摘要：

A novel commercial process has been successfully developed to separate indole, methylnaphthalene and tar bases such as quinoline and isoquinoline contained in wash oil which is produced by the distillation of coal tar. The process consists of tar-base removal, indole removal, using an oligomerization technique, and purification of the desired products. The indole oligomerization method is the most efficient and economic technology ever commercialized for separating indole of low content from other components contained in tar-base-removed wash oil. Construction of a plant was completed at Mizushima Works in May 1988, and the plant has been smoothly operated to produce purified indole, methylnaphthalene, quinoline and isoquinoline.
