摘要
将UOP 660气相色谱法测定水或烃中环丁砜的方法进行了改进,采用开口管柱代替原方法中的填充柱,色谱操作条件也作了相应的改变。改进的方法与原方法比较具有基线稳定,水的干扰峰不拖尾,水峰和环丁砜的峰完全分开等优点。该新方法准确度高,重复性好,完全能满足生产的需要,具有较大的实用性。
Uop method 660 of sulfolane in water or hydrocarbons by chromatography was impoved, packed column used 6-riginallly was replaced with capilary column and condition of chromatograph was modificed. Baseline of chromatograph was sta-ble.Water was seperated from sulfolane by capilary thoroughly,having no influence on determination of content of sulfolane.The method has the character of high acuracy,good repeatability and great value of use in practice.
