Form factor analysis of differential thermal analysis curve for organic montmorillionite

    Corresponding author: CUI Hui-wang1

Abstract: Organic montmorillionite(OMMT)was prepared from octadecyl trimethyl ammonium bromide(STAB),dioctadecyl dimethyl ammonium bromide(DOAB),trioctadecyl methyl ammonium bromide(TOAB)and montmorillionite(MMT),and then studied by thermo gravimetry and differential thermal analysis(TG-DTA). Results showed that the intercalation of OMMT was good,and the pyrolysis kinetic equations of MMT/STAB,MMT/DOAB and MMT/TOAB differed because of the different arrangement of STAB,DOAB and TOAB in layers of OMMT. Form factors(Ф) of DTA curves calculated from pyrolysis kinetics of OMMT indicated that the symmetry of DTA curve of MMT/STAB was better than that of MMT/DOAB and MMT/TOAB,and were identical with the DTA curves in TG-DTG-DTA.[Ch,5 fig. 1 tab. 15 ref.]
