Condensate waters from the Bureau of Mines synthane process for coal gasification have been investigated by mass spectrometric methods to determine the organic contaminants. Waters from the gasification of six coals were extracted with methylene chloride, yielding 0.6 To 2.4 Weight-percent extractable material. Using high-resolution mass spectrometry (hrms), combined gas chromatography-mass spectrometry (gc-ms), and low-voltage mass psectrometry, 60 to 80 percent of the extract was found to be phenolic. About 20 organic contaminants have been identified and are present in the condensate waters from each coal gasified. The relative distribution of contaminants in the consensate water was nearly the same for the six coals gasified under various conditions; phenolic compounds were the most abundant in all cases.
