ABSTRACT
An apparatus has been designed and constructed to measure mutual solubilities of (water + hydrocarbon). The solubility of water in toluene, cyclohexane, methylcyclohexane, ethylcyclohexane, and (cis + trans)-1,2- dimethylcyclohexane were determined at temperatures ranging from (30 to 180) deg C. Measurements obtained for toluene show good agreement with literature values and allow us to validate this new method. As expected, increasing the temperature increases the solubilities of water in the alkylcyclohexanes. Furthermore, the solubility of water in alkylcyclohexanes increases with the number of carbon atoms.
