Abstract
PURPOSE: To obtain the title stable water-dispersible composition usable for pulp yield improvers to be added in the process of manufacturing pulp from lignocellulose, by kneading or pulverizing a water-insoluble quinone compound pwoder with an ionic surfactant.
CONSTITUTION: One part by wt. of water-insoluble quinone compound powder (Q), e.g. anthraguinone or 1, 4-dihydroanthraquinone, having a particle size≤100μ is homogeneously kneaded with 0.001W1 part by wt. of an ionic surfactant (S), e.g. semihardened beeftallow sodium, and, if necessary, a small amount, e.g. 0W5 parts by wt. of water to give a stable water-dispersible quinone composition. Alternatively, the powder (Q) is wet pulverized in the surfactant (S) solution.
