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.
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.
