罗一平主持了乔治W.胡贝尔问：你有没有用不同比例的水和溶剂进行实验？为什么选择80：20的比例？另外，关于木质素的回收，在130 ℃下的实验中，木质素的结构是否与原始木质素的结构不同？乔治胡贝尔回答说：对于LGO生产，我们已经使用不同比例的水和溶剂进行了实验，如我们最近发表的绿色化学论文中所述。1使用主要含有THF和1- 2.5wt%H2O的溶剂，1，6-己二醇前体的总产率最高。在极性非质子溶剂中，所需反应的反应速率要高得多，这就是我们选择此比例的原因。此外，使用这些溶剂，需要低得多的酸浓度。
Yiping Luo opened the discussion of the paper by George W. Huber by asking: Did you carry out experiments using different ratios of water and solvent? Why did you choose the ratio 80: 20? Also, regarding recovery of the lignin, a er the experiment at 130 C, is the structure of the lignin different to that of the original lignin?George Huber responded: For LGO production, we have done experiments using different ratios of water and solvent as described in our recently published Green Chemistry paper. 1 The overall yield of 1, 6-hexanediol precursors was highest using a solvent containing primarily THF with 1–2.5 wt% H2O. The reaction rates for the desired reactions are a lot higher in polar aprotic solvents so that is why we choose this ratio. Also, with these solvents, a much lower concentration of acid is required.
