✦ Synopsis

In this paper we report activity coefficients at infinite dilution γ ∞ i of {N -methyl-2-pyrrolidinone (NMP), or N ,N -dimethylformamide (DMF), or dimethyl sulfoxide (DMSO) + 1-heptyne, or 1-octyne} using comparative ebulliometry. This work is a continuation of a study on (NMP, or DMF, or DMSO + hydrocarbons). The design of the ebulliometer allows the measurement of three activity coefficients simultaneously with four ebulliometers connected to a common manifold.
