俄罗斯减压馏分油中硫化物的分离富集及结构鉴定

Separation and identification of sulfur compound in Russia decompression distillated oil by ligand exchange chromatography

采用PdCl2配位色谱法对俄罗斯减压馏分油中的硫化物进行了分离和富集。结果表明,PdCl2配位色谱法是分离减压馏分油硫化物的有效手段,不同构型的硫化物在PdCl2配位色谱柱上的保留行为存在很大的差异。运用色谱质谱技术对分离出的硫化物结构进行的鉴定结果表明,俄罗斯减压馏分油中含有烷基环状硫醚、烷基苯并噻吩、烷基二苯并噻吩和烷基萘苯并噻吩等类硫化物。

The ligand exchange column chromatography using silica gel impregnated with palladium chloride was employed to separate,enrich and evaluate the sulfur compound of Russian decompression distillated oil.The results show that the ligand exchange chromatography is an effective method to separate sulfur from heavy oil.The identification of the sulfur structure by gas chromatograph-mass spectrometer indicates that alkyl cyclic sulfide,alkyl thiophene,alkyl dibenzothiophen and alkyl naphthobenzothiophene are the main types of sulfide compounds in Russian decompression distillated oil.
