SF6 Where and How Is SF6 Used?
SF6 is used as an insulating gas in substations, as an insulating and cooling medium in transformers and as an insulating and arc quenching medium in switchgear for high and medium voltage applications. These are all closed systems which are extremely safe and unlikely to leak.
In electrical power systems, high and medium voltage switchgear is required to cut off the power in case of a fault, in order to protect people and equipment. Breakers filled with SF6 are electrically insulating and effectively control arcing.

F6 also is used in other ways. Mixed with argon, it can be used in insulated windows. SF6 is used in the metal industry, for example, when casting magnesium. Eye surgeons use SF6 as a cooling agent in operations. SF6 can also be used as a fire extinguishing agent because it is non-flammable and cooling.
In electrical applications, SF6 is only used in sealed and safe systems which under normal circumstances do not leak gas.
SF6 is collected and recycled if a piece of equipment or a substation needs to be opened.

What Is the Benefit of SF6?
There are two reasons for using SF6 in electrical equipment:
SF6 provides extremely good electrical insulation and very effectively quenches electric arcs. These properties of SF6 make it possible to build electrical equipment and apparatus that are compact, use a small amount of material, are safe and will last a long time. At normal atmospheric pressure, SF6 has a dielectric withstand capability that is 2.5 times better than air. Usually the gas is used at 3-5 times atmospheric pressure and then the dielectric properties are ten times better than for air.
SF6 insulates so well because it is strongly electronegative. This means that the gas molecules catch free electrons and build heavy negative ions, which do not move fast. This is effective against the creation of electron avalanches which may lead to flashovers.
SF6 effectively controls circuit-breaker arcs because it has excellent cooling properties at temperatures (1500-5000 K) at which the arcs extinguish (the gas uses energy when it dissociates and therefore produces a cooling effect).
High-voltage switchgear with SF6 is in principle alone on the market and the volume of medium-voltage switchgear with SF6 is large. Complete gas insulated substations, GIS or RMU, are used where space is restricted or the environment is severe. They are virtually maintenance-free. Electrical equipment filled with SF6 has been in use for about 40 years and the service experience is very good.
SF6 has a very high dielectric withstand capability.
SF6 effectively quenches arcs in circuit breakers.
SF6 apparatus is compact and almost maintenance-free.
SF6 equipment is extremely safe in operation and for users.

Are there Any Alternatives to SF6?
High-voltage circuit breakers filled with SF6 are able to cope with higher unit voltage than any other technique. Therefore, SF6 circuit breakers require fewer breaking units in series than air or oil-filled breakers. SF6 circuit breakers for medium voltage have considerable advantages compared to the alternatives. SF6 substations can be built as totally closed systems which provide the highest levels of operational and user safety.
The designs require only little material; all SF6 apparatus are compact. Compared with electrical apparatus without SF6, the environmental impact is low. Especially if you take into consideration every environmental impact “from the cradle to the grave“, that is, from manufacturing, installation, operation and maintenance all the way to final scrapping (when scrapping equipment , all the SF6 is recovered). So SF6 has many important advantages while currently available alternatives represent a return to older and inferior technology.
Without SF6, we would have a bigger impact on the environment as the alternatives require more space, are less safe and affect the environment more for installers, service personnel and people who live in the area.

IF5,Lodine Pentafluoride is a fluoride of iodine. It is a colourless or yellow liquid with a density of 3250 kg m−3. It was first synthesized by Henri Moissan in 1891 by burning solid iodine in fluorine gas.[2] This exothermic reaction is still used to produce iodine pentafluoride, although the reaction conditions have been improved.[3][4]
I2 + 5 F2 → 2 IF5
Chemistry
Iodine pentafluoride is a strong fluorination agent and is highly oxidative. It reacts vigorously with water forming hydrofluoric acid.
Primary amines react with iodine pentafluoride forming nitriles after hydrolysis with water.[5]
R-CH2-NH2 → R-CN

CAN Code:131307-35-2
Molecular Wt: 331.81
Desc.:Brown Cystalline Powder
Application:
To be used as a fluidizer/fluorinating agent, to make LIVIAL.

N-fluoropyridinium salts have been shown to be stable fluorinating reagents with the ability to fluorinate a variety of organic compounds. For example, T. Umemoto et al., -quot;N-fluoropyridinium Triflate and Its Derivatives: Useful Fluorinating Agents-quot;, Tetrahedron Letters 27(37), 4465 (1986) report that these salts are useful in the fluorination of aromatic compounds and the conversion of enol silyl ethers to alpha-fluoroketones. T. Umemoto et al., -quot;Base-Initiated Reactions of N-fluoropyridinium Salts; A Novel Cyclic Carbene Proposed as a Reactive Species-quot;, Tetrahedron Letters 28(24), 2705 (1987) report that N-fluoropyridinium salts can also be converted in to useful pyridine derivatives such as 2-chloropyridine.

This compound is useful in fluorinating organic compounds including aliphatic compounds such as 1-octyl magnesium bromide and enolate derivatives such as 3-pentanone enol acetate; alicyclic compounds such as 1-morpholino-1-cyclohe-ene, 1-morpholino-1-cyclopentene, 2-carboethoxy cyclopentanone and cyclohexanone trimethyl silyl enol ether; and aromatic compounds such as benzene and anisole.

<p>Sulphur hexafluoride. SF6 is a gas that is used in electrical power equipment. It is colourless, odourless, non-flammable and chemically stable. This means that at room temperature it does not react with any other substance. Stability comes from the symmetrical arrangement of the six fluorine atoms around the central sulphur atom. And this stability is just what makes the gas useful in electric equipment. SF6 is a very good electrical insulator and can effectively extinguish arcs, which makes high and medium voltage apparatus filled with SF6 highly popular. SF6 can be found in millions of electric apparatus all over the world; electrical equipment containing SF6 is a large export article.<br /> <font face="Arial" size="2">SF6 is formed by a chemical reaction between molten sulphur and fluorine. Fluorine is obtained by the electrolysis of hydrofluoric acid (HF).</font><br /> <font face="Arial" size="2">Pure SF6 is not poisonous. The gas is not dangerous to inhale, provided the oxygen content is high enough. In principle you can inhale a mixture of 20% oxygen and 80% SF6 without danger. SF6 is about 6 times heavier than air. That means that it may collect in cable ducts or at the bottom of tanks.
