　   DMF在常温、常压下为无色透明液体,其折光率n25D为1.4275～1.4290,能与水及一般极性有机溶剂混溶,在有机合成领域是一种应用广泛的优良溶剂。我们在一种产品的生产过程中需用到无水DMF,因此,在使用过程中准确快速测定其中的水分含量,对其回收起着重要作用。

   滕州市浩瀚色谱仪器技术服务有限公司，研发出HH-DMF-IIN,N-二甲基甲酰胺中水分的含量测定专用柱，测定N,N-二甲基甲酰胺(DMF)中水分含量的方法,该方法具有操作简单,准确度高,重复性好等优点,非常适用于化工生产行业中的现场监控。用该法测定高、中、低三个不同浓度添加量的相对误差(RE)在0.8%～2.0%之间,对同一样品重复测定的标准偏差(SD)为0.45,相对标准偏差(RSD)为2.85%(n=6)。

DMF at room temperature, atmospheric pressure is a colorless transparent liquid, the refractive index n25D 1.4275 ~ 1.4290, with water and the general polar organic solvent immiscibility, in the field of organic synthesis is a widely used excellent solvent. We use anhydrous DMF in the production of a product. Therefore, it is important to quickly and accurately measure the moisture content in the process of use, and it plays an important role in its recovery.
   Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., developed HH-DMF-IIN, N-dimethyl formamide in the determination of moisture content of the column, the determination of N, N-dimethyl formamide (DMF) in the water content Method, which has the advantages of simple operation, high accuracy and good reproducibility, and is very suitable for on-site monitoring in chemical production industry. The relative error (RE) of the three different concentrations of high, medium and low was 0.8% ~ 2.0%, the standard deviation (SD) was 0.45, the relative standard deviation (RSD) Was 2.85% (n = 6).
