Abstract: An efficient, eco-friendly ionic liquid was described for the synthesis of symmetric triarylmethane derivatives via Baeyer condensation of N,N-dimethylaniline with different active aromatic aldehyde compounds using amide ionic liquid as a catalyst. The syntheses were achieved for the first time using amide ionic liquid as a catalyst eliminating the need for a volatile organic solvent. The advantages of this ionic liquid are low cost and operational simplicity.

The invention discloses a double-4' - N, N - dimethyl aniline - 1 - naphthyl methane compound of the preparation method, is the 1 - naphthalene formaldehyde and N, N - dimethyl aniline is added to the reaction vessel, after shaking, in the reaction vessel to add catalyst N, N - dimethyl formamide sulfuric acid hydrogen radical ion liquid, heating, thermal insulation 3 - 6 h, after the reaction, the reaction bottle adding water and organic solvent, shake thoroughly after the step of separating the oil, oil add saturated NaCl solution, separating the oil standing shaking, the oil reservoir for anhydrous MgSO4 Drying, the resulting clear liquid and steaming and removing ethyl acetate, column chromatography separation to obtain the used for the dye industry leather dyeing or coloring of the paper double 4' - N, N - dimethyl aniline - 1 - naphthyl methane compound. In the present invention the catalyst is easy to prepare, pollution is small, the reaction does not use solvent in, the preparation process is simple in operation, simple treatment after the reaction, environmental protection, the yield of the product is high.
