At the same time, the melting point and melting enthalpy of adipic acid were determined by DTG-60 differential thermal-thermogravimetric analyzer, which provided basic data for industrial production and design.
