Cyclohexylamine is also called aminocyclohexane and hexahydroaniline.
Its molecular formula is C 6 H 13 N, its molecular weight is 99.
18, and its structural formula is
1.
Product performance
Colorless liquid, freezing point -17.
7℃, boiling point 134.
5℃, 36.
4℃ (2.
7kPa), relative density 0.
8647 (25/25℃), refractive index 1.
4565 (25℃), flash point 32℃; compatible with water and general organic solvents (Alcohols, esters, ketones, ethers, aliphatic hydrocarbons, aromatic hydrocarbons and their chlorinated compounds) are miscible; form an azeotrope with water, with a boiling point of 96.
4°C; strongly alkaline, the pH of a 0.
01% aqueous solution is 10.
5, with strong The fishy smell
.
2.
Production principle
It is produced by hydrogenation of aniline under the action of a catalyst, and can be produced by the normal pressure method and the pressurized method
.

Production process
Atmospheric pressure method: first mix aniline vapor and hydrogen according to a mass ratio of 100:40.
7, and then send the mixed gas into the catalytic hydrogenation reaction gold
.
Under the catalysis of a cobalt catalyst, the atmospheric hydrogenation reaction is carried out at 150~180℃, and the space velocity is 0.
Pressurization method: firstly mix aniline and hydrogen in a mass ratio of 100:20.
4, and send them to the catalytic hydrogenation reactor with cobalt as the catalyst.
The reaction temperature is 240°C, the pressure is 14.
71-19.
61MPa, and the space velocity is 0.
4~ 0.
7m 3 /h, liquid phase hydrogenation via a fixed bed
.
After the hydrogenation reaction is completed, the material is cooled, and then fractionated to collect cyclohexylamine.

Product use
Mainly used as a denaturant for viscose fibers, which can improve the physical and mechanical properties of viscose fibers; it can also be used as an organic synthesis intermediate to produce cyclohexanol , cyclohexanone, caprolactam, etc.
; it can also be used as a dye intermediate; antiprotozoal agent, a vulcanization accelerator, a metal corrosion inhibitor additives and plastics
.

Safety measures
(1) The raw materials aniline and cyclohexylamine are both highly toxic, which can irritate the skin and mucous membranes and cause jaundice.
Inhalation of vapor can cause nausea and anesthesia
.
Flammable, the allowable amount in the air is 10mg/L
(2) Packed in 100kg iron drum and stored in a cool, ventilated and dry place
.
Prevent sunlight, isolate heat and fire
