摘　　要：以一种褐煤和一种煤焦油为原料,在高压釜中进行加氢反应,正己烷萃取液相产物,碱抽提法富集萃取物中的酚类化合物并进行GC/MS分析.结果表明,在褐煤液化油体系中共鉴定出24种酚类化合物,在煤焦油加氢体系总共鉴定出21种酚类化合物,煤基油中酚类化合物包含苯酚、茚满酚和萘满酚,高级酚含量居多.煤基油中多数酚类化合物含有烷基侧链,3及3以上碳数的侧链构成多样复杂.A lignite and a coal tar is hydrogenated to oil in autoclave respectively. The liquid in autoclave is extracted by hexane. Phenolic compounds in extract are enriched by alkali extraction and analyzed by GC/MS. The results show that 24 phenolic compounds are identified in lignite liquefaction oil and 21 phenolic compounds in coal tar hydrogenation oil. Phenolic compounds in coal-derived oil are phenols, indanols and naphthalenols among which high rank phenols have the most amount. Most phenolic compounds of coal-derived oil are alkyl substituted with side chain＇s diversity and complication of 3 or over 3 carbons.
