    二甲基乙酞胺(DMA叼是一种工业中广泛应用的极性有机溶剂。在芳香族聚酞亚胺秘聚跳胺合成及纺丝中也用它为溶剂。DMA。中含水对缩聚反应有严重影响,即使是少量的水,也会促使链终止,降低聚合链的分子量,因此对DMAc中含水需要严格控制。 

   滕州市浩瀚色谱仪器技术服务有限公司，研发出二甲基乙酰胺中微量水测定专用填充柱，气相色谱法分析ＤＭＡＣ中微量水的新方法，和常用的传统方法相比，该方法简单、快速、准确，其相对标准偏差在５％以下，回收率为９６一１０１％，获得满意结果。

Dimethylacetamide in the determination of trace water for special column
Vast chromatography: Business: chromatography equipment technology development, technology promotion and technical advice; sales: laboratory equipment.
       Extensive chromatography, providing a complete analysis program
       The vast majority of chromatography, analytical technology leader
       The vast number of chromatography, sales of not only products, more importantly, to help customers solve the problem, set up a bridge of spiritual communication

    Dimethyl acetamide (DMA Diao is a widely used in the industry of polar organic solvents in the aromatic polyimide sulfide synthesis and spinning is also used as a solvent. DMA. In the water on the polycondensation The reaction has a serious effect, even if a small amount of water, will also lead to the termination of the chain, reducing the molecular weight of the polymer chain, so the water in the DMAc need to be strictly controlled.

   Tengzhou vast chromatographic equipment technical services Co., Ltd., developed a dimethyl acetamide in the determination of trace water dedicated column, gas chromatography analysis of trace water in DMAC new method, compared with the traditional method, the method is simple and fast , The relative standard deviation of less than 5%, the recovery rate of 96 to 101%, to obtain satisfactory results.
