DETERMINATION OF VAPOR PRESSURE, WATER SOLUBILITY, GAS-WATER PARTITION COEFFICIENT PGw, HENRY'S LAW CONSTANT, AND OCTANOL-WATER PARTITION COEFFICIENT Pow OF 26 ALKYL DINITRATES

摘要: Abstract The octanol-water partition coefficient (POW), water solubility (SH2O) and vapor pressure of the sub cooled liquid (p 0 l ) have been determined for 26 alkyl dinitrates. coefficients range from log POW = 1.4 1,2-ethyl dinitrate to 5.9 1,2-decyl dinitrate, respectively. experimental results agree, within ±- 0.15 units, with calculations by increment method according Hansch Leo. Water solubilities are in 154 mol m−3 (23.1 g L−1) 0.002 (0.5 mg pressures P0 150.5 Pa 1,2-propyl 0.01 1,10-decyl dinitrate.
