摘要
用Anton Paar DSA 5000M测量了聚乙二醇(PEG-200和PEG-600)在不同温度和浓度下在d -甘露醇水溶液中的密度和声速。利用实验得到的密度和声速数据，计算了分子间自由长度、声阻抗、绝热压缩系数、Wada常数、Rao常数和Vander Waal常数等理论参数，从而更好地了解聚乙二醇与d -甘露醇溶液之间的分子相互作用。
Study of Molecular Interaction of PEG-200 and PEG-600 in Aqueous D-Mannitol Solutions at Different Temperatures
The density and speed of sound for polyethylene glycols (PEG-200 and PEG-600) in an aqueous solution of D-Mannitol have been measured by Anton Paar DSA 5000M at different temperatures and concentrations. Experimentally obtained data of density and speed of sound are employed to calculate various theoretical parameters such as intermolecular free length, acoustic impedance, adiabatic compressibility, Wada's constant, Rao's Constant, and Vander Waal's constant, which gave the better insight into molecular interactions between the polyethylene glycols and D-mannitol solutions.
