The three xylene isomers: o-xylene, m-xylene, and p-xylene In organic chemistry, xylene or xylol (from Greek ξύλον (xylon) ' wood '; [1] [2] IUPAC name: dimethylbenzene) are any of three organic compounds with the formula (CH 3) 2 C 6 H 4.They are derived from the substitution of two hydrogen atoms with methyl groups in a benzene ring; which hydrogens are substituted determines which of ...

Commercial or mixed xylene usually contains about 40-65% m-xylene and up to 20% each of o-xylene and p-xylene and ethylbenzene. Xylenes are released into the atmosphere as fugitive emissions from industrial sources, from auto exhaust, …

Effect of xylene on the central nervous system is attributed to the liposolubility of xylene in the neuronal membrane. It has been suggested that xylene disturbs the action of proteins essential to normal neuronal function either by disruption of the lipid environment in which the membrane proteins function or by direct interaction with the proteins in the membranes.[]

In this report, the terms xylene, xylenes, and total xylenes will be used interchangeably. There are three forms of xylene in which the methyl groups vary on the benzene ring: meta-xylene, ortho-xylene, and para-xylene (m-, o-, and p-xylene). These different forms are referred to as isomers. The term total xylenes refers to all three isomers of xylene (m-, o-, and p-xylene).

xylene, any of three isomeric dimethylbenzenes [which have the same chemical formula, C 6 H 4 (CH 3) 2, but different molecular structure], used as solvents, as components of aviation fuel, and as raw materials for the manufacture of dyes, fibres, and films.The three isomers, designated ortho (o), meta (m), and para (p), differ structurally only in the location of the methyl groups.

p-Xylene (para-xylene) is an aromatic hydrocarbon.It is one of the three isomers of dimethylbenzene known collectively as xylenes.The p-stands for para-, indicating that the two methyl groups in p-xylene occupy the diametrically opposite substituent positions 1 and 4.It is in the positions of the two methyl groups, their arene substitution pattern, that it …

Xyleen is een ontvlambare vloeistof. Inademing van de dampen kan aanleiding geven tot hoofdpijn, duizeligheid, misselijkheid of bewusteloosheid. De stof is irriterend voor de huid en de ogen. Blootstelling van zwangere vrouwen aan xyleen dient vermeden te worden.

Jul 17, 2024 · Paint and coatings: Many paint manufacturers use xylene as a thinner in paints and primers, and it's a common ingredient in enamels and varnishes. It's also present in many paint solvents because it can easily dissolve paints, resins, pigments, and adhesives. Cleaning agents: Xylene is popular in cleaning solutions due to its ability to remove grease and other stains.

There are three forms of xylene in which the methyl groups vary on the benzene ring: meta-xylene, ortho-xylene, and para-xylene (m-, o-, and p-xylene). These different forms are referred to as isomers. Xylene is a colorless, sweet-smelling liquid that catches on fire easily. It occurs naturally in petroleum and coal tar. Chemical industries produce xylene from petroleum.

Apr 11, 2023 · Xylene, also known as Xylol or dimethylbenzene, is an organic compound widely used in the solvent, medical, and technology industries. It is specifically classified as an aromatic hydrocarbon and is a colorless solvent with a sweet, gas-like smell and a greasy texture.
