Coals of three different ranks have been extracted by four different solvents, namely, pyridine, quinoline, tetralin and tetrahydroquinoline while being irradiated with ultrasonic energy in the 60 kHz range. The effect of initial particle size, coal rank and time of irradiation has been investigated. The effect of temperature on the highest yield systems for a particular coal has also been studied at 30°, 45° and 65°C.
