Studies on the Composition and Aging of Marine Tars.
Abstract
Experimental aging of Arctic diesel, gasoline, motor oil, benzene, and petroleum ether in marine simulated environment failed to produce any tar-like material. Bunker C produced tars quickly. Southern Louisiana crude oil failed to form tars even when asphalt was added to the solution before aging. Presumably some combination of surface energy and mutual solubilities prevents tar formation in this case. The effect warrants further investigation. Aging experiments seem to show that asphaltenes form from other components during aging. Analyses of marine tars demonstrate the value of separating tar components and analyzing the fractions separately. Presence of particulate iron in some marine tars strongly supports the hypothesis that man's activities are involved in their formation. Attached fouling organisms appear to be an important agent in removing floating tar from the sea surface.
