中文摘要：

用傅立叶变换红外光谱考察了水介质液化煤反应前后产物的变化，以1HNMR和GC—MS为手段考察了不同反应温度下液化产物结构组成的变化．实验结果表明，不同反应温度对产物组成变化存在影响，且在液化油中发现有酚类物质．用重水交换实验证实了产物中确实有酚类存在，对煤液化工艺条件的优化具有一定的指导意义．

英文摘要：

The diversification of hydroliquefaction production after reaction were analyzed by FTIR. The change of structure and component with different reaction temperature were surveyed by 1HNMR and GC-MS. We could concluded that the production component is varied by reaction temperature and hydroxybenzene is found in oil. The existence of hydroxybenzene in the hydroliquefaction production is proved by 1HNMR spectra which added D2O into the sample solution. All above is very meaningful to hydroliqueFraction craft.
