Coal Tar - an overview ScienceDirect Topics

Coal tar pitch is defined as the residue (nonvolatile at 450°C) from the distillation of coal tars produced by the high temperature pyrolysis (>1000°C) of coal. 40 The molecular structure of coal tar pitches usually consists of an aromatic core with only a few methyl groups attached. In that sense, coal tar pitch is more aromatic and has a smaller degree of substitution than does
