A linear correlation of enthalpies of vaporization (at T = 298.15 K) of the esters studied with the number n and with the Kovat's indices and has been found. The critical temperatures and pressures of the esters with n = (0 to 6) and n = 8 have been measured by the pulse-heating method with the residence times ranging from (0.03 to 1) ms. Experimental data on the critical properties are compared with the estimations by group contribution methods by Constantinou and Gani and by Marrero and Gani. Both methods considerably underestimate the critical temperatures of the esters studied; however, the method by Marrero and Gani provides the prediction of the critical pressures of the esters with an average absolute error approximately equal to the uncertainty of the measurements. ?? \\\\Expert2\\NBO\\Journal of Chemical and Engineering Data\\2006, v.51, p.1896.pdf |

No literature data are available for the critical properties of phthalates. Since phthalates decompose at temperatures well below their critical temperatures, the method of pulse heating of a wire probe immersed into the liquid under study has been used. The method minimizes the effect of thermal decomposition because residence times are only from (0.035 to 1) ms. The experimental critical properties of phthalates have been compared with the values calculated using the group-contribution methods by Constantinou and Gani and Marrero and Gani. ?? \\\\Expert2\\NBO\\Journal of Chemical and Engineering Data\\2006, v.51, p.1326.pdf |

The method of pulse heating of a wire probe immersed into the liquid under study has been used. Residence times are from (0.03 to 1) ms. The critical properties of diaminoalkanes have been estimated by the group-contribution methods by Joback and Reid, Constantinou and Gani, and Marrero and Gani. These properties have also been calculated using a method based on the assumption that the functions describing the dependence of the critical properties of homologous series on the number of mers in a molecule should be self-similar and provide the scaling behavior for long-chain molecules. The last method provides the best accuracy in calculating the critical properties of diaminoalkanes. For this method, the average absolute errors are equal to 0.4 % for the critical temperature and about 2 % for the critical pressure. ?? \\\\Expert2\\NBO\\Journal of Chemical and Engineering Data\\2006, v.51, p.609.pdf |
D 23 Dashevskaya, E. Gyroscopic Effect in Low-Energy Classical Capture of a Rotating Quadrupolar Diatom by an Ion [Текст] / E. Dashevskaya, I. Litvin, E. D. Nikitin // Journal of Physical Chemistry A. - 2006. - Vol. 110, № 9. - С. 2876-2884 Рубрики: ФИЗИКА Кл.слова (ненормированные): GYROSCOPIC EFFECT Аннотация: The low-energy capture of homonuclear diatoms by ions is due mainly to the long-range part of the interpartner potential with leading terms that correspond to charge?quadrupole interaction and charge-induced dipole interaction. The capture dynamics is described by the perturbed-rotor adiabatic potentials and the Coriolis interaction between manifold of states that belong to a given value of the intrinsic angular momentum. When the latter is large enough, it can noticeably affect the capture cross section calculated in the adiabatic channel approximation due to the gyroscopic property of a rotating diatom. This paper presents the low-energy (low-temperature) state-selected partial and mean capture cross sections (rate coefficients) for the charge?quadrupole interaction that include the gyroscopic effect (decoupling of intrinsic angular momentum from the collision axis), quantum correction for the diatom rotation, and the correction for the charge-induced dipole interaction. These results complement recent studies on the gyroscopic effect in the quantum regime of diatom?ion capture \\\\Expert2\\NBO\\Journal of Physical Chemistry A\\2006, v.110 p.2876.pdf |

The method is based on the hypothesis of functional self-similarity and the scaling behaviour of the critical constants of long-chain molecules. Equations for calculating the critical temperatures and pressures of the homologous series with the common formula H(CH2)nR, where R is a radical have been obtained. The parameters of the equations have been determined from experimental data for six homologous series. The presented method allows predicting the critical temperatures or pressures of any member of a homologous series of the given type if the critical temperature/pressure of one substance, which belongs to this series, is known. The proposed method provides better accuracy in comparison with currently used group-contribution methods for most of the homologous series considered. \\\\Expert2\\NBO\\Fluid Phase Equilibria\\2005. v.235, p.1-6.pdf |
