The permeation characteristics of eleven petroleum, coal, and shale oil hydrocarbon liquids through eight different types of glove were measured over 24 h. Two analytical techniques, photoionization and room-temperature phosphorescence of polynuclear aromatic compounds, were used to measure breakthrough times by volatile and low-volatility constituents, respectively. The lighter, smaller molecular-size constituents permeated faster than the larger, multi-ringed aromatic constituents. For the light hydrocarbon fuels, especially gasoline, there was preferential permeation by benzene and toluene. Nitrile was severely corroded after extended exposure to hydroxybenzene-containing coal-derived liquids.
