摘　　要：以棉织物为载体,含有季铵盐阳离子、交联基团、长链烷基的丙烯酸酯共聚物为改性剂,通过浸轧整理制备相转移催化织物,并将其应用于Williamson醚合成反应。研究了整理温度、时间、磷酸用量、负载量和改性剂中烷基长链结构对催化活性的影响,分析了相转移催化织物的适用性与回用性。结果表明:当焙烘温度为170℃,焙烘时间为1.5 h,12%的磷酸乙醇溶液用量为0.60 g,负载量为20%,十八酯为改性剂中烷基时,催化织物的催化活性最佳。此外,催化织物具有较高的适用性与稳定性,在应用于多种苯酚衍生物的Williamson醚合成反应时转化率均可达到92%以上,且在回用5次后,催化活性无明显变化。该研究可为相转移催化剂的固定化研究提供新的思路。Phase transfer catalytic cotton fabric was prepared with the pad finishing method with cotton fabric as the carrier and acrylic copolymer with quaternary ammonium cation,crosslinking group and long chain alkyl as the modifier.It was also applied in Williamson ether synthesis.The effect of the finishing temperature,finishing time,the amount of phosphoric acid,loading amount,and the structure of the long chain alkyl of the modifier on the catalytic activity of the catalytic fabric was studied.The applicability and reuse performance of the phase transfer catalytic fabric were analyzed.It was found that the catalytic fabric exhibited the excellent catalytic activity if baking was carried out at the temperature of 170℃for 1.5 h with 0.60 g of 12%phosphoric acid,the loading amount of 20%and octadecyl as the long chain alkyl of the modifier.Moreover,the catalytic fabric also showed high applicability and stability.The conversion rate for Williamson ether synthesis reaction of several other phenol derivatives could also reach 92%.The catalytic fabric showed little change in catalytic activity even after being reused for 5 times.The research could provide new ideas for the investigation for the immobilization of phase transfer catalyst.
