In a method for the production of cyclohexanecarboguanamine by the reaction of cyanocylohexane with dicyandiamide in an organic solvent possessing a hydroxyl group in the molecular unit thereof at a temperature in the range of 90.degree. to 200.degree. C. in the presence of a basic catalyst, the improvement which comprises carrying out the reaction using 0.60 to 0.95 mol of dicyandiamide per mol of cyanocylohexane in an atmosphere substantially incapable of producing any effect of oxygent.

Method for production of cyclohexanecarboguanamine

A method for the production of methylolaminotriazine condensate by the reaction of cyclohexanecarboguanamine (A) and formaldehyde (B), which method comprises preparing a solution of formaldehyde (B) or a solution containing cyclohexanecarboguanamine (A) and formaldehyde (B) in such amounts that the molar ratio of (A)/(B) will be not more than 1/2.5, keeping the temperature of said solution in the range of 55.degree. to 150.degree. C. and, at the same time, gradually supplying cyclohexanecarboguanaimine (A) thereto.
