    二甲基乙酰胺(DMAc)是一种工业中广泛应用的极性有机溶剂。在芳香族聚酰亚胺和聚酰胺合成及纺丝中也用它为溶剂。DMAc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，与时俱进，以科学发展观为指导，在王晓莹经理的带领下，依托翔鹰分析技术研究所，色谱工程研究所，分析与测试ZX，3个科研单位，研发出二甲基乙酰胺分析专用毛细管柱，测定了DMAC纯度及杂质含量，结果满意。

    Dimethylacetamide (DMAc) is a widely used polar organic solvent in industry. It is also used as a solvent in the synthesis and spinning of aromatic polyimides and polyamides. The water content in DMAc has a serious effect on the polycondensation reaction. Even a small amount of water will cause the chain to terminate and reduce the molecular weight of the polymer chain. Therefore, the water in the DMAc needs to be strictly controlled.

   Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., advancing with the times to the scientific concept of development as a guide, under the leadership of Wang Xiaoying manager, relying on Xiangying Institute of Analytical Technology, chromatography and engineering research, analysis and testing center, Units, developed a dimethyl acetamide analysis dedicated capillary column, measured the purity of DMAC and impurity content, the results were satisfactory.
