History of Distillation - ScienceDirect

A comprehensive book on coal tar distillation was written by Georg Lunge in 1867 . Lunge was born in 1839 in Breslau (Wroclaw), and he studied chemistry there and in Heidelberg. From 1864 to 1876 he worked in England, starting as chemist in a coal tar distillery, and then progressing to manager of a large soda factory in the Tyne district.

Destructive distillation of coal leads to the formation of:

Distillation normally removes over 99.9 percent of the dissolved materials, regardless of their effects on water quality. Dissolved minerals impart flavor to water. Because distillation removes minerals, distilled water is often flat and tasteless.

Coal Tar - an overview | ScienceDirect Topics

Coal tar is a complex hydrocarbon mixture produced by thermal destruction (pyrolysis) of coal, typically a dark viscous liquid or semisolid with a smoky or naphthenic odor. The composition of coal tar will be influenced by the process used for pyrolytic distillation as well as by the original composition of the coal; however, all coal tars will ...
