Excerpt from Coal Tar Distillation: And Working Up of Tar Products When considering the low temperature tars the fact that they contain parafiinoid bodies should not be overlooked. Coalite tar is a member of the class of tars containing these bodies. This tar varies in specific gravity between and it contains practically no free carbon or naphthalene, and the first products of distillation are very volatile. It is these distillates which contain the paraffin bodies, and from the tar distiller's point of view render the tar valueless. It should find use as a fuel oil, or if sufficient volume can be obtained to warrant separate storage and distillation, the lighter distillates could be employed, after rectification, for motor spirit and the heavier distillates for fuel oil. Table VII gives the results of two analyses of coalite tar. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
