Xylene is used in the laboratory to make baths with dry ice to cool reaction vessels, [17] and as a solvent to remove synthetic immersion oil from the microscope objective in light microscopy. [18] In histology, xylene is the most widely used clearing agent. [19] Xylene is used to remove paraffin from dried microscope slides prior to staining.
Hippuric acid has long been used as an indicator of toluene exposure; [14] however, there appears to be some doubt about its validity. [15] There is significant endogenous hippuric acid production by humans; which shows inter- and intra-individual variation influenced by factors such as diet, medical treatment, alcohol consumption, etc. [15] This suggests that hippuric acid may be an ...
Breathing in xylene is the most common form of exposure. Small amounts of xylene vapors can cause headaches, dizziness, drowsiness and nausea, according to the ATSDR. Vapors can also irritate the ...
o-Xylene (ortho-xylene) is an aromatic hydrocarbon with the formula C 6 H 4 (CH 3) 2, with two methyl substituents bonded to adjacent carbon atoms of a benzene ring (the ortho configuration). It is a constitutional isomer of m-xylene and p-xylene, the mixture being called xylene or xylenes. o-Xylene is a colourless slightly oily flammable ...
Paint markers, and permanent markers generally, contain the toxic compounds xylene or toluene. Like spray paint, these markers give off volatile organic compounds, which can be dangerous when used in a badly ventilated area or without a particulate mask. Gloves can also be worn to avoid absorption through the skin.
Solvent exposure is common among men and women working in industrial settings. Specific solvents including xylene, perchloroethylene, toluene and methylene chloride have been shown to be associated with a concurrent elevation in risk for spontaneous abortion [35]
Likewise, the para-xylene consumption showed unprecedented growth in 2010, growing by 2,800,000 tons, a full ten percent growth from 2009. [1] Toluene is also a valuable petrochemical for use as a solvent and intermediate in chemical manufacturing processes and as a high octane gasoline component. [2] [3] [4] [5]
Aromatics like benzene, toluene or xylene may also be used. [6] The hydrocarbons used are sometimes made by hydrogenation from naphtha. The lipophilic liquids dissolve fat-soluble lubricants or oils. Some products also contain polar solvents such as ethanol, [7] methanol, [8] isopropanol, and acetone in order to dissolve non-lipophilic ...
