甲醇是一种重要的化工原料,随着它在防冻剂、浸出剂以及有机合成、电子工业等领域的应用不断增加,在精馏制备甲醇时,要获得较高质量的甲醇产品,除对其杂质指标有具体技术要求外,对它所含微量的水分还必须严格控制。

浩瀚色谱（山东）应用技术开发有限公司，采用GDX-104填充柱柱,以甲醇为溶剂、丙酮为内标物,利用毛细管柱、氢火焰离子检测器检测,测定工业用甲醇中杂质乙醇、甲酸甲酯、正丙醇、异丙醇含量。试验结果表明:本方法测定标准溶液中各杂质组分含量的相对误差为3.11%~4.51%,相对标准偏差为0.9...

Methanol is an important chemical raw material, and with its increasing applications in antifreeze, leaching agents, organic synthesis, electronics industry, and other fields, in order to obtain high-quality methanol products through distillation, in addition to specific technical requirements for its impurity indicators, strict control must also be exercised over the trace amounts of moisture it contains.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses GDX-104 packed column, methanol as solvent, acetone as internal standard, and capillary column and hydrogen flame ionization detector to detect impurities such as ethanol, methyl formate, n-propanol, and isopropanol in industrial methanol. The experimental results show that the relative error of this method for determining the content of various impurity components in the standard solution is 3.11%~4.51%, and the relative standard deviation is 0.9
