    • PROBLEM TO BE SOLVED: To provide a method of producing a dispersion of a quinoline derivative in which the quinoline derivative is dispersed small-sized in high concentration. SOLUTION: The method of producing the dispersion of the quinoline derivative has a step for dissolving an N-aryl anthranilic acid derivative in an organic sulfonic acid to prepare a solution, a step for obtaining a reaction solution in which the quinoline derivative is formed by heating the solution to cause condensation ring closure reaction and a step for mixing the reaction solution and an aqueous solution in the presence of a dispersant to obtain the dispersion of the quinoline derivative. The step for mixing the reaction solution and the aqueous solution in the presence of the dispersant is carried out in a mixing field having a micro-flow path. COPYRIGHT: (C)2009,JPO&INPIT
