| 摘 要： | 用场解吸质谱（ＦＤＭＳ）对乙烯渣油中间相沥青（ＥＴＭＰ）和澄清油中间相沥青（ＤＯＭＰ）之甲苯可溶组分（ＴＳ）的组成结构进行了对比研究。通过对两种中间相沥青ＴＳ组分质谱峰的合理归属，鉴定出了主要的组成化合物系列以及各自相对应化合物的结构，分析极限大大扩大，在ＤＯＭＰ－ＴＳ中检测到的最高质量数为９９０，相应于１６个芳环的稠环芳烃分子；在ＥＴＭＰ－ＴＳ中检测到的最高质量数为９４８。相应于１５个缩合芳环的稠环芳烃分子，ＤＯＭＰ－ＴＳ含较多的迫位缩合芳环而ＥＴＭＰ－ＴＳ含较多的渺位缩合芳环，同时对中间相沥青的组成结构与其物理化学性能作了关联。

| Abstract: | The molecular distributions and constitutions of toluene soluble (TS)in decant oil mesophase pitch(DOMP)and ethylene tar residue mesophase pitch (ETMP) were studied using field desorption mass spectrometry (FDMS). The molecular profiles of all samples analyzed were greatly extended and the maximum mass weight of DOMP-TS was 990 corresponding 16 aromatic condensed rings, while that of ETMP-TS was 948 representing 15 kata condensed rings. DOMP-TS contains more of peri condensed aromatic rings, while ETMP-TS containing more of kata-condensed aromatic rings. The physicochemical properties of the two kinds mesophase pitches were related to the compound species and molecular distributions. |
