N- methyl diethanolamine Determination Application:
 
This method can be applied in N- methyl diethanolamine (MDEA) into the plant raw material quality control, quality production process intermediate track, and the reaction in the production process to analyze the causes of impurities monitor, thus reducing production consumption, improve product yield, quality, thereby enhancing economic efficiency. N- methyl diethanolamine (MDEA) as an important chemical products, widely used in medicine, paint, emulsifiers, paint driers, pesticides, fiber additives, coating catalyst in, oil gas and gas desulfurization Purification emulsifiers, pH control agents, polyurethane foam catalyst. Further, N- methyldiethanolamine may also be used as insecticides, emulsifier N- methyldiethanolamine, N- methyldiethanolamine fabric aids the semi anticancer drugs mechlorethamine hydrochloride intermediates, amino acid acrylate coating catalyst, is also industrial gas decarbonization agent, so in recent years in the flue gas is gradually promote the absorption of carbon dioxide.
 
About N- methyldiethanolamine
 
Currently, the determination of N- methyl diethanolamine (MDEA) content, have not yet developed national standards, methods described in the literature of a gas chromatograph and acid neutralization capacity law, basic impurities serious interference. Measured by gas chromatography amine derivative is generally subject to tedious, time-consuming. To this end, Wuhan Hanson GC2020 gas chromatograph N- methyl diethanolamine (MFEA), N- methyl ethanolamine and impurities by capillary gas chromatography have been studied, it may not require derivative process and shorten the analysis time. Chromatography with a high separation efficiency, speed and other characteristics analyzed using capillary gas chromatography can be simultaneously mixed MDEA amine solution and impurities are separated, as used herein, capillary column dedicated column, FID, the method is simple, rapid, so satisfactory.
