Abstract

The invasion of lithium chloride into the anion exchanger Dowex-1X8-Cl from, and the coincident swelling of the resin in, aqueous methanol, ethanol, 1-propanol, and acetone has been measured. The data are compared with the invasion of hydrogen chloride in similar systems, and with the swelling in the absence of electrolyte, in order to elucidate the effect of the solvent composition on the invasion, and of the invasion on the total and selective swelling. Some data on the swelling in aqueous 2-propanol and allyl alcohol are also shown. It is concluded that the extent of ion pairing of the invading electrolyte, and of the fixed ion of the exchange site with the counterion, is the main factor determining the invasion and the swelling in the presence of the electrolyte.
