甲胺属重要的有机中间体。它是农药、医药、国防化工、橡胶、制革、合成染料、化学纤维、表面活化剂、照相等工业的极其重要的原料。国内外甲胺的主要生产方法采用的均是甲醇胺化气相催化法。由于其原料易得、工艺路线短、操作控制简便,设备及自控仪表均国产化、投资省、上马快、效益好等独特优点,对拥有甲醇产品的中、小型化肥厂颇有吸引力。
浩瀚色谱（山东）应用技术开发有限公司研究了采用气相色谱毛细管柱快速分离测定环境空气中一甲胺,二甲胺,三甲胺的含量的方法.结果表明,采用FID检测器,外标法直接进样,一甲胺,二甲胺,三甲胺的标准曲线线性良好,相关系数分别达0.998 3,0.997 5,0.996 6;空气中一甲胺,二甲胺,三甲胺*低检出质量浓度分别为17,29,24 ng/L,可满足环境空气中有机胺测定的要求.

Methylamine is an important organic intermediate. It is an extremely important raw material for pesticides, medicines, national defense chemicals, rubber, leather, synthetic dyes, chemical fibers, surfactants, photography and other industries. The main production methods of methylamine both at home and abroad are methanol amination gas-phase catalytic method. Due to its unique advantages such as easy availability of raw materials, short process route, simple operation and control, localization of equipment and automatic control instruments, low investment, fast start-up, and good benefits, it is quite attractive to medium and small fertilizer plants with methanol products.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has studied a method for the rapid separation and determination of monomethylamine, dimethylamine and trimethylamine in ambient air by gas chromatography capillary column. The results show that the use of FID detector and external standard method can directly Injection, the standard curves of monomethylamine, dimethylamine and trimethylamine have good linearity, and the correlation coefficients are 0.998 3, 0.997 5, 0.996 6, respectively; the minimum detected mass concentrations of monomethylamine, dimethylamine and trimethylamine in the air are It is 17, 29, and 24 ng/L, which can meet the requirements for the determination of organic amines in ambient air.
