| 摘 要： | 以对氟苯酚和3-溴丙烯为原料,无水乙醇为溶剂,经O-烷化、克莱森重排和硅氢加成得到了有机磷毒剂敏感材料聚甲基[3-(2-羟基-5-氟)苯基]丙基硅氧烷.研究了各因素对各步反应的影响,得到的较佳工艺条件为将对氟苯酚和溴丙烯于55℃回流4 h得到中间产物对氟烯丙基苯基醚(Ⅰ),接着将Ⅰ在200℃ 保温7 h得到2-烯丙基_4-氟苯酚(Ⅱ),然后将Ⅱ和含氢硅油在100℃反应4 h.利用FT-IR和1HNMR对各级反应产物结构进行了表征.将聚甲基[3-(2-羟基-5-氟)苯基]丙基硅氧烷料涂覆在QCM传感器上研究了其对有机磷毒剂模拟剂DMMP的响应特性.结果表明传感器响应迅速,对干扰气体、水和乙醇的响应低于含有苯酚官能团的聚合材料.

| Abstract: | Poly{methyl[3-(2-hydroxy-5-fluoro)phenyl] propyl siloxane}, sensitive to the poisonous organophos- phate vapor,was synthesized through O -alkylation,Claisen rearrangement reaction and hydrosilylation reaction. And that these reactions were prepared with 4-fluoro phenol and allyl bromide as materials in anhydrous ethanol. After analyzing the factors in each reaction,better conditions for technology were obtained:when synthesizing 4-flu- oro allyl phenyl ether (I),4-fluoro phenol and allyl bromide were reflux... |
