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. 發(fā)自小木蟲IOS客戶端 |

PEG1000-DAIL泄漏的定量試驗(yàn)在真空中通過蒸餾進(jìn)行，即上層傾析后用乙醚萃取三次以確保完全除去雜質(zhì)。與傳統(tǒng)的溶劑和催化劑相比，PEG1000-DAIL具有便于回收的特性，而且經(jīng)過10次以上的運(yùn)行過程后催化劑泄漏只有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. 上層液體移去后用乙醚沉淀三次去除雜質(zhì)之后, PEG1000-DAIL的損失用真空蒸餾方法定量測(cè)定。與傳統(tǒng)的溶劑和催化劑相比，可再生性和催化劑在使用十次后只損失7.5%使PEG-DAIL非常誘人。 Leaking, 可能是指催化活性部分從配位基團(tuán)上掉了下來，這里譯成損失。 |
