Smectites quaternary ammonium cations

Fig. 2. Diagram showing the intercalation of compact quaternary ammonium cations, such as trimethylphenylammonium (TMPA) into different smectites, giving rise to type I organoclays with a basal spacing of about 1.5 nm. SWa is a high-charge nontronite (iron-rich smectite) and SAz is a high-charge montmorillonite, while SAC is a low-charge montmorillonite. After Jaynes and Boyd (1991b). Fig. 2.

Molecular weight. In most cases, organocations of higher molecular weight are adsorbed on exchange sites with higher selectivity. For example, the order of preference for a series of quaternary ammonium cations on smectite is... [Pg.358]
