High-Resolution Mass-Spectrometric Investigation of Coal Derivatives
The Pittsburgh Coal Research Center of the Federal Bureau of Mines is attempting to determine which specific organic structures contribute desirable properties to commercially important fractions of coal tars such as road tar and electrode binder pitch. The current emphasis is on a survey of the types of hydrocarbon structures in coal extracts, tars, and related samples detectable by high-resolution mass spectrometry. Mass-spectral data have also been obtained for several altered coals and coal derivatives, including weathered road tar.
