Abstract

Our two previous articles__G. S. A. van Welie__ and G. A. M. Diepen, Rec. trav. chim. 80, 659 (1961).

Idem, ibid., 80, 666 (1961).

and some supplementary observations enabled us to derive a number of sections and projections of the P‐T‐x space model of the ethylene‐naphthalene system, within the following limits of measurement: 0 to 1000 atm, 0 to 100 moles % naphthalene and 20° to 115°. An important result of our discovery is that the critical conditions of the second critical point are: P = 174.0 atm, T = 52.1° and x = 17 moles % ± 0.5.

On the L~2~ = G curve we have found a pressure maximum at 244 atm and 195°.

## Abstract V‐T measurements carried out on the ethylene‐naphthalene system at constant composition are described. The measurements also provide data on the saturation volumes of solutions of naphthalene in supercritical ethylene.
