Research Equipment Proposal - Isothermal Flow Calorimeter for Heats of Mixing of Liquid Systems

在这项设备补助金中，将使用等温流动量热计系统测量许多液体混合物在宽温度和压力范围内的混合热。特别强调的是放在二元和三元液-液系统，并对液体混合物含有高分子量的醇和芳香族化合物。从这个项目中得到的基本数据将被用来建立精确的模型，以确定部分互溶体系的相行为。实验数据也将获得几个液-液系统的热能储存的潜力，由于在混合热的大的变化低于和高于其临界溶液温度。含有高分子量化合物的混合物的数据将用于扩展和改进用于确定高温高压下极性混合物的相行为和其他热力学性质的分析程序。

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.
