[求助]
求助漢翻英。歡迎指正錯誤。。高分子材料方面
|
|||
|
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(yīng)2小時，得到的QHEC取代度最優(yōu)為0.61，反應(yīng)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(yīng)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.

更正下，有個地方錯了~，呵呵，下面是對的~ HEC, etherification agent and alkali were added in to the reaction with the amounts of 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%. |

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） |
