DTA

TG

DTG techniques were used to study the thermal oxidation degradation and kinetics of triprolidine hydrochloride(C 19 H 22 N 2·HCl·H 2O) in air.It has been found that the thermal oxidation degradation of medicine C 19 H 22 N 2·HCl·H 2O is of five steps.Treated with Coats Redfern equation

the apparent degradation reaction orders of medicine C 19 H 22 N 2·HCl·H 2O are 1 1

the reactive energies are 66.5
