PROBLEM TO BE SOLVED: To prepare an oxidation inhibitor dispersion which is excellent in storage stability, and in which, when an oxidation inhibitor is recovered as a solid, it is possible to suppress the discharge out of a system. SOLUTION: The oxidation inhibitor dispersion comprises the oxidation inhibitor, a dispersing agent, and water. The oxidation inhibitor has an average particle size of 1-5μm, and the oxidation inhibitor dispersion has a viscosity of 100-300 cP. When the dispersion is coagulated with an acid and then neutralized with an alkali, at least 80 wt% particles of which have a particle size of at least 150μm. COPYRIGHT: (C)2005,JPO&NCIPI
