Cyclohexylamine is a colorless organic liquid having a substituent of an amine group. Cyclohexylamine is used in low-pressure boilers where the condensate works for a longer period of time. It can remain along with condensate steam at various steam pressures which cannot be done with other neutralizing amines. It is a metabolite of cyclamate and has been found to be useful in production of other organic compounds.
Cyclohexylamine is produced by the catalytic hydrogenation of aniline. In contact with a ruthenium catalyst and in the presence of from about one to about 8 parts by weight of ammonia, aniline is hydrogenated under an absolute pressure of from about 2 to about 5 MPa at a temperature of from about 160° to about 180° C.
Cyclohexylamine is used especially for the industrial water treatment, for the production of cure accelerator, for the manufacturing of synthetic sweeteners and in a rubber industry for the production of vulcanization accelerators.
The accelerators of the present invention are the products obtainable by reacting a cyclohexylamine with an aldehyde and further reacting the product so obtained with carbon bisulfide and act as rubber accelerator.
