Production Of Liquid Hydrocarbon Mixture For Refining Petroleum

Abstract
The separation of the constitutents of mixtures such as crude resorcinol, crude anthracene cake, crude anthraquinone, &c., is effected by distilling the substance with a mineral oil, such as kerosine, fuel oil, &c., containing fractions which boil within wide limits. The constituents of the mixture distil over with the oil at different stages and are collected separately. Alternatively, a mineral oil fraction having a boiling point above that of any of the constituents of the mixture to be separated, is used. The mixture is heated and, at various stages in the rise of temperature, steam is passed through the mixture to carry off the constituents separately in the order of their volatility. In treating crude anthracene cake, carbazole passes over first, then anthracene and finally phenanthrene.
