Data20032003-07-01Solubility in Binary Solvent Mixtures: Pyrene Dissolved in Alcohol + Acetonitrile Mixtures at 299.2 KExperimental solubilities are reported for pyrene dissolved in seven binary alcohol + acetonitrile solvent mixtures at 26 C. The alcohol cosolvents studied were 1-propanol, 2-propanol, 1-butanol, 2-butanol, 2-methyl-1-propanol, 3-methyl-1-butanol and 2-pentanol. Results of these measurements are used to test a mathematical representation based upon the Combined Nearly Ideal Binary Solvent (NIBS)/Redlich-Kister equation. For the seven systems tudied, the Combined NIBS/Redlich-Kister equation was found to mathematically describe the experimental solubility data to within an overall average absolute deviation of approximately 1.0 %.pyrene solubilitiesbinary solventsalcohol cosolventsacetonitrile cosolvent48736-7381pyreneC16H101Commercial source1982Not known2Crystallization from solution2992Estimation21-propanolC3H8O1Commercial source199.93Not known2Fractional distillation299.93Gas chromatography32-propanolC3H8O1Commercial source1992Not known2Fractional distillation299.73Gas chromatography41-butanolC4H10O1Commercial source199.83Not known2Fractional distillation299.83Gas chromatography52-butanol, dl-C4H10O1Commercial source1992Not known2Fractional distillation299.73Gas chromatography62-methyl-1-propanolC4H10O1Commercial source199.53Not known2Fractional distillation299.73Gas chromatography73-methyl-1-butanolC5H12O1Commercial source1992Not known2Fractional distillation299.73Gas chromatography82-pentanolC5H12O1Commercial source1992Not known2Fractional distillation299.73Gas chromatography9acetonitrileC2H3N1Commercial source199.83Not known2Fractional distillation299.83Gas chromatography219111Principal objective of the workJCEJCE2/21/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal1Pressure, kPa1013Temperature, K299.241Solvent: Mole fraction9Liquid291001.0042631.149941.0070231.273241.0086531.492741.009931.592441.0098431.690641.0092931.832341.0079431.924541.0068931151.006143319111Principal objective of the workJCEJCE2/21/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal1Pressure, kPa1013Temperature, K299.241Solvent: Mole fraction9Liquid391001.002931.161941.0055531.266241.0068631.490341.0084531.563641.0086231.668441.0082831.840841.0072531.924141.0066331151.006143419111Principal objective of the workJCEJCE2/21/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal1Pressure, kPa1013Temperature, K299.241Solvent: Mole fraction9Liquid491001.0062231.180641.0103441.303741.0121741.524241.0136341.634941.012841.733241.0117941.87741.0088631.937741.0074831151.006143915111Principal objective of the workJCEJCE2/21/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal1Temperature, K299.24Pressure, kPa10131Solvent: Mole fraction9Liquid951001.0043931.171141.0083931.325241.0111841.533941.0122541.634641.0116341.7341.010541.876241.0080731.941241.0069331151.006143916111Principal objective of the workJCEJCE2/21/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal1Temperature, K299.24Pressure, kPa10131Solvent: Mole fraction9Liquid961001.0032631.171441.0064231.307441.0087231.538241.0107241.634141.0105841.724141.0099231.868641.0080231.933141.0069931151.006143917111Principal objective of the workJCEJCE2/21/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal1Pressure, kPa1013Temperature, K299.241Solvent: Mole fraction9Liquid971001.0054631.198141.0099531.370941.0122341.582941.0129641.6641.0125541.760541.0113241.892941.0084931.946141.0073431151.006143911181Principal objective of the workJCEJCE2/21/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal1Temperature, K299.24Pressure, kPa10131Solvent: Mole fraction9Liquid981001.006431.222241.0127441.373341.0151741.56941.0158441.665241.0149541.762641.0128341.8941.0092531.949441.0075131151.0061432111Principal objective of the workVVDTRC7/1/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal11Pressure, kPa2Temperature, K110132299.241.0042639111Principal objective of the workVVDTRC7/1/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal11Pressure, kPa2Temperature, K110132299.241.0061433111Principal objective of the workVVDTRC7/1/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal11Pressure, kPa2Temperature, K110132299.241.002934111Principal objective of the workVVDTRC7/1/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal11Pressure, kPa2Temperature, K110132299.241.0062235111Principal objective of the workVVDTRC7/1/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal11Temperature, K2Pressure, kPa1299.24210131.0043936111Principal objective of the workVVDTRC7/1/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal11Temperature, K2Pressure, kPa1299.24210131.0032637111Principal objective of the workVVDTRC7/1/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal11Pressure, kPa2Temperature, K110132299.241.0054631181Principal objective of the workVVDTRC7/1/20031Mole fractionOther1LiquidDirect value, XLiquidCrystal11Temperature, K2Pressure, kPa1299.24210131.00643
