Industrial methylal purity and impurity content analysis special capillary column

Methylal (Methylal) chemical name is Di-methoxymethane (Di-methoxymethane, DMM), has excellent physical and chemical properties, that is, good solubility, compatibility with water, and is widely used as chemical intermediates and solvents. At the same time, because of its high oxygen content and no C-C bond in its molecular structure, it can be used as a transportation fuel and fuel additive, as well as a mobile hydrogen energy source for fuel cells.

Methylal is an important derivative of natural gas and coal chemical industry, and has a wide range of applications in the fields of chemical intermediates, solvents, fuels and fuel additives. In industrial production, methylal is mainly produced by the reactive distillation of methanol and formaldehyde. In addition, a new process for selective oxidation of methanol and dimethyl ether to produce methylal is also under development. The process of refining and purifying methylal has also been further researched and developed.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. is advancing with the times, guided by scientific development, under the leadership of manager Wang Xiaoying, relying on Xiangying Institute of Analysis Technology, Chromatography Engineering Institute, Analysis and Testing Center, 3 scientific research The unit has developed a special capillary column for the analysis of industrial methylal purity and its impurity content. Gas chromatography is used to analyze methylal and its impurity content, and it is quantified by the normalization method with correction factor. The method is simple, rapid, reproducible, and can meet the requirements of process analysis.
