Properties, application and production process of cyclohexylamine
The physical and chemical properties
Cyclohexylamine also known as amino cyclohexane, hexahydroaniline. Colorless transparent liquid. Intense smell of fish and ammonia. Flammable.
The molecular weight is 99.18.
The relative density was 0.8191.
Melting point - 17.7 ℃.
Boiling point 134.5 ℃, 118.9 ℃ (6.67 x 104 pa), 102.5 ℃ (4.00 x 104 pa), 72.0 ℃ (1.33 x 104 pa), 56.0 ℃ (6.67 x 103 pa), 45.1 ℃ (4.00 x 103 pa), 41.3 ℃ (3.33 x 103 pa), 36.4 ℃ (2.67 x 103 pa), 30.5 ℃ (1.99 x 103 pa), 25.0 ℃ (1.17 x 103 pa).
The refractive index is 1.4372.
Flash point 32 ℃.
Ignition point 265 ℃.
Soluble in water, can be miscible with ethanol, ether, acetone, ethyl acetate, chloroform, heptane, benzene and other general organic solvents. Cyclohexylamine can evaporate with water vapor. Carbonates that absorb carbon dioxide from the air and form white crystals. It forms an azeotropic substance with water at an azeotropic point of 96.4℃ and contains 55.8% water. The aqueous solution is basic. PH of 0.01% aqueous solution =10.5. The vapor forms an explosive mixture with the air. This product is poisonous, irritates skin and mucous membrane, and causes gangrene. When inhaled, it has an anesthetic effect but does not cause blood poisoning. The rats were LD50710mg/kg orally.
The maximum permissible concentration in the workplace is 10×10-6. Methylcyclohexane was co-heated with hydrogen iodide in a sealed tube at 200℃. Methylcyclohexamine and a small amount of dimethylcyclohexamine were co-heated with dimethyl sulfate in ethyl ether. The hydrochloride reacted with sodium nitrite to obtain cyclohexanol, and reacted with excessive ammonia and zinc chloride to obtain 2-methylpyridine.
Details
Preparation method:
Cyclohexylamine can be prepared by catalytic reduction of aniline under high temperature and high pressure (nickel or cobalt). It can also be prepared from cyclohexanol and cyclohexanone obtained by catalytic reduction of phenol as raw materials, and then amination with ammonia. Industrial cyclohexylamine is mainly used as a thiazole vulcanization accelerator for rubber, and can also be used as a tank agent, dyeing AIDS and surfactants. The above information was compiled by Nan Xiao of Chemicalbook.
The main purpose
Cyclohexylamine can be used as raw material of surfactant to produce cyclohexylamine alkylbenzene sulfonate, used as emulsifier and foaming agent; Flavor raw materials, the production of allyl cyclohexyl propionate; Dye raw material, the production of acid blue 62, disperse fluorescent yellow, disperse fluorescent yellow H5GL, weak acid blue BRN, disperse blue 6 and dye additives; A food additive for sweetening ingredients; Cyclohexylamine can be used in the production of cyclohexylamine sulfonate and sodium cyclohexylamine sulfonate, the latter is a sweetener 30 times sweeter than sucrose, the trade name of cyclamate, approved by the Ministry of Health of China for pickles, sauces, confection wine, cakes, biscuits, bread, frozen drinks, drink Chemicalbook material, the maximum usage of 0.65g/kg. Pesticide raw materials, the production of fruit tree insecticide "Carmite", herbicide Wilber and fungicide; Used for the preparation of petroleum product additives, boiler feed water treatment agent and corrosion inhibitor; Rubber vulcanization accelerator raw materials, the production of thiazole vulcanization accelerator CZ, this vulcanization accelerator vulcanization work performance is good, especially suitable for SBR, FDA rubber; Used as antirust agent, production of antirust paper; Tank; Antifreeze; Antistatic agents (textile additives), latex coagulants and petroleum product additives; Because of the alkalinity of cyclohexylamine aqueous solution, it can be used as absorbent to remove carbon dioxide and sulfur dioxide.
