INVESTIGATION ON THE PROCESS OF SYNTHESIS ORGANOCLAYS FROM BENTONITE (THANH HÓA) AND TETRADECYLTRIMETHYL AMMONIUM BROMIDE

Abstract

    Organoclay synthesis from bentonite (Thanh Hoa) and tetradecyltrimethyl ammoniumbromide (TĐTM) in water solvent is studied by the methods as XRD, IR, TGA, SEM.In optimal conditions examined: reaction temperature of 500C, the volume ratio ofTĐTM/bentonite = 0.5, 4h reaction time and pH = 9. In these conditions, the d001 andorganic content in the product respective is 37.967Å, 32.33%. IR method showed thatthe TĐTM had been in the organoclay. SEM images showed that the organoclaysynthesis layer structure and high porosity.
