Wha Is Ethylen Amine? Chemical Property, Application, Demand Status

January 21,2021

Ethylamine, also known as monoethylamine, is an important organic chemical raw material, and diethylamine, triethylamine are used in rocket fuel to medicines, dyes, solvents, fragrances, lubricants, surfactants(China span tween surfactants), rubber additives and ion exchange Resins have been widely used.

Molecular picture of ethylamine

Ethylamine is a compound with a molecular formula of C2H7N and a molecular weight of 45.08. It is a colorless and highly volatile liquid with the smell of ammonia and is alkaline. This product is highly toxic. It is highly irritating and can irritate the eyes, trachea, lungs, skin and excretory system.

Chemical Property

The aqueous solution is alkaline and its chemical properties are similar to methylamine.

①Salts with a certain melting point when interacting with inorganic acids, organic acids, acidic aromatic nitro compounds, etc. It forms complex salts with heavy metals such as copper and silver.

②Acidation reaction with acid chloride, acid anhydride, etc., to generate N-substituted amide. The salt formed with carboxylic acid is dehydrated to produce N-substituted amide. React with benzenesulfonyl chloride to generate N-substituted benzenesulfonamide. When reacting with hydroxylating reagents such as halogenated hydrocarbons, alcohols, phenols or ammonium salts, the hydrogen atoms on the nitrogen can be replaced by hydroxyl groups. Pass Cl2 into the ethylamine aqueous solution to generate N,N-dichloroethylamine.

③Addition reaction with cyanic acid, carbon disulfide, nitrile, epoxide, etc. Primary amine reacts with aliphatic or aromatic, dehydration to generate schiff base.

④ React with Grignard reagent to generate hydrocarbon.

It is unstable to light and decomposes to produce hydrogen, chlorine, ammonia, methane and ethane when irradiated with ultraviolet rays at 140~200℃. Pyrolysis is carried out at 490~555℃ under low pressure to generate hydrogen, chlorine, methane, etc.

Main Application

Used in the production of pesticide triazine herbicides, including atrazine and simazine. Both of these two herbicides use cyanuric chloride as raw materials, and their production processes are similar. Ethylamine is also used in the production of dyes, rubber accelerators, surfactants, antioxidants, ion exchange resins, aircraft fuels, solvents, detergents, lubricants, metallurgical mineral processing agents, and cosmetics and pharmaceuticals.

Demand for ethylamine

According to the analysis of the development status of the ethylamine industry in China, China ethylene amine demand was 37,200 tons in 2016, 40,300 tons in 2017, and 44,400 tons in 2018. The demand for ethylamine is 48,500 tons, and China's demand for monoethylamine is 25,300 tons in the first half of 2020. Generally, the demand for ethylamine is increasing year by year .
