Abstract: This invention relates to stable, fluid zinc-containing dispersions and the preparations thereof by the high temperature decomposition of zinc acetate to ZnO in a dispersant-containing fluid, said dispersant being stable at the temperature of decomposition.

Abstract: This invention relates to a process of preparing stable suspensions of Mg(OH).sub.2 which comprises blending Mg(OH).sub.2 powder with acid in a surfactant-containing fluid to effect particle size reduction of the starting Mg(OH).sub.2 powder. In practice, the mole-fraction of acid employed is less than 50% of that stoichiometrically necessary for the formation of the magnesium salt.

Abstract: This invention relates to a stable, fluid magnesium oxide-containing dispersion prepared by the thermal treatment of MgO powder in a non-volatile fluid in the presence of a stoichiometric or lesser amount of a carboxylic acid as illustrated by acetic acid.

Abstract: This invention relates to a process of treating hydrated chromium oxides with aqueous base(s) in the presence of dispersing agent(s) to form upon dehydration a virtually sediment-free oil solution and/or dispersion of hydrated chromium oxide in amounts up to about 20% chromium content. The product formed is a stable, bright, fluid oil-soluble and/or oil-dispersible hydrated chromium oxide upon filtration or centrifugation to remove minimal sediment.

Abstract: This invention relates to stable, fluid magnesium-containing dispersions and the preparations thereof by the high temperature dehydration of Mg(OH).sub.2 to MgO in a dispersant-containing fluid.

Abstract: This invention relates to stable, fluid magnesium-containing dispersions and the preparations thereof by the high temperature decomposition of MgCO.sub.3 to MgO in a dispersant-containing fluid.

Abstract: This invention relates to stable, fluid zinc-containing dispersions and the preparations thereof by the high temperature decomposition of ZnCO.sub.3 to ZnO in a dispersant-containing fluid.

Abstract: This invention relates to stable, fluid magnesium-containing dispersions and the preparations thereof by the high temperature decomposition of Magnesium salts of carboxylic acids to MgO in a dispersant-containing fluid.

Abstract: This invention relates to stable, fluid CaCO.sub.3 -containing dispersions, and the preparations thereof by the high temperature decomposition of a Ca carboxylate such as Ca acetate, etc., in a dispersant-containing fluid.

Abstract: This invention relates to copolymers of alpha-olefins and maleic anhydride reacted with amines in the presence of Lewis acids, preferably BF.sub.3 or a complex thereof; and to the use of these products as anti-static agents in organic liquids, preferably in hydrocarbons. The use of Lewis acid produces a unique reaction product which is superior as to fluidity and/or anti-static properties as compared to the corresponding product produced without Lewis acid. In addition, the use of Lewis acid promotes the rate of reaction thus reducing reaction time.

Abstract: This invention relates to stable, fluid magnesium-containing dispersions and the preparations thereof by the high temperature decomposition of Magnesium salts of carboxylic acids to MgO in a dispersant-containing fluid, where less than a stoichiometric amount of carboxylic acid is employed in forming the magnesium carboxylates, based on Mg(OH).sub.2 or equivalent.
