Abstract

A process for the treatment of coal tar comprising thoroughly mixing the coal tar with a surface-active composition chosen from the class of compounds having the general formula CH3 (CH2)X CH2 (OCH2CH2)Y OSO3<->, M<+> in which X ranges from 6,5 to 13 and Y is at least 1,5, followed by a separation of water and quinoline insoluble components from the mixture, and a method of eliminating or minimizing the build-up of coal tar derived deposits on surfaces in contact with the coal tar.
