The activity coefficients at infinite dilution of hydrocarbon solutes in 1,4-Dicyanobutane (cas 111-69-3) have been measured using medium pressure gas–liquid chromatography. The hydrocarbon solutes were n -pentane, n -hexane, n -heptane, n -octane, n -nonane, n -decane, cyclopentane, cyclohexane, cycloheptane, cyclooctane, 1-hexene, 1-heptene, 1-octene, 1-hexyne, 1-heptyne, 1-octyne, and benzene. The activity coefficients at infinite dilution were determined at T =  (293.15, 298.15, and 303.15) K. The selectivities for benzene and the hydrocarbons are presented and the results indicate that 1,4-dicyanobutane is a good solvent for the separation of an alkane and benzene mixture.
