HC Refrigerant Gas C4H10 On Sale for Refrigerator,Air Conditioner
C4H10,Isobutane (i-butane), also known as methylpropane, is an
isomer of butane. It is the simplest alkane with a tertiary carbon.
Concerns with depletion of the ozone layer by freon gases have led
to increased use of isobutane as a gas for refrigeration systems,
especially in domestic refrigerators and freezers, and as a
propellant in aerosol sprays. When used as a refrigerant or a
propellant, isobutane is also known as R-600a. Some portable camp
stoves use a mixture of isobutane with propane, usually 80:20.
Isobutane is used as a feedstock in the petrochemical industry, for
example in the synthesis of isooctane.
C4H10,Isobutane is used as a refrigerant.The use in refrigerators
started in 1993 when Greenpeace presented the Greenfreeze project
with the German company Foron. In this regard, blends of pure, dry
"isobutane" (R-600a) (that is, isobutane mixtures) have negligible
ozone depletion potential and very low Global Warming Potential
(having a value of 3.3 times the GWP of carbon dioxide) and can
serve as a functional replacement for R-12, R-22, R-134a, and other
chlorofluorocarbon or hydrofluorocarbon refrigerants in
conventional stationary refrigeration and air conditioning systems.
In the Chevron Phillips slurry process for making high-density
polyethylene, isobutane is used as a diluent. As the slurried
polyethylene is removed, isobutane is "flashed" off, and condensed,
and recycled back into the loop reactor for this purpose.
Isobutane is also used as a propellant for aerosol cans and foam

As a refrigerant, isobutane has an explosion risk in addition to
the hazards associated with non-flammable CFC refrigerants. Reports
surfaced in late 2009 suggesting the use of isobutane as a
refrigerant in domestic refrigerators was potentially dangerous.
Several refrigerator explosions reported in the United Kingdom are
suspected to have been caused as a result of isobutane leaking into
the refrigerator cabinet and being ignited by sparks in the
electrical system.Although unclear how serious this could be, at
the time this report came out it was estimated 300 million
refrigerators worldwide use isobutane as a refrigerant.
Substitution of this refrigerant for motor vehicle air conditioning
systems not originally designed for R600a is widely prohibited or
discouraged, on the grounds that using flammable hydrocarbons in
systems originally designed to carry non-flammable refrigerant
presents a significant risk of fire or explosion.
Vendors and advocates of hydrocarbon refrigerants argue against
such bans on the grounds that there have been very few such
incidents relative to the number of vehicle air conditioning
systems filled with hydrocarbons.
