用氧化还原法分离柴油中的硫化物。详细考察了氧化剂TBAPI和MCPBA的氧化条件及硅胶柱分离条件 ,并选择还原剂LiAlH4对各自的氧化物进行了还原。对分离所得硫化物的基本结构和类型进行了红外和质谱鉴定 ,结果表明 :柴油中硫醚硫主要是环戊硫醚类硫化物 ,噻吩硫主要是烷基噻吩、苯并噻吩、二苯并噻吩及其同系物
Sulfur compounds in diesel oil are separated by redox method. The oxidation conditions of TBAPI and MCPBA oxidant and the separation conditions of silica gel column were investigated in detail, and the respective oxides were reduced with LiAlH4 as reductant. The basic structure and type of the isolated sulfide were identified by IR and MS. The results showed that: the thioether sulfur in diesel oil is mainly sulfur pentasulfide, thiophene sulfur is mainly alkylthiophene, benzothiophene, dibenzo Thiophene and its homologues
