The solubility of gas in liquid medium is important for developing and studying of three phase slurry reactor. In an agitated autoclave equilibrium gas solubilities ( C *) of O 2,CO 2,C 2H 4 and N 2 in high boiling point solvent No.2 of three phase slurry reactor were measured at various temperature 60～230°C and pressure 0.05～1.2MPa. According to the change of pressure during the pure gas dissolution in the solvent, solubilities for O 2,CO 2,C 2H 4 and N 2 were calculated. Under operating conditions, the equilibrium solubilities of O 2,CO 2,C 2H 4 and N 2 in the solvent increased with increasing pressure, decreased with increasing temperature. The relationships between solubility coefficients for O 2,CO 2,C 2H 4 and N 2 and temperature were correlated. The solubility coefficients of CO 2 and C 2H 4 increased with increasing temperature, but the solubility coefficients of O 2 and N 2 decreased with increasing temperature. The result is useful for the design and development of three phase slurry reactor.
