| 中文摘要: |
| 研究差示扫描量热（DSC）法评定不溶性硫黄的120 ℃热稳定性。采用DSC仪对不溶性硫黄进行多重升温速率扫描，基于Kissinger方程计算其热降解动力学参数，建立了评定不溶性硫黄120 ℃热稳定性的关系式，相关因数大于0.995，测定的相对标准偏差小于0.5%。该方法重复性优于传统方法，且操作简便，耗时少，样品量仅为传统方法的1%，同时安全性和环保性提高。 |
| 英文摘要: |
| The method to evaluate the thermal stability of insoluble sulfur at 120 ℃ by using DSC was studied. The samples were scanned at different heating rate by DSC instrument，and the kinetic parameters of thermal degradation were calculated by Kissinger equation，The equation of thermal stability at 120 ℃ was established，the correlation coefficient was greater than 0.995， and the relative standard deviation was less than 0.5%，which showed better repeatability than the traditional method.The operation of DSC evaluation method was simple and the sample consumption was only 1% of traditional method，meanwhile it was more environmentally friendly and safer. |
