Preparation:
Most of the methods for extracting Chinolin are chemical method or salt solution extraction method. First, chinolin and other alkaline substances in the wash oil are separated and extracted to obtain crude chinolin, and then rectified by atmospheric or reduced pressure to obtain industrial chinolin . The chemical method is a more economical and reasonable method, but there are many process steps, mainly including acid washing, benzene washing, alkaline washing, water washing and vacuum distillation. For pickling, sulfuric acid is used.
