Synthesis of Organo-montmorillonite by Intercalation Reaction and its Kinetic Study

ABSTRACT

A stable intercalation complex was formed by adsorption of alcanol (ROH, R; $C_{10}H_2$, $C_{12}H_{25}$, $C_{14}H_{29}$) on the surfaces of Yongil bentonite in which the interlayer cation had been exchanged by n-decylammonium ion $(C_{10}H_{21}NH_3^+)$ The layer charge density calculated from the increaments of basal spacings was 0.34 per unit chemical formula. Thermochemical properties of synthesized $C_{10}H_{21}NH_3^+$ montmorillonite were studied by means of DSC, TGA, DTG, Thermal analysis showed two steps of desoption behavior of $C_{10}H_{21}NH_3^+$ ion namely nonyl $(CH_3(CH_2)_8$ decomposition reaction of 40$0^{circ}C$ and methyleneammonium decomposition reaction of 78$0^{circ}C$ The activation energy of nonyl decomposition reaction of $C_{10}H_{21}NH_3^+$ -montmorillonite respectively.
