In this study, the behaviors of adsorption of six different quaternary ammonium salts onto montmorillonite (Mt) have been investigated. One of six cationic surfactants is branched (tetrabutylammonium bromide (C4)4ABr) and the others are linear (with five different hydrocarbon chain lengths, i.e. C16TABr, C14TABr, C12TABr, C10TABr, and C8TABr).The organoclays were characterized by spectroscopic techniques...
Few studies have explored the change in thermal stability of poly(oxypropylene) (POP) ammonium ions after intercalation, even though several studies have focused on the modification of montmorillonite (Mt) with POP amine hydrochloride. The purpose of the present study was to understand the effect of chain length of POP amine hydrochlorides on the basal spacing of modified Mt, and the amount and thermal...
