Organophilization of a Brazilian Mg-montmorillonite without prior sodium activation

The use of Mg-montmorillonite in the production of organoclay without sodium activation was investigated. For this purpose, organophilization experiments were carried out by varying the concentration of two surfactants: hexadecyltrimethylammonium (HDTMA+) and dodecyltrimethylammonium (DTMA+) ions. T...
