| 摘 要： | 采用热的无水乙醇作为溶剂将洗衣粉的无机和有机成分分开,利用红外(IR)光谱法进行分析。通过IR分析并经多晶粉末X射线衍射法(XRD)物相分析可以确定洗衣粉无机相主要成分为碳酸钠、硫酸钠以及4A沸石。IR分析表明有机相主要成分为十二烷基苯磺酸钠,核磁共振氢谱(~1H NMR)确认为支链十二烷基苯磺酸钠。

| Abstract: | The inorganic and organic composition of laundry powder were separated by hot ethanol,and studied by infrared spectrometry.As the IR spectrometry and polycrystalline powder X-ray diffraction(XRD) shown,the inorganic components were sodium carbonate,sodium sulphate and synthetic 4A zeolite.IR spectra also demonstrated the main organic component was sodium dodecylbenzene sulfonate.Then nuclear magnetic resonance(~1H NMR) indicated that the main organic composition was branched chain sodium dodecylbenzene sulfonate. |
