高等化工热力学 Advanced Chemical Engineering Thermodynamics 2007年11月 Importance？ One of the most important courses in the chemical engineering curriculum, Thermodynamics is a cornerstone of chemical engineering. What is Chemical Engineering thermodynamics? 热力学解决问题的框架 针对该问题的普遍关系式 足够数量的强度性质以表征所研究的系统 输入独立变量 输出所需解决的变量 总之：热力学（I) 已经建立不同宏观性质间的普遍关系，但为了得到针对某一具体体系的有用结果，必须输入具体体系的特性／特征数据 Traditional Chemical Engineering Modern Thermodynamics New areas and systems: Material Science, Biological Science and technology Environmental Science Others New technologies of separation PSA (Pressure Swing Adsorption) Supercritical Extraction and Chromatography Membrane Separation Others Molecular Structure and Property: Product Engineering Ind. Eng. Chem. Res., 41 (8), 1917 -1919, 2002. New requirement -product engineering The product engineers need the ability to predict the effects of a proposed change in molecular structures on the molecular properties, so that they would be able to manipulate the material to converge the desired properties to the target values and to know where to look for new material with desired properties Molecular-Level Molecular-level study in chemistry and chemical engineering is a very important areas in the 21st century, Statistical mechanics shows how the properties of macroscopic systems are related to the properties of the molecules of which they are composed, All properties are dependent upon molecular structure and the interaction between molecules intellectual core of product engineering the science of molecular structure-property relations A product needs to have certain properties, which are required for it to function with satisfaction For example, a refrigerant, depends on boiling point, heat of vaporization, nontoxic and nonflammable, and affordable pricing. The principal intellectual challenge how does an innovative product engineer find or design a molecular structure or compound a mixture with the required propertie
