- 1,4-Dioxane, often
called dioxane because the 1,2 and 1,3 isomers of dioxane are rare,
is a heterocyclic organic compound.
- It is a colorless
liquid with a faint sweet odor similar
to that of diethyl ether. It is classified as an ether.
- It is a volatile
organic compound that has a moderate vapor pressure and has a
specific gravity of 1.033. It is very mobile and only weakly
retarded by sorption during transport.
- This colorless liquid
is mainly used as a stabilizer for the solvent trichloroethane. It
occasionally used solvent for a variety of practical applications as
well as in the
- Dioxane is produced by
the acid-catalyzed dehydration of Diethylene glycol, which in turn
arises from the hydrolysis of ethylene oxide.
- Dioxane is primarily
used as a stabilizer for 1,1,1-trichloroethane for storage and
transport in aluminium containers.
- 1,4-Dioxane is a
cyclic ether, and is also known as p-dioxane, diethylene ether,
diethylene dioxide and glycol ethylene ether. This compound is
highly soluble in water, owing to its molecular structure.
- It is flammable and is
available in reagent technical ( more than 99.9% pure),
spectrophotometric and scintillation grades.
- It is used in various
manufacturing process and is included in a variety of consumer and
- Dioxane is used as a
reaction medium solvent in organic chemical manufacture, as a
wetting agent and dispersing agent in textile processing, as a liquid
counting medium, as a reagent for laboratory research and testing,
in the preparation of histological sections for microscopic
examination and in stain and printing compositions.
- Uses include paper
manufacturing solvent), paint and varnish remover, deodorants,
shampoos , soaps and cosmetics, in furnigants and pesticides, in
in pharmaceuticals as a purifying agent, and as an antifreeze
- The concentration of
1,4-Dioxane is measure by relating the MS response of the
quantitation ion to the response of the deuterated surrogate
standard quantitation ion.
- 1,4 dioxane is also
produced as a by-product during the manufacture of polyester.
- It is a recalcitrant
molecule to biodegrade under conventional biotreatment
- 1,4-Dioxane is an EPA
priority pollutant often found in contaminated ground waters and
- The common
techniques used for water purification are not applicable to
1,4-dioxane and the currently used method (distillation) is
laborious and expensive.
- It is a byproduct of
the hydrolysis of ethylene oxide and can be found in approximately
46% of all personal care products like lotions, shampoos and liquid
- Testing for
1,4-Dioxane at low levels can be problematic due to its affinity for
water, decreasing its volatility and purge efficiency by traditional
purge and trap methods.
characteristics of 1,4-dioxane such as high mobility, enable it to
migrate much further than the solvent from which it likely
- A catalyzed conversion
of diethylene glycol to 1,4-dioxane undertaken over zeolites,
ZSM-5,ZSM-48 and Zeolites beta is characterized by high selectivity.
- Dioxane is an
important industrial solvent for cellulose esters and ether, and
other oils and resins. It can be produced from the less valuable
reactant, diethylene glycol.
polyethylene glycol to 1,4-dioxane using a solid cation exchange
resin as the dehydration catalyst.
- A Process for
destroying dioxane in a water vapor stream includes combusting the
stream to decompose dioxane contained therein.
- The process is
particularly useful for removal of dioxane from byproducts streams
which result during the production of polyester.
- A bromine chloride
complex of p-dioxane has been discovered which is useful as a solid
source of bromine chloride.
- A dioxane-bromine
chloride complex formed by mixing bromine chloride with dioxane in
methylene chloride at 10C. has been used to selectively brominate
