几种添加剂对环丁砜热稳定性的影响
Effect of Several Additives on the Thermal Stability of Sulfolane
摘要
Abstract
Physical and chemical properties and poor quality of sulfolane was analysed, and the effect of several additives on the thermal stability of sulfolane was studied. An optimized experiment condition, water-vapour absorption, nitrogen protection, 220 ℃ and 6 h were set. Four amine alcohols were used as additives. The thermal stability of sulfolane was evaluated indirectly by the generation amount of BaSO4, and finally by the content of released SO2. The less content of released SO2 indicated the better effect of additives on restraining sulfolane thermal decomposition. The different quantity of addition of every additive are investigated, certain effect of all four additives can be observed, in which, quantity of addition of HW-D-01 at 0. 04% lead to a best effect on thermal stability of sulfolane.关键词
