The amount of ethylene glycol retained by a clay is used as an index of interlayer swelling. Potassium montmorillonites after drying at 100° C show markedly lower glycol retention than do calcium and hydrogen montmorillonites. X‐ray diffraction data indicate that these potassium clays are in part unsolvated between silicate layers, and in part solvated with two layers of ethylene glycol.
