- The term xylene refers to a group of
three benzene derivatives which are used as a solvent and in the
printing, rubber, and leather industries. Xylene is a colorless,
sweet-smelling liquid that is very flammable.
- The 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.
- Xylenes are flammable liquids and
fire hazards. When heated to decomposition, xylenes emit acrid smoke and
fumes.
- The effect of H2 on isomerization
pathways and on the acid site density onWOx-ZrO2 catalysts was explored
using kinetic measurements of acid-catalyzed o-xylene isomerization
reactions.
- The Badger/Niro Para-xylene
Crystallization process recovers high-purity para-xylene from aromatic
streams.
- Peroxide and formaldehyde
modifications are presented in improved indophenol-xylene extraction
method which minimize the interference due to reduced tin and iron,
sulfite, and reductones.
- Xylene is used as a solvent, to
manufacture gasoline, as a raw material for the production of organic
chemicals used to make polyester fibers, and to make dyes and
insecticides.
- p-Xylene, the most important
commercial isomer, is primarily converted for use in fibers, films, or
resins, including polyester fibers which are used for household fabrics,
carpets, and clothing.
- Xylene has been used as a
polymerization solvent for acrylic resins and as a reflux solvent in the
manufacturing alkyd and polyester resins.
- Xylene has been traditionally used as
a clearing agent in tissue processing for many years, primarily because
it is miscible with both alcohol and wax while doing an excellent job of
clearing the tissue of alcohol.
- The isomeric concentrations of meta,
ortho, and para xylene are important to quantify for the production of
many polymer compounds. Raman spectroscopy technique presents the
fastest and easiest method of making this determination.
- PVA-fixed fecal material which was
previously examined by the standard technique and found to contain the
protozoans indicated below was selected to evaluate Hemo-De as a xylene
substitute in the trichrome staining technique.
- Due to its downstream demand, the
para-xylene market is robust and generally sees steady year-on-year
demand growth in the range of 6-8% per year.
- Worldwide para-xylene production
capacity exceeded the demand by more than 4.5 million metric tons per
annum (MMTA), lowering the average capacity utilization to less than
80%.
- All producers have captive supplies
of mixed xylenes. Large quantities of unisolated o-xylene in mixed
xylene streams are used in gasoline or isomerized to p-xylene.
