Ключевые слова (''Своб.индексиров.''): critical temperatures
Аннотация: The critical temperatures and pressures of phthalates with the straight side alkyl chains C6H4?1,2-[COO(CH2)nH]2 (n is from 1 to 11) as well as bis(2-ethylhexyl) phthalate have been measured. 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. ??

Ключевые слова (''Своб.индексиров.''): liquid-vapor interface--molecular dynamics--pressure tensor
Аннотация: Tolman parameter delta(T), which determines the first correction to surface tension for the interface curvature, is calculated in molecular-dynamic experiments performed for Lennard-Jones fluid within the temperature range from the critical to the triple point (and slightly below). It is shown that parameter delta(T) is positive and slightly depends on temperature; its absolute magnitude is no larger than 0.1-0.2 molecular diameters and does not coincide with the distance between the equimolecular dividing surface and the surface of tension in a flat interfacial layer, as calculated through the first moment of the pressure tensor. The results of the moleculardynamic experiments are compared with the delta(T) values calculated in terms of the extended version of the van der Waals theory of capillarity. It is established that taking into account terms of higher orders than the squared density gradient in the expansion of the free energy of an inhomogeneous system does not reverse the negative sign at delta(T) and slightly affects its value

Ключевые слова (''Своб.индексиров.''): lennard-jones fluid--van-der-waals theory --molecular dynamics
Аннотация: Computer experiments on simulation of thermodynamic properties and structural characteristics of a Lennard-Jones fluid in one- and two-phase models have been performed for the purpose of checking the base concepts of the van der Waals theory. Calculations have been performed by the method of molecular dynamics at cutoff radii of the intermolecular potential rc,1=2.6σ and rc,2=6.78σ. The phase equilibrium parameters, surface tension, and density distribution have been determined in a two-phase model with a flat liquid-vapor interface. The strong dependence of these properties on the value of rc is shown. The p,ρ,T properties and correlation functions have been calculated in a homogeneous model for a stable and a metastable fluid. An equation of state for a Lennard-Jones fluid describing stable, metastable, and labile regions has been built. It is shown that at T~1.1 the properties of a flat interface within the computer experimental error can be described by the van der Waals square-gradient theory with an influence parameter κ independent of the density. Taking into account the density dependence of κ through the second moment of the direct correlation function will deteriorate the agreement of the theory with data of computer simulation. The contribution of terms of a higher order than (∇ρ)2 to the Helmholtz free energy of an inhomogeneous system has been considered. It is shown that taking into account terms proportional to (∇ρ)4 leaves no way of obtaining agreement between the theory and simulation data, while taking into consideration of terms proportional to (∇ρ)6 makes it possible to describe with adequate accuracy all the properties of a flat interface in the temperature range from the triple to the critical point

Аннотация: This paper reports new experimental data for the specific enthalpy of the solution of isobutane (refrigerant R600a, CH(CH3)2−CH3, CAS Registry No. 75-28-5) with mineral naphthenic compressor oil WF 15A. The experimental data were obtained in the temperature range from (273 to 355) K by a mixing method realized in an ice calorimeter. The behavior of the temperature and weight fraction dependencies of the enthalpy for the refrigerant−oil solution (ROS) of R600a and mineral compressor oil WF 15A have been examined

Ключевые слова (''Своб.индексиров.''): dielectric permittivities--flexible molecules--ir absorption coefficient
Аннотация: Nitrate ion adsorption by water clusters is studied using the molecular dynamics method combined with a polarizable model of flexible molecules. It is established that successive addition of one to six NO 3 - ions to an (H2O)50 cluster decreases the averaged electrical potential related to the center of masses of water molecules. The (H2O)50 cluster retains its thermodynamic stability, provided that no more than three nitrate ions are added to it. After NO 3 - ions are adsorbed, the real and imaginary components of the dielectric permittivity and the intensity of the Raman spectrum decrease, while the intensity of the IR absorption spectrum increases. Moreover, ion adsorption by the water cluster reduces the IR absorption coefficient and refractive index

Ключевые слова (''Своб.индексиров.''): heat emission--heteroclusters--ir absorption
Аннотация: The interaction of IR radiation with water clusters that have absorbed NO 2 molecules is studied by the molecular dynamics method in terms of the polarizable model. Induced dipole moments of H 2O and NO 2 molecules diminish during the addition of one to six NO 2 molecules to (H 2O) 50 cluster. The integral intensity of IR absorption by a system consisting of (NO 2) i(H 2O) 50 heteroclusters with 1 ≤ i ≤ 6 decreases, whereas the power of heat emission rises as compared with an (H 2O) n system. The decrease in the IR absorption and the increase in the IR emission by water clusters with the capture of NO 2 molecules are nonmonotonic. The absorption of NO 2 molecules by water clusters causes a noticeable reduction in the intensity of the first peak and the confluence of the fourth and fifth peaks in the Raman spectrum
