Three-phase equilibria in (ethane + pentacosane)

摘要: Abstract In the critical region of ethane liquid is not miscible in all proportions with n -paraffins above heptacosane. If -paraffin has its triple point this temperature occurrence a quadruple (solid + vapour): (s B l 1 2 g) to be expected. This paper reports on four three-phase equilibria originating such (ethane pentacosane). The measurements were performed from about 300 315 K and pressures up 8.0 MPa applied. A striking feature our experimental technique that entire p ( T ) behaviour interest could determined only one overall composition mixture. From results location pentacosane vapour) derived: (4.67 ± 0.03) (303.76 0.15) K.
