| Abstract | 以实验室自制的杨木木屑液化油为原料,经过水分离与离心分离后得到水溶性和水不溶性杨木木屑液化油,利用石油醚等多种极性不同的有机溶剂对两种液化油进行分级萃取,同时考察不同种类双水相体系的分相能力；利用FT-IR分析样品中所含物质官能团的变化。结果表明：水溶性液化油中乙酸乙酯的萃取率最高可达22.50%,而水不溶性液化油中氯仿的相对萃取率最高可达13.50%,磷酸氢二钠与乙醇构成的双水相体系萃取率最高,使液化油中水含量降低71.80%,达到较好的改性效果。FT-IR分析结果表明：杨木木屑液化原油经过水分离后,大部分杂质及易老化的物质被除去,可提高杨木木屑液化油的纯度和利用率。 |
| Other Abstract | Using wood liquefaction oil of laboratory self-made as raw material, wood liquefaction oil of water soluble and water insoluble was obtained after water separation; the factional extraction on two kinds of wood liquefaction oil by different solvent was used for the studying of the occurrence modes after water, while studying different kinds of aqueous two-phase system ability to split phase. The results showed that the highest extraction rate is achieved 22.50% by ethyl acetate in the water soluble wood liquefaction oil, and in the water insoluble wood liquefaction, the highest relative extraction rate is achieved 13.50% by chloroform, the highest extraction rate of double water phase system which is composed of disodium hydrogen phosphate and ethanol can reach 71.80%, this achieved a good modification effect. FT-IR analysis results showed that the most components of wood liquefaction oil after water separation is reduced and most of the impurities and easy aging material are removed, these improve the purity and utilized ratio of wood chips liquefaction oil. |
