摘　　要：本文对天津煤气厂的两种焦油（煤焦油和石油焦油）的组成结构进行了研究。首先将焦油简单蒸馏，切取＜２１０℃，２１０～２３０℃，２３０～３００℃和３００～３５８℃四个馏分，然后，应用￣１Ｈ－ＮＭＲ和￣（１３）Ｃ－ＮＭＲ技术分别对各馏分进行分析。结果表明：两种焦油中主要组成化合物有烷基芳烃、萘、甲萘、苊、芴、蒽、菲等。其组成上的显著差异是：煤焦油中含有酚、甲酚及氧芴，而石油焦油中则有苯乙烯和茚。两种焦油中主要成分是萘和菲。The composition and structure of two kinds of tars in Tientsin Gas Works were investigated.First of all,four fractions(<210℃,210～230℃,230 300℃ and 300～358℃)were separated from tar by distillations.Then,All fractions were analysed by￣1H-NMR and￣(13)C-NMR techniques.The results show that chief compounds in the two kinds of tar have:alkyl substituted aromatics,naphthalene,methylnaphthalene,acenaphthene,fluorene,anthracene,phenanthrene et al.Appar ent different in composition is that there are phenol,methylphenol debenzofuran in coal tar while styrene and indene in oil tar.The main component part in the two kinds of tar are naphthalene and phenanthrene.
