| Abstract: | Extraction of products into dichloromethane solution from reactions of Victorian brown coals with hydrogen in tetralin can be achieved in 2 min by immersing the extraction mixture in an ultrasonic bath at ambient temperature. The same levels of extraction using the Soxhlet technique can only be achieved by prolonged periods of extraction during which the coal extracts are heated at the reflux temperature of the solvent. |
