N-methyldiethanolamine for industrial use -- Determination of water content -- Packed column

Details of packed column for determination of water in N-methyldiethanolamine for industrial use:


This document specifies the technical requirements, test methods, inspection rules, marks, packaging, transportation and storage of N-methyldiethanolamine for industrial use.

This document is applicable to industrial N-methyldiethanolamine synthesized from ethylene oxide and monomethylamine. It is mainly used for desulfurization of oil and natural gas and decarburization of other industrial gases, as well as for pharmaceutical intermediates and raw materials of some fine chemical products.

Molecular formula: CH3N (CH2CH2OH) 2


The mass fraction of water in N-methyldiethanolamine is ≤ 0.4%. In the national standard, GB-T 6283 Karl Fischer method is used. The operation is complex, the analysis time is long, and the efficiency is low, which cannot meet the needs of supply, production and detection. Vast chromatography keeps pace with the times. The gas chromatography method developed for the determination of water in industrial N-methyldiethanolamine has high column efficiency, good separation, and satisfactory results.
