Abstract: A Study on the Mass Spectrometry of γ-ChloropropyltrialkoxysilanesLin jimao(Department of Chemistry,Shandong University, Jinan 250100, China)Abstract:Mass spectra of five synthesizedΥ-chloropropyltrialkoxysilanes were studied.According to relative intensity of isotopes of chlorine and silicon,the compositions of fragments and fragmentation regularities of mass spectra were inferred.Keywerds:γ-chloropropyltrialkoxysilane, mass spectra,isotope
