  • Dispersant for coal into oils
    Patent number: 4177039
    Abstract: A dispersant for coal into oils which comprises a metal salt of a dialkyl sulfosuccinate and a lower aliphatic alcohol and a coal-oil mixed fuel containing the dispersant. The coal-oil mixed fuel containing the dispersant is provided with excellent stability and fluidity for a long period of time by virtue of a high dispersing effect of the dispersant.

  • Dry process for the production of plastic-coated inorganic substances
    Patent number: 3967006
    Abstract: Dry process for the production of inorganic granular substances coated with plastics, characterized in that a radical-polymerizable vinylic monomer carried on the surface of an inorganic granular substance is brought in a gaseous phase into contact with gaseous sulfur dioxide to effect polymerization of the monomer. The resulting plastic-coated inorganic substances are useful in various fields of industry, for example, as fillers, construction materials, molding materials, electrode materials, delayed-action fertilizers, etc.
