Quantitative test of the PEG1000-DAIL leaking was carried out by distillation in vacuum after decantation of upper layer and extraction with diethyl ether for three times to ensure complete removal of impurities. Compared with the traditional solvents and catalysts, the easy recycling performance and only 7.5% leakage of catalyst over ten runs make PEG1000-DAIL attrac-tive.  发自小木虫IOS客户端 |

PEG1000-DAIL泄漏的定量试验在真空中通过蒸馏进行，即上层倾析后用乙醚萃取三次以确保完全除去杂质。与传统的溶剂和催化剂相比，PEG1000-DAIL具有便于回收的特性，而且经过10次以上的运行过程后催化剂泄漏只有7.5％，使其具有吸引力。 |

Compared with the traditional solvents and catalysts, the easy recycling performance and only 7.5% leakage of catalyst over ten runs make PEG1000-DAIL attractive. 上层液体移去后用乙醚沉淀三次去除杂质之后, PEG1000-DAIL的损失用真空蒸馏方法定量测定。与传统的溶剂和催化剂相比，可再生性和催化剂在使用十次后只损失7.5%使PEG-DAIL非常诱人。 Leaking, 可能是指催化活性部分从配位基团上掉了下来，这里译成损失。 |
