摘要: 讨论了硝酸铵、硫酸铵和浓硫酸对自制甲壳素热降解和热氧化降解过程的影响。硝酸铵加速甲壳素热降解和热氧化降解过程,而硫酸铵和浓硫酸加速甲壳素热氧化降解但推迟热降解过程。3种添加剂均改变了甲壳素等温热处理后凝聚相产物。

Abstract: Thermal and thermo-oxidative degradation of chitin with ammonium nitrate,ammonium sulfate and concentrated sulfuric acid were studied.Ammonium nitrate accelerated both thermal degradation and thermo-oxidative degradation,and ammonium sulfate and concentrated sulfuric acid promoted the thermo-oxidative degradation,but delayed thermal degradation.All of these three additives changed the condensed phase products of chitin after isothermal treatment.
