Limited Solubility and Critical Exponents for Some Indole + Hydrocarbon Systems

Abstract

The solubility of indole n-octane, n-decane and n-dodecane has been measured at several temperatures. The three systems exhibit limited solubilities with upper critical solution temperatures. The critical exponents of the three systems, evaluated from the experimental data, are found to be the same within the limits of experimental error: β = 0.50 ± 0.4.
