GusevAbstract:The vapor pressures of the 1,4-dioxane + Tetrabutylammonium nitrate and water + Tetrabutylammonium nitrate systems have been measured at different salt molalities. The vapor pressures of the 1,4-dioxane + water + Tetrabutylammonium nitrate system have also been measured at 11 constant salt molalities (0.100, 0.250, 0.500, 0.750, 1.000, 1.500, 2.000, 2.500, 3.000, 3.500, and 4.000) mol·kg−1. These systems have been studied at (288.15, 298.15, and 308.15) K with a modified Othmer still. The electrolyte nonrandom two-liquid model was used for the calculation of the activity coefficients of solvents in the binary systems.

synthesis of triphenyl phosphate and benzyl benzoate with phase transfer catalyst in a heterogeneous liquid liquid reaction system
Industrial & Engineering Chemistry Research, 1994Co-Authors: Satoru Asai, Mitsunori Tanabe, Hidemi Nakamura, Kenji SakamotoAbstract:The synthetic reactions of triphenyl phosphate from diphenylphosphoryl chloride and sodium phenoxide and of benzyl benzoate from benzyl chloride and sodium benzoate with phase-transfer catalyst were studied in a heterogeneous liquid-liquid reaction system using an agitated vessel with a flat interface. Tetrabutylammonium bromide and 1,2-dichloroethane were used as a catalyst and a solvent, respectively. The behavior of the observed overall reaction rates was explained well by the proposed model. The overall reaction rates were proportional to the organic-phase interfacial concentrations of the actual reactants, Tetrabutylammonium phenoxide for the synthesis of triphenyl phosphate and Tetrabutylammonium benzoate for that of benzyl benzoate. Their interfacial concentrations were a unique function of the concentrations of Tetrabutylammonium bromide and the respective sodium salts. The intrinsic reaction rate constants, for the synthetic reactions of triphenyl phosphate and benzyl benzoate, which were evaluated by fitting the rate data to the model prediction, were 2.33X10 6 and 2.56 m 3 /kmol.s at 303K, respectively

Distribution and dissociation equilibria of phase-transfer catalysts, Tetrabutylammonium salts
Industrial & Engineering Chemistry Research, 1993Co-Authors: Satoru Asai, Mitsunori Tanabe, Hidemi Nakamura, Kenji SakamotoAbstract:The distribution and dissociation equilibria of phase-transfer catalysts, Tetrabutylammonium salts (Q + Br, Q + Cl - , Q + OH - ), were measured at 303 K for the systems of 1,2-dichloroethane-water and aqueous electrolyte solutions. Furthermore, those of Q + C 6 H 5 O 2 - and Q + C 6 H 5 CO 2 - were evaluated at 303 K from the system of Q + Br - /1,2-dichloroethane/aqueous C 6 H 5 ONa and C 6 H 5 CO 2 Na solutions, respectively. The equilibrium relations varied greatly depending on the kinds of anionic group of the Tetrabutylammonium salts. The evaluated distribution coefficients of Tetrabutylammonium salts were correlated as a function of the ionic strength in the aqueous phase. The dissociation constants of Tetrabutylammonium salts were substantially independent of the ionic strength
