| 摘 要： | 介绍了不溶性硫磺总硫含量和热稳定性的测定方法,并对6种总硫含量测定方法和3种热稳定性测定方法进行分析比较.指出红外分光光度法是测定不溶性硫磺中总硫含量的最佳方法,在热稳定性的测定中推荐使用石蜡油-硅油二浴法.建议进一步完善测定方法,以适应今后对不溶性硫磺性能、质量的更高要求.

| Abstract: | Determination methods of insoluble sulphur,six for its total sulphur content and three for its thermal stability,are described and compared.The infrared spectrophotometry and paraffin oil-silicone oil two-bath method are considered as the most suitable ways to determinate total sulphur content and thermal stability of insoluble sulphur,respectively.It is proposed to make further improvement to meet more rigorous performance and quality requirements for insoluble sulphur in future. |
