The first paper is the recent study by Andrews and colleagues performed in Zambia.
Related compounds Xylenols - types of phenols Infobox disclaimer and references Xylenes form azeotropes with water and a variety of alcohols.
The demand for isophthalic acid is relatively modest so m-xylene is rarely sought and hence the utility of its conversion to the o- and p-isomers. Solvent applications and industrial purposes[ edit ] Xylene is used as a solvent.
In this application, with a mixture of isomers, it is often referred to as xylenes or xylol. Solvent xylene often contains a small percentage of ethylbenzene.
Like the individual isomers, the mixture is colorless, sweet-smelling, and highly flammable. Areas of application include the printingrubberand leather industries.
It is a common component of ink, rubberand adhesives. In dentistry, xylene can be used to dissolve gutta perchaa material used for endodontics root canal treatments. In the petroleum industry, xylene is also a frequent component of paraffin solvents, used when the tubing becomes clogged with paraffin wax.
For similar reasons, it is often the active ingredient in commercial products for ear wax cerumen removal. After staining, microscope slides are put in xylene prior to mounting with a coverslip.
Precursor to other compounds[ edit ] Although conversion to terephthalic acid is the dominant chemical conversion, xylenes are precursors to other chemical compounds.
For instance chlorination of both methyl groups gives the corresponding xylene dichlorides bis chloromethyl benzenes whilst mono-bromination yields xylyl bromidea tear gas agent used in World War I.
Long-term exposure may lead to headaches, irritability, depression, insomnia, agitation, extreme tiredness, tremors, hearing loss, impaired concentration and short-term memory. There is very little information available that isolates xylene from other solvent exposures in the examination of these effects.
The use of impervious gloves and masks, along with respirators where appropriate, is recommended to avoid occupational health issues from xylene exposure.XCOM UOP Essentials Of Managerial Communication,XCOM UOP Entire Course, XCOM Complete Course Assignment, XCOM Full Class Compile the documents for the Business Writing Portfolio in Appendix A.
