Experimental Data
The three phase critical point was reported to be 529.4 K, 8.025 Mpa and x1 = 1.748 × 10-3 (0.82 g(1)/100 g sln, compiler).
The authors also report equations fitted to their own and litrature data over the range 273-529 K, viz.
ln x1 = -209.11689 + 8325.49/T + 29.8231 ln T
ln x2 = -62.7645 - 654.027/T + 9.99967 ln T
