摘要：对异构十三醇聚氧乙烯醚上的环氧乙烷数(EO数)及用3个环氧丙烷数(3PO数)对其封端后的构效关系进行了对比性研究。对不同的异构十三醇聚氧乙烯醚及3PO封端的异构十三醇聚氧乙烯聚氧丙烯醚的表面张力、临界胶束浓度、润湿性质、泡沫性质、乳化力及浊点进行了测试,发现随着EO数的增加异构十三醇聚氧乙烯醚的最低表面张力(γcmc)、临界胶束浓度(cmc)、稳泡力、起泡力、润湿时间及浊点均增大。PO封端后,相较于封端前,其表面张力增大;临界胶束浓度、稳泡力、起泡力、乳化力及浊点均降低;EO数大于9时,封端后的润湿力相较于封端之前有所提高。最终结果表明聚醚的不同结构对其性能有不同的影响。
The structure-property relationship of iso-tridecanol polyoxyethylene ether with different number of ethylene oxide(EO)units was studied,as well as their performance after blocking with 3 units of propylene oxide(3PO).The surface tension,critical micelle concentration(cmc),wetting properties,foam properties,emulsifying power and cloud point of iso-tridecanol polyoxyethylene ethers and 3PO-blocked iso-tridecanol polyoxyethylene polyoxypropylene ether were investigated.The results show that the minimum surface tension(γcmc),the cmc,the foam stability and the foaming power,the wetting time and the cloud point of iso-tridecanol polyoxyethylene ether are increased with the increase of the EO number.It is also found that when PO is blocked,its surface tension is increased;the cmc,foam stability,foaming and emulsifying ability and cloud point are decreased;when the EO number is greater than 9,the wetting force is increased.In summary,the structure of polyethers affects their properties.
