| 1 | 正、负离子碳氟-碳氢表面活性剂混合水溶液的表面活性显示文摘Surface Activities of aqueous mixtures of cationic anionic fluorocarbon hydrocarbon surfactants, F[CF(CF 3)CF 2O] 2CF(CF 3)CONH(CH 2) 3N(C 2H 5) 2CH 3I/C nH 2n+1 COONa (n=7,9,11,13) and F[CF(CF 3)CF 2O] 2CF(CF 3)COONa/C nH 2n+1 N(CH 3) 3Br(n=8,10,12),were investigated.It was showed that,counter charged hydrocarbon surfactants increase the efficiency and in some cases the effect of fluorocarbon surfactants was to decrease surface tension of aqueous solution.However,surface activity of fluorocarbon surfactants is decreased if the length of hydrocarbon chains is longer than that of fluorocarbon chains. | 肖进新 罗妙宣 胡昌明 Teodor Dehelean | 2000 | 化学研究与应用2000，12，3： | 21 |

| 10 | POLYMER-SUPPORTED SINGLE AND MIXED AMMONIUM AND PHOSPHONIUM SALTS AS CATALYSTS FOR PHASE-TRANSFER REACTIONS显示文摘In this study was to investigate, by phase-transfer catalysis, the activity of single and mixed ammonium and phosphonium salts grafted on a 揼el-type?styrene-7% divinylbenzene copolymer in the oxidation of benzyl alcohol with hydrogen peroxide. A wide variety of catalysts with different quaternary groups and different quaternary chain length substituents were examined. The activity of single 搊nium?salts increases as a consequence of the association of ammonium and phosphonium salts grafted on the same polymeric support. The activity of polymer-supported ammonium and phosphonium salts increases with the number of carbon atoms contained in the alkyl radicals of the onium and of the functionalization degree with phosphonium groups. | POPA Adriana PARVULESCU Viorica ILIESCU Smaranda ILIA Gheorghe DEHELEAN Gheorghe | 2001 | Chinese Journal of Reactive Polymers2001，10，2： | 0 |
