高分子材料方面求指正改正。。。。 對于HEC,在HEC用量為5g、醚化劑用量為7.5g、堿用量1.85g、在65℃下反應2小時,得到的QHEC取代度最優(yōu)為0.61,反應效率為64%;對于PVA,在PVA的濃度為5%、醚化劑用量為7g、堿用量2.5g、在65℃下反應6小時,得到的QPVA取代度最優(yōu)為3.95。 For HEC, the HEC dosage of 5g, etherification agent is 7.5g, alkali 1.85g, at 65 ℃ for 2 hours, the optimal degree of substitution obtained QHEC 0.61, the reaction efficiency was 64%; for the PVA, the PVA concentration of 5%, etherification agent is 7g, alkali 2.5g, at 65 ℃ for 6 hours, get QPVA optimal degree of substitution 3.95.

前兩句我認為不恰當?shù)牡胤揭呀浉牧藒。呵呵。就是貼上去的。 第三局和第四局實在是看著有點分不著頭腦。 “對于HEC,在HEC用量為5g、醚化劑用量為7.5g、堿用量1.85g、在65℃下反應2小時,得到的QHEC取代度最優(yōu)為0.61,反應效率為64%;改為: HEC, etherification agent and alkali were added in to the reaction with the amounts of which were 5g, 7.5g and 1.85g respectively. The reaction will last 2 hours at the temperature of 65 ℃, and the optimal degree of substitution will be up to 0.61 with the reaction efficiency of 64%. 下一句你應該可以了吧~,也許我寫的也不多,相互交流吧~,O(∩_∩)O~ |

PVA and HEC are water-soluble. We used 3-chloro-2-hydroxypropyl trimethyl ammonium chloride as etherifying agent to introduce quaternary ammonium groups into the structure of PVA and HEC through quaternization reaction to prouduce quaternized QPVA and QHEC, respectively. The effect of reaction conditions on the degree of substitution and reaction efficiency were studied. For HEC, the HEC dosage of 5g, etherification agent is 7.5g, alkali 1.85g, at 65 ℃ for 2 hours, the optimal degree of substitution obtained QHEC 0.61, the reaction efficiency was 64%.(這句話沒有謂語)好好改改~ for the PVA, the PVA concentration of 5%, etherification agent is 7g, alkali 2.5g, at 65 ℃ for 6 hours, get QPVA optimal degree of substitution 3.95. (同上) |
