中文摘要：
以邻二氯苯、1-溴己烷和1-溴辛烷为起始原料经过偶联得到邻二烷基苯,再与顺丁烯二酸酐经Friedel-Crafts酰基化反应,合成了两种不饱和羧酸——4-（3,4-二正己基苯基）-4-氧代-2-丁烯酸和4-（3,4-二正辛基苯基）-4-氧代-2-丁烯酸,总收率分别为59%和42%,经过核磁共振谱、红外光谱和高分辨质谱对产物结构进行了确认。然后用氢氧化钠中和得到两种不饱和羧酸钠盐,并测量了它们不同浓度的表面张力。
英文摘要：
4-（ 3,4-Dihexylphenyl） -4-oxobut-2-enoic acid and 4-（ 3,4-dioctylphenyl ） -4-oxobut-2-enoic acid were synthesized via coupling reaction of o-dichlorobenzene and 1-bromohexane /1-bromooctane and the subsequent Friedel-Crafts acylation with maleic anhydride in overall yields 59% and 42% , respectively. The structures of 4-（ 3,4-dihexylphenyl ） -4oxobut-2-enoic acid and 4-（ 3,4-dioctylphenyl ） -4-oxobut-2enoic acid were confirmed by NMR,IR and HRMS. After neutralization with sodium hydroxide,Furthermore,the interfacial tensions of sodium salts of compounds were measured.
