Manufacturer Good Price Aniline CAS:62-53-3

short description:

Aniline is the simplest aromatic amine, benzene molecule in a hydrogen atom for the amino group of compounds generated, colorless oil flammable liquid, strong smell. The melting point is -6.3℃, the boiling point is 184℃, the relative density is 1.0217(20/4℃), the refractive index is 1.5863, the flash point (open cup) is 70℃, the spontaneous combustion point is 770℃, the decomposition is heated to 370℃, slightly soluble in water, easily soluble in ethanol, ether, chloroform and other organic solvents. Turns brown Chemicalbook color when exposed to air or sunlight. Available steam distillation, distillation to add a small amount of zinc powder to prevent oxidation. 10 ~ 15ppm NaBH4 can be added to the purified aniline to prevent oxidation deterioration. Aniline solution is basic, and acid is easy to form salt. The hydrogen atom on its amino group can be replaced by a hydrocarbon or acyl group to form secondary or tertiary anilines and acyl anilines. When the substitution reaction is carried out, the adjacent and para-substituted products are mainly formed. Reaction with nitrite yields diazo salts from which a series of benzene derivatives and azo compounds can be made.

Description

Aniline is an important chemical raw material, the production of more important products up to 300 kinds, mainly used in MDI, dye industry, medicine, rubber vulcanization promoters, such as p-aminobenzene sulfonic acid in dye industry, medicine industry, N-acetanilide, etc. It's also used to make resins and paints. In 2008, the consumption of aniline was about 360,000 tons, and the demand is expected to be about 870,000 tons in 2012. Chemicalbook has a production capacity of 1.37 million tons, with an excess capacity of nearly 500,000 tons. Aniline is very toxic to the blood and nerves, and can be absorbed through the skin or cause poisoning through the respiratory tract. There are two main methods to produce aniline in industry: 1. Aniline is prepared by hydrogenation of nitrobenzene catalyzed by active copper. This method can be used for continuous production without pollution. 2, chlorobenzene reacts with ammonia at high temperature in the presence of copper oxide catalyst.

Applications of Aniline

1. Aniline is one of the most important intermediates in the dye industry, and it is also the main raw material for medicine, rubber promoters and anti-aging agents. It can also be used to make spices, varnishes and explosives, etc. Aniline is used in the manufacture of dyes, medicines, resins, varnishes, perfumes, Chemicalbook vulcanized rubber and even solvents. Hazardous and harmful substances affecting the early life stages of Marine animals. According to the US Environmental Protection Agency (EPA), Environmental and food contaminants, Drinking water contaminants Candidate Compound 3(CCL3).
2. Aniline is an important raw material, the production of pesticides can be derived from aniline, alkyl aniline, N - alkyl aniline adjacent nitro aniline, o-phenylendiamine, phenylhydrazine, cyclohexylamine etc., can be used as a fungicide against rust sodium, the seed spirit, amine methyl Chemicalbook sterilization, sterilization amine, carbendazim, its spirit, benomyl, triazophos insecticide, pyridazine sulfur phosphorus, quetiapine phosphorus, Intermediates of herbicides alachlor, acetochlor, butachlor, cycloazinone, imidazole quinolinic acid, etc.
3. Aniline is an important intermediate. More than 300 kinds of important products are produced from aniline. There are about 80 aniline manufacturers in the world, the total annual production capacity has exceeded 2.7 million t/a, the output of about 2.3 million t; The main consumption area is MDI, which accounts for 84% of the total consumption of aniline in 2000. In our country, aniline is mainly consumed in the MDI, dye industry, rubber additive, medicine, pesticide and organic intermediates. The consumption of aniline in 2000 is 185,000 t, and the shortage of production needs to be solved by import.
