Dusts also have upper and lower explosion limits, though the upper limits are hard to measure and of little practical importance. Lower flammability limits for many organic materials are in the range of 10–50 g/m 3, which is much higher than the limits set for health reasons, as is the case for the LEL of many gases and vapours. Dust clouds ...
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.
Xylene is among the 30 most produced chemicals in the country. It is described as a colorless, ... Ether is a group of flammable and explosive gaseous and liquid chemicals, according to the ...
Its explosive limits range from 1.9% to 10.0%, with a vapor density of 2.5 and a specific gravity of 0.8. This colorless, flammable liquid, bearing an acetone-like odor and miscibility in alcohol and ether, finds primary use as a solvent in nitrocellulose coatings and lacquers, paint removers, adhesives, cements, and in printed circuit board ...
m-Xylene (meta-xylene) is an aromatic hydrocarbon. It is one of the three isomers of dimethylbenzene known collectively as xylenes . The m- stands for meta- , indicating that the two methyl groups in m -xylene occupy positions 1 and 3 on a benzene ring.
