ABSTRACT:
A method and composition for controlling an exothermic reaction between a powerful oxidizing agent such as the permanganate salts, and reducing agents such as polyhydroxy organic compounds, comprises non-charged, relatively hydrophobic pigments which can be slurried at relatively high solids. The pigment may be calcium carbonate, diatomaceous earth (diatomite), talc, or blends thereof. The pigments are not flocculated in permanganate slurries and can be dispersed at high solids contents. The dispersions can be spray dried or pelletized with controllable moisture contents from about 0.1 to 10%. The resulting composition yields effective control of the exothermic reaction with more uniform and reproducible results.
