【摘要】 以糠醛常压液相加氢反应物经常压精馏生产２甲基呋喃的残液为原料，采用常减压精馏和恒沸精馏，回收残液中剩余的２甲基呋喃、正戊醇和糠醇．３ 种产品的总收率可达６０ ％ ～７０ ％ ．产品质量符合国家标准．副产中间馏分可作溶剂使用．在年处理能力为３００ ｔ 的生产装置上进行工业试验，结果表明：残液回收在技术上可行，且具有较好的经济效益和社会效益．更多还原

【Abstract】 By distilling residue from furfuraldehyle hydrogenation for production of 2\|methyl furan, 2\|methyl furan\,pentanol and furfuryl alcohol can be recovered. The total product yield can achieved 60～70 percent. The product quality comes up to standard. The running results in a industrial unit having production ability of 300 t/a indicated the recovery method was feasible and a good economic and social benefit can be achieved.更多还原
