二甲胺是一种常用的有机化工产品，常温下是一种无色气体，在低浓度时有鱼贝类气味，在高浓度时有氨气味，主要用作橡胶硫化促进剂、皮革去毛剂、医药、农药、纺织工业溶剂、燃料、晶圆沉积薄膜气体、推进剂以及二甲肼、n，n-二甲基甲酰胺等有机中间体的原料。
目前二甲胺的提纯方法一般是以甲醇和氨作为生产原料，应用气相法合成得到，由于传统二甲胺制造工艺的特点，二甲胺产品中会还含有一定量的氨气、水分、甲胺等杂质，导致目前市售的二甲胺产品纯度较低。特别作为生物试剂的原料时，二甲胺中含有的杂质会直接影响试剂的检测结果，因此亟需开发一种可以提高二甲胺产品纯度的系统和方法。

浩瀚色谱（山东）应用技术开发有限公司采用HH-Tamine60甲胺专用毛细管柱测定二甲胺的纯度及杂质，柱效高，分离好，结果满意。

Dimethylamine for industrial use Determination of purity Gas chromatography

Details of gas chromatography for determination of purity of industrial dimethylamine:



Name: HH-Tamine60 methylamine special capillary column



Specification: 60m * 0.32mm * 5.0um



Maximum operating temperature: 280 ° C



No.: 20221129001




Dimethylamine is a commonly used organic chemical product. It is a colorless gas at room temperature. It smells of fish and shellfish at low concentrations and ammonia at high concentrations. It is mainly used as a raw material for rubber vulcanization accelerator, leather hair remover, medicine, pesticide, textile industry solvent, fuel, wafer deposition film gas, propellant and organic intermediates such as dimethylhydrazine, n, n-dimethylformamide.

At present, the purification method of dimethylamine is generally based on methanol and ammonia as production raw materials, which are synthesized by gas phase method. Due to the characteristics of traditional dimethylamine manufacturing process, dimethylamine products will also contain a certain amount of ammonia, water, methylamine and other impurities, leading to the low purity of currently marketed dimethylamine products. Especially when it is used as the raw material of biological reagents, the impurities contained in dimethylamine will directly affect the detection results of reagents. Therefore, it is urgent to develop a system and method that can improve the purity of dimethylamine products.



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. used HH-Tamine60 methylamine special capillary column to determine the purity and impurities of dimethylamine, with high column efficiency, good separation and satisfactory results.
