【摘要】 应用反气相色谱法研究了聚乙二醇和若干溶剂的相互作用。实验表明以表面处理多孔硅胶为担体,为获得准确的保留体积,需考虑作固定相在担体上涂布量外推。据此计算出相互作用参数X和 ,可和静态蒸汽吸附法或混合体积测定等所得数据相比,并反映了聚乙二醇和溶剂相互作用的某些特点。更多还原

【Abstract】 The interactions of polyethylene glycol (PEG) with some solvents were studied by inverse gas chromatography with surface-treated porous silica as the support material. The retention volume of solvent probe was determined after considering its dependence on the coverage of PEG on the support. The interaction parameters so far obtained were found to be in good accordance with the literature data from static measurements and reflect some characteristic points of the interactions between PEG and solvents.更多还原
