Effect of additives on the thermal stability of sulfolane

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.
