ABSTRACT:
This invention is directed to a process for the production of organophilic clays and more particularly to a dry process for the production of organophilic clays useful for thickening various fluids including mineral oils, drilling fluids, paints, and lubricants such as mineral oils. The process comprises thoroughly mixing at least one organic ammonium salt with specific amounts of substantially water-free clays and vigorously blending the organic ammonium salt and the dry clay at temperatures at least above the melting point of the organic ammonium salt to drive-off any liquids resulting from the dry reaction.
