Abstract
The invention relates to a process for preparing dicyclohexylamine nitrite by the reaction of cyclohexylamine with cyclohexanone, followed by the reaction of the resulting dicyclohexylamine with ammonium nitrite, consisting in that the reaction of cyclohexylamine with cyclohexanone takes place in the presence of the formic acid, either in a reaction medium consisting of acetic acid, formic acid or xylol, or in the absence of every reaction medium, the resulting dicyclohexylamine-containing solution being further treated with an aqueous solution of ammonium nitrite.
