二甲胺是一種常用的有機化工產(chǎn)品，常溫下是一種無色氣體，在低濃度時有魚貝類氣味，在高濃度時有氨氣味，主要用作橡膠硫化促進劑、皮革去毛劑、醫(yī)藥、農(nóng)藥、紡織工業(yè)溶劑、燃料、晶圓沉積薄膜氣體、推進劑以及二甲肼、n，n-二甲基甲酰胺等有機中間體的原料。
目前二甲胺的提純方法一般是以甲醇和氨作為生產(chǎn)原料，應(yīng)用氣相法合成得到，由于傳統(tǒng)二甲胺制造工藝的特點，二甲胺產(chǎn)品中會還含有一定量的氨氣、水分、甲胺等雜質(zhì)，導(dǎo)致目前市售的二甲胺產(chǎn)品純度較低。特別作為生物試劑的原料時，二甲胺中含有的雜質(zhì)會直接影響試劑的檢測結(jié)果，因此亟需開發(fā)一種可以提高二甲胺產(chǎn)品純度的系統(tǒng)和方法。

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司采用HH-Tamine60甲胺專用毛細管柱測定二甲胺的純度及雜質(zhì)，柱效高，分離好，結(jié)果滿意。

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.
