PURPOSE:To obtain a monomethylene imine compound and bismethylene imine compound at the same time, by reacting a mixture of primary aliphatic monoamine and primary aliphatic diamine with formaldehyde and thermally decomposing the reaction product. CONSTITUTION:An amine mixture obtained by mixing a primary aliphatic monoamine expressed by the formula R1-NH2 (R1 is alkyl or aralkyl) with a primary aliphatic diamine expressed by the formula NH2-R2-NH2 (R2 is alkylene or aralkyl) in a molar ratio of 1.2-8:1 is reacted with formaldehyde in an inert hydrocarbon solvent at <=50 deg.C. Then an alkali is added to the reaction product to provide a mixture of poly tert. amine compounds having hexahydro-sym-trazine structure, which is then thermally decomposed at 110-220 deg.C to afford the aimed product useful as a raw material of instantaneous adhesive and chemicals, catalyst for various kinds of urethane foams, curing agent for epoxy resin, coating stabilizer, etc.
