1,2,7,8- and 1,3,6,8-Tetramethylcarbazole have been isolated from a fraction of a Kuwait mineral oil and identified by comparison with synthetic specimens obtained by photocyclisation of tetramethyldiphenylamines. A pentamethylcarbazole was also isolated, and was not identical with synthetic 1,2,3,5,7-pentamethylcarbazole.
从一部分科威特矿物油中分离出1,2,7,8-和1,3,6,8-四甲基咔唑,并通过与通过光环化四甲基二苯胺获得的合成标本进行比较来鉴定。还分离出五甲基咔唑,与合成的1,2,3,5,7-五甲基咔唑并不相同。
