Embodiment

[0011] The phenol-free basic violet synthetic technique of the present embodiment comprises the following steps:

[0012] (1) N, N-dimethylaniline compounds are mixed with water to form a solution;

[0013] (2) Use copper salt as a catalyst, emulsify with a compound nonionic emulsifier, and oxidize the system at 80°C;

[0014] (3) Treat the oxidized material with a solvent method to obtain high-purity phenol-free basic violet with low copper content.

[0015] The phenol-free basic violet synthesis process does not require cumbersome post-reaction treatment, the process is simple and feasible, and it is environmentally friendly and pollution-free, and the reaction conditions are mild, realizing the industrial production of the product.
