【Abstract】 The lifetime of azithromycin was studied by isothermal thermogravimetry(TG)method.The lifetime equations at various weightloss ratio of 5%,7% and 10% were deduced as lg τ = 2083.96 / T -4.1299, lg τ =4588.797/ T -8.9821 and lg τ =5074.97 /T -9.7668,respectively.The activation energy of thermal decomposition reaction in the second step obtained by using the method of Kinssinger is 126.43kJ/mol.更多还原
