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

在此设备补助中，将使用等温流量量热计系统在广泛的温度和压力范围内测量许多液体混合物的混合热。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。从这个项目得到的基本数据将被用来建立精确的模型来确定部分混相体系的相行为。实验数据还将获得几个液-液系统，由于在其临界溶液温度以下和高于其临界溶液温度的混合热的巨大变化而具有热能储存的潜力。含有高分子量化合物的混合物的数据将用于扩展和改进分析程序，以确定极性混合物在高温高压下的相行为和其他热力学性质。

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.
