Analytical equipment for phase equilibrium research on three specific projects will be acquired. The first project has to do with the thermodynamic properties needed to make intelligent choices for industrial water pollution reduction, water remediation, and for estimating the fate, transport and bioaccumulation of chemicals. The second project concerns the reduction of automobile air pollution emissions by the reformulation of gasolines, i.e., the production of "clean" gasoline. The key blending components in such gasolines may be oxygenated hydrocarbons, such as methyl tertiary butyl ether (MTBE) as these compounds have been found to increase octane numbers of gasolines while reducing polluting emissions of the oxides of nitrogen and carbon monoxide. Research currently underway, for which some equipment is needed, is on the phase behavior of the oxygenate + hydrocarbon systems. The third project is aimed at developing a predictive design model for the purification of biomaterials using aqueous two- phase two-polymer systems. The experimental portion of this research deals with dependence of the liquid-liquid phase splitting and the biomolecule partitioning on variables such as polymer molecular weight and molecular weight dispersion, temperature, pH, ionic strength buffer salts used, etc.

三组分相平衡研究用分析设备 将收购具体项目。 第一个项目必须 与热力学性质有关， 减少工业水污染的明智选择， 水补救，并估计的命运，运输和 化学物质的生物积累。 第二个项目涉及 减少汽车空气污染排放 汽油的重新配制，即，生产“清洁” 汽油 这种汽油中的关键调合组分可 可以是氧化烃，例如甲基叔丁基 醚（MTBE），因为这些化合物已被发现增加 汽油的辛烷值，同时减少污染排放 氮和一氧化碳的氧化物。 研究 目前正在进行，需要一些设备， 三种烃类体系的相态特征。 第三个项目旨在开发一种预测性设计 模型的纯化生物材料使用含水双- 两相聚合物体系。 这个实验的一部分 研究涉及液-液相的依赖性 分裂和生物分子分配的变量， 作为聚合物分子量和分子量分散体， 温度、pH、所用缓冲盐的离子强度等。
