摘要
采用Pd^(2+)/硅胶络合薄层色谱制备分离重质馏分油中的硫化物,用质谱、红外光谱和气相色谱模拟蒸馏等方法鉴定了硫化物的结构.
S Compounds in heavy distillates (up to 480℃) of petroleum were separated by complex thin-layer chromatography with Pd^(2+)/silica gel plate. Thus,130 μ1 solution of 50% oil sample in 30～60℃ petroleum ether was spotted on the plate, developed with 20% of CH_2Cl_2 in n-hexane. The sample was separated into tetrahydrothiophenes, thiophenes and non-sulfur aromatics according to the interaction forces of Pd^(2+) toward S in various compounds.The struc-tures of S compounds from TLC were identified mainly to be alkyl tetrahydrothiophene, alkyl octahydro-benzothiophene, alkyl thiophene, alkyl tetrahydro-benzothiophene, alkyl octahydro-dibenzothiophene, alkyl benzothiophene by LVMS and IR. Their boiling ranges were obtained from the data of ismulated distillation by gas chromatography.
