The enantiomeric resolution and the elution order of (+/-)-trans-7,8-dihydrodiols of benzo[a]pyrene and its 6-fluoro and 6-bromo derivatives were analyzed on three polysaccharide-based columns: Daicel Chiralcel CA-I (cellulose triacetate), OF, and OG [cellulose tris(4-chloro- and 4-methylphenylcarbamate)]. For comparison, the separation of (+/-)-1,1'-bi-2-naphthol was evaluated on the OG and OF columns
在三种基于多糖的色谱柱上分析了苯并[a] py的(+/-)-反式-7,8-二氢二醇及其6-氟和6-溴衍生物的对映体拆分度和洗脱顺序。 I(纤维素三乙酸酯),OF和OG [纤维素三(4-氯-和4-甲基苯基氨基甲酸酯)]。为了进行比较,在OG和OF色谱柱上评估了(+/-)-1,1'-bi-2-萘酚的分离度。(6-)-7,8-二羟基-7,8-二氢苯并[a] py的(S)-1,1'-bi-2-萘酚和(7S,8S)-异构体与手性吸附剂的相互作用可能相似建议。
