Dimethylacetamide (N, N-Dimethylacetamide, DMAC) is a colorless transparent liquid, with water, alcohol, ether and other polar solvent mixture, with high thermal stability, low corrosion, low toxicity , Widely used in polyurethane, acrylic, pharmaceutical, pesticide and dyes and other industries. In recent years, DMAC gradually replaced the toxicity of dimethylformamide (DMF), the application requirements greatly increased.
Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., advancing with the times to scientific development as a guide, under the leadership of Wang Xiaoying manager, relying on Xiangying Institute of Analytical Technology, Institute of Chromatography, analysis and testing center, three scientific research units , The development of industrial N, N-dimethyl acetamide for the determination of special gas chromatograph, the establishment of industrial N, N-dimethyl acetamide (DMAC) and its impurity products, gas chromatography. Separated by a dedicated capillary column, hydrogen flame ionization detector (FID) on the detection, external standard method. Conclusion: The method is simple, rapid, accurate and sensitive. It is suitable for the simultaneous determination of industrial DMAC, NMA and impurity C.
