Description
Summary:The separation of coal tar into fractions by distillation is studied on periodic laboratory apparatus using columns of different type, with different heating rates of the tar, distillation temperatures, and treatment times. The composition of the light, phenolic, naphthalene, absorbing, and anthracene fractions is determined by chromatography. The results may be used in developing technology for deriving coal tar as a single fraction of specified composition and also for the production of individual compounds that are promising for practical use.
