ABSTRACT

Physicochemical properties and nature of the interactions in solutions of ammonium nitrate in water or lower alcohols (methanol, ethanol and n-propanol) have been investigated. The density was measured in the temperature range from T = (293.15 to 313.15) K for {NH4NO3 + H2O} and {NH4NO3 + MeOH} binary mixtures and in temperature range T = (293.15 to 323.15) K for {NH4NO3 + EtOH} and {NH4NO3 + n-PrOH} at atmospheric pressure (p = 1*105 Pa). From experimental densities, the apparent molar volumes and partial molar volumes in a whole concentration range, as well as at infinite dilution were obtained. According to volumetric results obtained for solutions of NH4NO3 in short-chain alcohols and water, values for the electrostrictive volume of the ammonium nitrate, V-el, solvation number, n, and ionic transfer volumes between solvents, deltatV-o(NH4NO3,w-greater thans), are obtained and discussed. Based on these values and features the electrolyte effect on surrounding molecules were estimated and discussed.
