It is well known that hydroaromatics, possessing hydrogen-donating ability, effectively act in extractive chemical disintegration and hydrocracking of coals. On the other hand, hydrocracked coal liquids produced by use of zinc chloride catalyst could be expected to be suitable solvents in these reactions because they were confirmed to be rich in hydroaromatics. So, in the present study, coal liquid products were prepared by hydrocracking of Akabira and Taiheiyo coals with the catalyst, and properties and powers in extractive chemical disintegration of their fractions at 230-270°C, 270-340°C and above 270°C were investigated in comparison with those of tetralin and anthracene oil: it was found that solubility of coals in these fractions was far more than that in anthracene oil and comparable to or more than that in tetralin. But as fractions above 270°C contain components to be easily carbonized, their usage should be limited to a narrow range of reaction conditions.
