; ;
A simplified method has been developed for the extractive separation of coal tar or pitch, to make various pitches with specified properties. The yield of coal tar or pitch of any given quality depends on how rich the feedstock is in fractions soluble in toluene or insoluble in quinoline. The extractive treatment of medium pitch produces a special pitch, the composition and properties of which can be varied by using different amounts of different solvents. 5 tables.
