摘　　要：以酰氯为酰基化试剂,用三乙胺作缚酸剂和催化剂,制备了一系列对叔丁基杯[8]芳烃酯类衍生物(2a～2e),其结构经1H NMR,IR和元素分析表征。以2为萃取剂,考察了酯型儿茶素单体在二氯甲烷-水两相体系中的萃取分配行为。结果表明:2e的萃取效果最佳。A series of t-butylcalix [ 8 ] arene ester derivatives （2a - 2e） were synthesized using acyl chlorides as acetylating reagents, using triethylamine as a catalyst and an acid binding agent. The structures were characterized by ^1 H NMR, IR and elemental analysis. Distribution behaviors of ester catechins monomers were investigated using 2 as an extractant in two-phase system of dichloromethane-water. The experimental results showed that 2e was the best extractant
