Preparation method of 4,4'-methylene-bis-(3-chloro-2,6-diethylaniline)

The invention discloses a preparation method of 4,4'-methylene-bis-(3-chloro-2,6-diethylaniline). The preparation method comprises the following steps: (1) in a nitrogen protective atmosphere, carrying out reaction on raw materials 2,6-diethylaniline and hydrochloric acid to generate 2,6-diethylaniline hydrochloride, and dropwisely adding formalin to carry out condensation reaction; after the reaction finishes, neutralizing with liquid caustic soda, and carrying out water separation to obtain 4,4'-methylene-bis-(2,6-diethylaniline); (2) dissolving the product in the step (1) in a solvent, and introducing chlorine to carry out chlorination reaction; after the reaction finishes, neutralizing with liquid caustic soda, and carrying out water separation to obtain a 4,4'-methylene-bis-(3-chloro-2,6-diethylaniline) crude product; and (3) dissolving the product in the step (2) in a solvent, decolorizing with activated carbon, cooling to crystallize, filtering, and drying to obtain the final product. The method has the advantages of simple technique, accessible raw materials, low price and high product purity and yield, and can easily implement industrial production.
