含氮氧自由基和磺酸基共聚物的合成及催化性能
Preparation of copolymers containing nitroxyl radical and sulfonic acid and their catalytic performances
摘要
Abstract
With 2,2'-azobis(2-methylpropionitrile) as the initiator,and sodium p-styrene sulfonate (SSS)and 2,2,6,6-tetramethylpiperidine-4-yl-1-oxyl (TMPM) as the monomers,the copolymer of P(TMPM-co-SSS)was synthesized via free radical copolymerization.Followed by oxidizing it with the mchloroperbenzoic acid,the nitroxyl copolymer of P(TMA-co-SSS)was obtained.Finally acidified by the hydrochloric acid,the bifunctional copolymer of P(TMA-co-HSS)was obtained.Selective catalytic oxidation performances of P(TMA-co-HSS)for benzyl alcohol in a biphasic water-oil NaClO oxidation system were studied.The results showed that the catalytic activity of P(TMA-co-HSS)was good and the yield was up to 89%.Furthermore,the copolymers had excellent recyclability and the activity was not decreased significantly after 3 cycles.The catalytic performance of P (TMA-co-HSS) as a solid acid catalyst for the synthesis of ethyl N-phenylformimidate was also studied.Its catalytic performance was compared with p-toluene sulfonic acid and PHSS.The results showed that the catalytic activity of P(TMA-co-HSS)was excellent and the yield was up to 97%,comparable to p-toluene sulfonic acid.Furthermore,P(TMA-co-HSS) had excellent recyclability and the activity was not decreased significantly after 5 cycles.关键词
