ETHYLAMINE ANHYDROUS, PRESSURE TIN WITH 100 ML - Preparation Method
Open Data Verified Data
- ethanol (gas phase) amination method ethanol and ammonia are fed in a ratio of 4:1 at a temperature of 350 to 400 ° C. And 2. Under the pressure of 45~2.94MPA, with Al2 03 as Catalyst, the ammoniation reaction was carried out to obtain crude ethylamine. The finished product was obtained by fractional distillation.
- acetaldehyde and hydroamination method ethylamine can be obtained by reacting acetaldehyde, hydrogen and ammonia as raw materials and nickel as a catalyst. First of all, the structure catalyst with nickel as the main catalyst, the reduction of copper, the reduction of chromium as the promoter and the kaolin as the carrier is loaded into the reactor, and the space velocity is 0. 03~0.15L.h-I is introduced into acetaldehyde and the ratio of hydrogen to acetaldehyde is 5:1, and the ratio of ammonia to acetaldehyde is (0.4-3):1. The feedstock was gasified and entered the reactor at 80 °c. The reaction temperature was controlled between 105 and 200 °c. The product was cooled at -5 °c and isolated as A, Di, and triethylamine. Since the formation rate of monoethylamine is faster than that of di-and triethylamine, it is easier to obtain a large amount of ethylamine. When the main product is required to be di-and triethylamine, the formed monoethylamine needs to be recycled to the reaction system for reaction.

| Product characteristics | ethylamine, also known as aminoethane, ethylamine, is a colorless transparent liquid, highly volatile, ammonia flavor, flammable, relative molecular mass 45.09. The relative density was 0.6829. Melting Point -80.6 °c. Boiling point 16.6 °c. Flash, dot-17C (closed). Spontaneous combustion at 555 °c in air. Refractive index 1.3663. Miscible with water, ethanol and ether. Strongly alkaline. Reaction with an inorganic acid produces a water-soluble salt. Reaction with an acyl group produces an amide. The reaction with nitrous acid produces nitrosamines. Can be oxidized to form hydroxylamine or oxime. When burning in air, the flame is light blue. Reaction with phosgene to produce phosgene. Reaction with acrylonitrile to produce aminopropionitrile. Strong irritation of the skin and mucous membranes. Rat oral LD50400mg/kg. Storage should use stainless steel containers and stainless steel valves. ethylamine can be prepared by reacting ethyl iodide (ethyl chloride) with ammonia in liquid ammonia (ethanol solution). Or acetonitrile as raw material, using nickel as catalyst, high pressure hydrogenation reduction can also be prepared. It is mainly used as the raw material of pesticide triazine herbicides to produce herbicides atrazine (selective herbicide) and Simazine (pre-emergence herbicide). Dyes, surfactants, detergents, lubricants, ion exchange resins and other raw materials; Resin and rubber slurry stabilizers; Antioxidants; Oil refining additives; Metallurgical ore dressing agent; Pharmaceutical raw materials; Solvents and extractants; the oxalate salt of ethylamine can be used for medicinal purposes. |
| Use | for the production of dyes, pharmaceuticals, surfactants, herbicides, rubber vulcanization accelerator and ion exchange resin, etc. ethylamine is a fungicide, such as downy urea-Cyanogen, dipyridinol, insecticide amidodicarb, herbicide atrazine, simazine, grass Dan, the intermediates of diphenoxylamine and others. used in the production of pesticides triazine herbicides, including atrazine and Simazine ([122-34-9]). These two herbicides are cyanuric chloride as raw material, the production process is also similar. Atrazine (also known as telatrazine) has a wider application range than simazine, and can kill the weeds resistant to Simazine. It was developed and produced by the Swiss company in 1985, and later developed into the largest herbicide in the world. Ethylamine is also used in the production of dyes, rubber accelerators, surfactants, antioxidants, ion exchange resins, aircraft fuels, solvents, detergents, lubricants, metallurgical ore dressing agents, and cosmetics and pharmaceuticals. used in organic synthesis, also used as dye intermediate, stabilizer and emulsifier used in the synthesis of organic resins and dyes |
| production method | 1. Ethanol (gas phase) ammoniation method ethanol and ammonia are fed in a ratio of 4:1 at a reaction temperature of 350-400 ° C. And a pressure of 2.45-2.94MPa, and alumina is used as a dehydration catalyst. In addition to the formation of ethylamine, side reactions produce diethylamine, triethylamine, as well as diethyl ether, acetonitrile and ethylene. The crude product obtained by condensing the reaction gas is distilled off ammonia, and then ethylamine is distilled off, and the content is more than 95%. In general, a 50% aqueous solution is used as a commercial product, and about 50% of ethanol (95%) is consumed per ton of the aqueous solution. Acetaldehyde, ammoniation of hydrogen and ammonia acetaldehyde as raw materials, nickel as a catalyst for the reaction can be ethylamine. First, the structure catalyst with nickel as the main catalyst, copper reduction, chromium reduction as the promoter and kaolin as the carrier is loaded into the reactor, acetaldehyde is introduced at a space velocity of 0.03-0.15L · h-1 so that the ratio of hydrogen to acetaldehyde is 5:1 and the ratio of ammonia to acetaldehyde is 0.4-3:1. The feedstock was gasified and entered the reactor at 80 °c. The reaction temperature was controlled between 105 and 200 °c. The product was cooled at -5 °c and isolated as A, Di, and triethylamine. Since the formation rate of monoethylamine is faster than that of di-and triethylamine, it is easier to obtain a large amount of ethylamine. When the main product is required to be di-and triethylamine, the formed monoethylamine needs to be recycled to the reaction system for reaction. The preparation method is ethanol gas phase amination method, the mixture of ethanol and ammonia in the reaction temperature of 390~400 ℃, 2.53~3.04 MPa pressure through the catalyst to obtain crude ethylamine, the final product is obtained by fractionation.
