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.
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.

Negative photoresists are composed of a poly(cis-isoprene) matrix, xylene solvent, and bis-arylazide as the photoactive compound. Negative photoresists react to light by polymerizing. The unexposed portions can be removed by using a developer solution. negative resist has better adhesion and is great for features greater than 2 μm in size.

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 ...
Principally, paints are either a colloidal suspension of solid pigment particles or are an emulsion of dense viscous dye gel or paste with a filler all dispersed through a lighter free-flowing liquid medium — the solvent. This solvent also controls flow and application properties, and in some cases can affect the stability of the paint while ...
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.
