| 摘 要： | 考察了加热温度和加热时间及添加剂对环丁砜热稳定性的影响,以SO2的释放量作为环丁砜热稳定性的最终评价指标。结果表明,在水气吸收、氮气保护2、30℃加热2 h的实验条件下,添加剂E的使用效果最好,加入量为环丁砜的0.04%时,环丁砜分解产生的硫酸钡沉淀量与SO2释放量最少,释放量为10.99 mg。

| Abstract: | Investigated additives,heating temperature and time on the thermal stability of sulfolane,and used the content of released SO2 as the final evaluation of the sulfolane thermal stability.The results showed that under the experimental conditions of the absorption in water vapor,nitrogen protection,230 ℃ heating 2 h,the additives E has the best effect.When add the amount of 0.04% of the sulfolane,the sulfolane decomposition of BaSO4 and emission SO2 least,the emission is 10.99 mg. |
