Miscibilities of various hydrocarbons in systems containing n-butanol and aqueous solutions of sodium p-cymenesulfonate (sodium-2-methyl-5-isopropyl-benzenesulfonate) (2.5 moles/kg H/sub 2/O) have been determined at 25 C. The hydrocarbons included aliphatic hydrocarbons, cyclohexane, aromatic hydrocarbons, and various hydrocarbon mixtures. The amount of n-butanol required to achieve miscibility increases with increasing chain length of the aliphatic hydrocarbons and with an increasing number of alkyl carbons on the benzene ring of the aromatic hydrocarbons. The 2-phase region with cyclohexane is smaller than with n-hexane, and similar to that with butylbenzene. For mixtures of 2 hydrocarbons, the amount of n-butanol required seems to vary linearly with weight fraction of the hydrocarbon components.
