A hydrocarbon isolated from a fraction of a Kuwait mineral oil has been identified by synthesis as 1,2,7,8-tetramethylfluorene. A crystalline mixture of methylbenzo[a]fluorenes from an Oklahoma oil is shown by gas chromatography to contain at least six components, four of which have retention times coincident with those of the 1-, 3-, 4-, and 10-methyl isomers. Syntheses of 1-, 3-, and 4-methylbenzo[a]fluorene
从科威特矿物油的一部分中分离出的烃已通过合成鉴定为1,2,7,8-四甲基芴。气相色谱显示,来自俄克拉荷马州油的甲基苯并[ a ]芴的结晶混合物包含至少六个组分,其中四个的保留时间与1-,3-,4-和10-甲基异构体的保留时间一致。描述了1-,3-和4-甲基苯并[ a ]芴的合成。
