Shenfu Coal was extracted with hot pure water and slurry was isolated. The concentrated benzene-soluble fraction (CBSF) was analyzed with GC/MS and four types of organic compounds (OCs) were detected: HACOCs, DTEs, DMDT and LCAs. The amount of benzyl benzoate which is the most abundant OC was calculated by an internal standard method with an indicated amount of BP. The broken hydrogen bonds and ether bonds were responsible for the extraction of OCs from the coal .DTEs, DMDT and LCAs are essentially insoluble in water, whereas they are soluble, probably owing to intermolecular interaction of OCs with HACOCs.
