Vermiculite was reacted with aliphatic diamines (ethyl-, propyl-, butyl- and hexyldiamines). The products were characterized by elemental analysis, infrared spectroscopy and X-ray diffraction. The amounts of amines adsorbed were 0.89, 0.86, 0.79, and 0.68 mmol g(-1), respectively, for NH2(CH2)(2)NH2 where n=2, 3, 4, 6. The basal spacings of the intercalated vermiculites varied between 1.28 and 1.47 nm. (C) 2005 Elsevier B.V. All rights reserved.
