Abstract
This substance, which has been discovered by Reichenbach amongst the products of destructive distillation of wood, has been repeatedly the subject of chemical investigation, but owing to the difficulty attending its purification, the chemical nature of creosote remained doubtful until 1858, when Hlasiwetz published his elaborate research on this subject. Up to that time Reichenbach’s creosote was frequently confounded with phenol (phenylic alcohol, carbolic acid); and, indeed, the latter had very nearly supplanted the true creosote in its application. Hlasiwetz first prepared the creosote in a chemically pure state, and ascertained its chemical formula to be C 8 H 10 O 2 , and showed that this substance, although having some characteristic properties in common with phenol, was a distinct chemical substance, and otherwise in no way related to this body.
