摘要
总结烷基聚氧乙烯醚 (CmEn)非离子表面活性剂在水溶液中胶团化的焓 /熵补偿行为 ,结果表明CmEn 胶团稳定性随碳氢链长m的增大而增强 ,但随聚氧乙烯链长n增大而下降。补偿温度TC 为 2 7℃±2℃。
The enthalpy-entropy compensation behavior of micellization of C mE n nonionic surfactants in aqueous solutions has been concluded by the data of the critical micelle concentration(cmc)in literature.The result showed that the stability of the structure of micelles is enhanced as increasing the hydrocarbon chain length,however,it is weakened as increasing PEO chain length.The compensation temperature T c was found to be 27 ℃± 2 ℃ .
