In the light of the information presented by Carroll and Mather (1989), a new interpretation is presented for the often‐quoted, smoothed data of Selleck, Carmichael and Sage (1952) for the phase equilibrium in the system water‐hydrogen sulphide. The data of Carroll and Mather show that the liquid‐liquid‐vapour locus extends to higher temperatures than believed by Selleck et al. Experimental data from several sources are correlated using the Stryjek‐Vera (1986a) modification of the Peng‐Robinson (1976) equation of state. It is demonstrated that the fit of the raw data via the equation of state is as good as the smoothing of Selleck et al.
