用(+)-TAPA固定的氧化铝柱,用高效液相色谱法可分离dl-顺式和dl-反式烯烃。7顺式异构体得到部分拆分(t/-(+)-II:[a] 225?8+ 88 c 1.60 X 10-3,正己烷)。此外,反式异构体可完全拆分(/-)。
Both dl-cis and dl-trans olefins could be resolvedusing HPLC techniques by employing an alumina column impreg-nated with (+)-TAPA. 7 Partial resolution of the cis isomer was achieved (t/-(+)-II:[a] 225? 8+ 88 c 1.60 X 10-3,«-hexane). In addition thetrans isomer could be resolved completely (/-
