Dicyclohexylamine Treating Process

The invention relates to a refining method of dicyclohexylamine, belonging to the technical field of organic chemistry. Soluble in solvents, materials will be under the action of reducing agent and proton acid, imine reduction for dicyclohexylamine.

The reaction temperature is 20 ℃ - 35 ℃, pH control in 5 above, reaction pressure to atmospheric pressure, reaction time was 0.25 h - 1.5 h, after the reaction of vacuum distillation, after purification products, products which based on the content of dicycloheximide as an index, the product in the second The residual amount of hexylamine was 0-0.4%.
