Manufacturer Good Price Aniline CAS:62-53-3
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.

Manufacturer Good Price Methylene Chloride CAS:75-09-2
Methylene Chloride is a compound generated by two hydrogen atoms in methane molecules, and molecular CH2CL2.Methylene Chloride is colorless, transparent, heavier, and volatile liquid. It has a smell and sweetness similar to ether. It does not burn. Methylene Chloride is slightly soluble in water, and it dissolves with most commonly used organic solvents. It can also be dissolved in any proportion with other chlorine-containing solvents, ether, ethanol, and N-di metamimamamide. Methylene Chloride is difficult to dissolve in liquid ammonia at room temperature, which can be quickly dissolved in phenol, aldehyde, ketone, triathrin, tororine, cycamine, acetylcetate. The phase Chemicalbook is 1.3266 (20/4 ° C). The melting point -95.1 ° C. Boiling point 40 ° C. Fully low -boiling point solvents are often used to replace flammable petroleum ether, ether, etc., and can be used as local anesthesia, refrigerant and fire extinguishing agent. The spontaneous combustion point is 640 ° C. Decoction (20 ° C) 0.43MPa · s. The refractive index nd (20 ° C) 1.4244. Critical temperature is 237 ° C, and critical pressure is 6.0795MPa. HCL and traces of light are generated after thermal solution, and the water is heated for a long time to generate formaldehyde and HCL. Further chloride, CHCL3 and CCL4 can be obtained.
