In this equipment grant, heats of mixing will be measured for a number of liquid mixtures for wide ranges of temperature and pressure with an isothermal flow calorimeter system. Particular emphasis is placed on binary and ternary liquid-liquid systems, and on liquid mixtures containing high molecular weight alcohols and aromatic compounds. The basic data resulting from this project will be utilized to developo accurate models for the determination of the phase behavior of partially miscible systems. Experimental data will also be obtained for several liquid-liquid systems with potential for thermal energy storage due to large changes in the heat of mixing below and above their critical solution temperatures. The data for mixtures containing high molecular weight compounds will be utilized to extend and improve analytical procedures for the determination of phase behavior and other thermodynamic properties of polar mixtures at elevated temperatures and pressure.

在这项设备资助中，将使用等温流动热量计系统测量多种液体混合物在较宽的温度和压力范围内的混合热。特别强调二元和三元液-液体系，以及含有高分子量醇和芳香族化合物的液体混合物。这个项目的基本数据将被用来开发精确的模型，用于确定部分相容体系的相行为。还将获得几个液-液体系的实验数据，由于混合热在临界溶液温度以下和以上有很大的变化，因此有可能存储热能。含有高相对分子质量化合物的混合物的数据将被用来扩展和改进分析程序，以确定在高温和压力下极性混合物的相行为和其他热力学性质。
