Application: Determination of trace moisture in N-methyldiethanolamine





N-methylethanolamine compounds are an important class of fine chemical products, which are widely used in the fields of chemical industry, environmental protection, food and medicine. Such products include N-methylmonoethanolamine (MMEA, N-methyldiethanolamine (MDEA) and N,N-dimethylmonoethanolamine (DMEA), which are currently mainly synthesized by two methods: the first One is the ethylene oxide method, and the second is the N-alkylation method of ethanolamine.

The mass percentage of moisture in N-methyldiethanolamine is less than or equal to 0.4, which needs to be strictly controlled. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. developed a gas chromatography method for the determination of moisture in N-methyldiethanolamine, and the results were satisfactory.
