摘要
研究了一系列α-羟基膦酸酯的电喷雾质谱裂解方式,发现该类化合物的加氢和加钠离子具有不同的裂解方式.加氢裂解的特点是容易失去水分子和亚磷酸碎片,这可能是此类化合物可用于阻燃剂的原因;加钠裂解的特点是失去一分子硝基和苯甲醛后,接着失去一分子丁醇,形成m/z143碎片.根据这些碎片,提出了其可能的裂解途径.
The fragmentation pathways of α-hydroxy phosphonates are studied with electrospray ionization mass spectrometry(ESI-MS).Some different fragmentation pathways between + and + are observed in the ESI-MS/MS.The striking feature of the MS/MS spectra of the + ions is the expulsion of water and H3PO3 group.This maybe is a reason for their using in flame retardance.The main fragmentation pathway of + is losing NO2 and C6H5CHO,then leaving a HOC4H9 to form a fragment ion at m/z 143.The mechanism of the possible fra...
