Production method of quinacridone pigment or mixed crystal pigment thereof

The invention belongs to the field of pigments, and relates to a production method of a quinacridone pigment or a mixed crystal pigment thereof, namely an environment-friendly and economical production method of the quinacridone pigment. The method comprises the following steps: cyclizing diphenylamino terephthalic acid or a derivative thereof in a formula (2); hydrolyzing the reaction mixture obtained by cyclization with water at 0-100 DEG C; separating out a crude pigment obtained in this way, then pulping the crude pigment in an aqueous medium without any additive, completing crystal form transformation of the pigment and curing of pigment particles at 120-170 DEG C in a closed reaction kettle, then directly separating or adding a surface modifier for surface modification, and then separating to obtain the pigment. Crystal form transformation and pigment particle curing are completely completed in an aqueous medium, and the method is environmentally friendly and low in cost.

METHOD FOR MANUFACTURING DISPERSION OF QUINOLINE DERIVATIVE

A method for manufacturing a dispersion of a quinoline derivative that is dispersed at a high concentration and has a small particle size. The method includes the steps of preparing a solution by dissolving an N-arylanthranilic acid derivative in an organosulfonic acid, heating the solution and obtaining a reaction liquid in which a quinoline derivative has been produced by a condensation ring-closing reaction, and obtaining a dispersion of the quinoline derivative by mixing the reaction liquid with an aqueous solution. The step of mixing the reaction liquid with an aqueous solution may be performed in a mixing field having a micro-channel.
