Xylene - Wikipedia
Xylenes are an important petrochemical produced by alytic reforming and also by coal carbonisation in the manufacture of coke fuel. They also occur in crude oil in concentrations of about 0.5–1%, depending on the source. Small quantities occur in gasoline and aircraft fuels .

- Air Sampling for Oil Mist by the Method NIOSH 5524/cite>
The method was originally developed and still used for the analysis of Metal Working Fluids. Samples are collected on 37 mm PTFE filters or 25 mm IOM samplers. During analysis, mineral oil is selectively extracted from the filter and separated from the dust. Oil is weighed by the laboratory and reported with a sensitivity of 100 μg/sample.

Extraction of the xylylenediamines into toluene proved to be impossible because they are too water soluble. Analysis was thus performed by HPLC using paired-ion chromatography. Adequate sensitivity was obtained using an ultraviolet detector. Ion-pairing is necessary because the polar analytes are not otherwise sufficiently retained.

SKIN Xylene, like other organic solvents, can dissolve the skin’s natural protective oils. Frequent or prolonged skin contact can cause irritation and dermatitis, dryness, flaking and cracking of the skin. Damaged skin may allow greater absorption of chemicals.[11,12] Xylene easily penetrates most ordinary clothing and can become trapped in ordinary gloves and boots.

APPLICABILITY: The working range is 10 to 60 ppm (40 to 200 mg/m 3) for a 3-L air sample. The method is sensitive enough to determine concentrations as low as 12 ppm in 15-min samples taken at 0.2 L/min. NIOSH has sampled for chloroprene at two polychloroprene processing plants. INTERFERENCES: None known.
