Anomalies in the Ethylene Glycol Solvation Technique Used in X-Ray Diffraction

  • G. W. Kunze


X-ray diffraction results are presented to show that some montmorillonites will not retain two layers of ethylene glycol in the interiayer space when dried under atmospheric conditions. Diffraction data obtained from such samples of montmorillonite may erroneously be attributed to mixed layer minerals. Studies have shown however that this difficulty may largely be overcome by initially saturating the sample with ethylene glycol by the vaporization technique described, after which the sample is placed in a saturated atmosphere of ethylene glycol for a period of 12–24 hours to come to equilibrium and then irradiated.
