Sylodex Bentonites —: Gelling and Anti‐sedimentation Agents

Abstract

Organophilic Sylodex Bentonites are organically treated forms of the clay mineral montmorillonite. The latter is present in the form of microscopically small platelets. The platelets are characteristic of the crystalline structure of the montmorillonite. The chemical composition is that of an aluminium hydrosilicate in which the silicon, aluminium and oxygen atoms are arranged in 3 layers (see Fig. 1). The outer layers consist of SiO2‐tetrahedra and the inner layers of (AlO4(OH)2) octahedra. An idealized initial structure of the precursor of montmorillonite exhibits the following neutral formula:
