| 摘 要： | 分别采用硅胶柱色谱法和溶剂抽提,分离优质塑料抛光膏中的油脂和磨料部分。油脂部分依次以石油醚、苯、氯仿、乙酸乙酯、丙酮、乙醇为淋洗剂进行洗脱,利用红外光谱、核磁共振光谱法对所分离组分进行了结构鉴定。磨料部分通过原子发射光谱和X射线衍射法进行金属元素及形态分析。通过上述光谱法确定了该塑料抛光膏的化学组成和结构。

| Abstract: | Silica gel column chromatography and solvent extraction were used to separate grease and abradant in a kind of excellent polishing paste for plastics,respectively.The compositions of grease were eluted with petroleum ether,benzene,chloroform,ethyl acetate,acetone,ethanol and characterized by means of IR and NMR spectroscopy.The metal elements and forms of abradant were analyzed by AES and XRD.With these spectral methods,the chemical composition and the structure of the polishing paste for plastics were iden... |
