摘　　要：考察了4种不同添加剂(2,4-二叔丁基苯酚、三乙醇胺、硫代二丙酸二月桂酯、硬脂酸铜)对劣化环丁砜热稳定性的影响。在环丁砜质量100g、氮气流速95mL/min、反应温度240℃、反应时间2h的条件下,以SO_2的释放量来评价添加剂对劣化环丁砜热稳定性的影响。结果表明:4种添加剂对劣化环丁砜热稳定性的影响由大到小的顺序为:2,4-二叔丁基苯酚>三乙醇胺>硫代二丙酸二月桂酯>硬脂酸铜;当2,4-二叔丁基苯酚添加量为劣化环丁砜质量的0.12%时,SO_2的释放量为331.04mg,抑制劣化环丁砜的热分解作用效果最好。采用SPSS软件建立了对2,4-二叔丁基苯酚用量与劣化环丁砜热分解的SO_2释放量关联式,可用于实验范围内二者关系的预测。The effects of four different stabilizers （2, 4-di-tert-butylphenol, triethanolamine, dilauryl thiodipropionate and copper stearate） on the thermal stability of deteriorative sulfolane were investigated. At the conditions of sulfolane 100 g, Nz flow rate of 95 mL/min,240℃ and reaction time of 2 h, the thermal stabilities of deteriorative sulfolane were evaluated based on the release amount of SO2. The results show that the descending order of the influence of the additives on the thermal stability of deteriorative sulfolane is ： 2, 4-di-tert-butylphenol） triethanolamine, dilauryl thiodipropionate） copper stea- rate. When 2, 4-di-tert butylphenol dosage is 0.12~ of deteriorative sulfolane, the release amount of S（）2 is 331.04 mg, indicating the best effect for inhibiting thermal decomposition of sulfolane. A rela- tionship between 2, 4-di-tert-butylphenol dosage and the release amount of SO2 was established using SPSS software, which can be used for predicting the effect of the additive dosage on the thermal decom- position of sulfolane in the experimental range.
