Heteroatomic compositional analysis of Venezuela Orinoco AR and the visbreaking product by negative ion ESI-FT-ICR MS
高分辨质谱解析委内瑞拉奥里常渣减黏反应杂原子化合物组成变化

Molecular transformations of heteroatomic compounds during visbreaking of Venezuela Orinoco AR were studied by ultrahigh-resolution negative ion electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry(ESI-FT-ICR MS).The results indicated that the relative abundance of O2,O1,N1O2,S1,O1S1 and O2S1 are decreased or even disappeared,but those of N1,N2,N2O1,N2S1,N3,N3O1,and N1S2 are increased after the visbreaking.The highest relative abundance is O2 class in Venezuela Orinoco AR,whil...
