浩瀚醇醚产品中微量环氧乙烷测定填充柱Porapak QS

醇醚产品是一类新型的重要工业产品,尤其在表面活性剂工业中占有重要地位。随着我国洗涤剂行业的发展,也必将对醇醚系列产品的发展起到积极的推动作用。醇醚类产品主要合成方法是采用高碳醇或酸与环氧乙烷乙氧基化反应而制得。环氧乙烷是一种有毒、易燃、易爆物质。

浩瀚色谱（山东）应用技术开发有限公司研发出Porapak QS不锈钢填充柱，测定醇醚产品中微量环氧乙烷，该方法加标回收率在88.3%~104.7%,相对标准偏差在0.66%~3.94%。应用此法杂质干扰少,对醇醚产品中微量环氧乙烷在0.4~25 mg/kg线性关系良好(γ0.998),该方法操作简便,准确性高,重复性好,在应用中取得很好的效果。

Alcohol ether products are a new type of important industrial products, especially occupy an important position in the surfactant industry. With the development of my country's detergent industry, it will also play a positive role in promoting the development of alcohol ether products. The main synthesis method of alcohol ether products is the ethoxylation reaction of higher alcohol or acid with ethylene oxide. Ethylene oxide is a toxic, flammable, and explosive substance.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. developed the Porapak QS stainless steel packed column to determine trace amounts of ethylene oxide in alcohol ether products. The recovery rate of this method is 88.3%~104.7%, and the relative standard deviation is 0.66%~3.94. %. The application of this method has less impurity interference, and has a good linear relationship with the trace ethylene oxide in the alcohol ether product at 0.4-25 mg/kg (γ0.998). This method is simple to operate, high in accuracy, and good in repeatability. effective.
