1) 1H NMR spectra ~1H NMR谱 1. The1H NMR spectraof BPHA and Zn( II ) - BPHA have been determined in the pD range 0. 测定了各pD值下BPHA[BPHA是N,N’-bis(2-aminoethyl)-1,3-propanediamine hexaaceticacid的简称,中文名称为二胺乙基丙二胺六乙酸]和Zn~(2+)-BPHA的~1H NMR谱。
1H-NMR谱 1. Each fraction was analyzed qualitatively by1H-NMR spectra,then the aromatic fraction was characterized using gas chromatograph/mass spectrometer(GC-MS). 通过1H-NMR谱图对各族组分的切割点的准确性进行了定性分析,并用色-质联用对循环油的芳烃组分进行了分析,初步确定了基本组成,为煤液化油的...
