Description

The integral heats of solution of Bu4NI in dimethylsulfoxide (DMSO) were measured at 298.15, 313.15, and 328.15 K and concentrations from dilute to saturation. The standard enthalpies and heat capacities of solution and solvation of Bu4NI in DMSO at various temperatures and the C-barp0(Bu4N+) value at 298.15 K were calculated. The obtained and literature data were used to consider the influence of the nature of solvents on ΔsolHm(Bu4NI) and of the electrolyte on ΔsolHm in dimethylsulfoxide at 298.15 K. The dynamic viscosity and density of the Bu4NI-DMSO system were determined at various concentrations and temperatures. The Eyring equation was used to calculate the activation energy of viscous flow at all the concentrations studied

Abstract (Russian)

Приведены значения интегральных теплот растворения Bu4NI в диметилсульфоксиде при 298.15, 313.15, 328.15 К от разбавленной области концентраций до насыщения. Рассчитаны стандартные изменения энтальпии и теплоемкости при растворении и сольватации Bu4NI в ДМСО при различных температурах, а также значение C-barp0(Bu4N+) при 298.15 К. На основании полученных и литературных данных рассмотрено влияние природы растворителя на ΔpcHm(Bu4NI) и электролита на ΔрсHm в диметилсульфоксиде при 298.15 К. Представлены значения динамической вязкости и плотности системы Bu4NI - ДМСО при различных концентрациях и температурах. На основании уравнения Эйринга рассчитаны значения энергии активации вязкого течения при всех изученных концентрациях
