“…The central quantity here is the solubility parameter 8, which is defined as the square root of the cohesive energy density of the liquid; it is usually calculated from the energy of vaporization: More recent work based on solubility parameters is due to Sagara et al, 277 Linford and Thornhill, 85278 Brelvi, 279 and Sebastian et al 76 The latter authors develop a correlation for Downloaded by [Michigan State University] at 14:37 04 February 2015 the solubility of hydrogen in hydrocarbon solvents at temperatures from 310 to 700 K and pressures up to 30 MPa. This kind of information is required for engineering design and analysis of reaction kinetics of hydrofining processes.…”
