Abstract

A model isotherm is developed that describes the adsorption of methanol and benzene from methanol-benzene mixtures throughout the whole concentration range (molar fraction of methanol from x//1 equals 0 to x//1 equals 1). The clay mineral montmorillonite is used as an adsorbent. The silicate layers are made hydrophobic by exchanging the inorganic gegen ions by alkylammonium ions C//n//cH//2//n//c plus 1 NH//3** plus (n//c equals 10 minus 18). With increasing alkyl chain length (increasing hydrophobicity) the amounts of benzene adsorbed (n//2**s) increase, whereas those of methanol (n//1**s) remain constant.
