英文摘要	运用傅立叶变换红外光谱研究了钾皂化2－乙基已基磷酸单2－乙基巴基酯（简称HEHPEHE或P507）的性质，同时配合激光光散射技术研究皂化应对形成微乳液性能的影响．红外光谱的研究表明，皂化度（αs）超过60％时，（K，H）EHPEHE呈现酸盐体系的特殊性质，体系对水的增溶能力迅速增大，该体系开始具有形成微乳液的能力；αs为75％左右时，体系对水的增溶能力最强；大于75％时，随着皂化度的继续增加，体系对水的加溶能力迅速下降．激光光散射的实验结果表明，αs为75％时，微乳体系中的平均液滴半径达到最大值（103.8nm）。红外光谱的结果证明形成微乳液对HEHPEHE分子中的P－O－C、P＝O和P－O－...; The properties of potassium saponified 2-ethylhexyl phosphoric acid mono-2-ethylhexyl ester (HEHPEHE or P507) as well as the formation of microemulsions (water/(K,H)EHPEHE/n-heptane) have been investigated by means of Fourier Transform Infrared Spectroscopy(FT-In). The stretching; bands of P-O-H and the P-O-C shift with the saponification due to the interaction of HEHPEHE and the saponified resultant (KEHPEHE), named acid-salt system. The absorbance of P-O-H stretching vibration varies to lower frequencies while P-O-C stretching band shifts to higher wavenumbers with the increases of saponification. Furthermore, the P-O-C stretching band splitted into two distinct peaks after the saponification exceeds 60%. Water/(K,H)EHPEHE/n-heptane microemulsions could be formed when the saponification was higher than 60%. The water solubility and the average diameter of droplets in microemulsion reach their maxims at the saponification of 75%.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000076166300006&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科学引文数据库(CSCD); 1; 09; 794-798; 14
