Competitive hydration of quinazoline at the montmorillonite-water interface.
Ultraviolet spectroscopic analyses of suspensions of quinazoline and Na(+)-saturated montmorillonite have indicated that covalent hydration of the monovalent organic cation is inhibited at or near the clay surface. A similar lack of hydration was observed in solutions of quinazoline and high-ionic-strength calcium chloride. The inhibition is attributed to a local competition between quinazoline and the inorganic cations for water of hydration.
