✦ Synopsis
The concentration and temperature dependences of the specific mass and of the transport properties of molten mixtures of zinc chloride and of N-methylpyridinium chloride have been investigated. The specific mass linearly decreases with the temperature at all compositions of the mixture. In the limited temperature range available in this study (421-473 K), the temperature dependence of the transport properties is adequately described by the Arrhenius law. The specific mass regularly increases from pure Nmethylpyridinium chloride to pure zinc chloride. The equivalent conductance generally decreases with the concentration of zinc chloride in the melt but remains practically constant from Xx,,ct, = 0.33 to Xxr,~, = 0.50. The viscosity isotherms show a maximum value at XgrrcL, T 0.33 and a minimum for Xx,,,-,, = 0.45. The discussion of the results is founded upon the structural properbes of the melts and takes into account the Walden's relation between the viscosity and the equivalent conductance.
