The influence of various cations on the catalytic properties of clays.

M Paecht-Horowitz.   

Abstract

Polymerization of alanine adenylate in the presence of various clays in their Na form gave increasing degrees of polymerization in the following order: montmorillonite less than nontronite less than hectorite. With montmorillonite, presaturated with different cations the order was: Mg less Ca less than Fe less than Al less than Na. From all these clays, hectorite was the only one to enable also some polymerization of lysine.
