Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Butane shopping experience:
1. Compare - without doubt the biggest advantage that the Butane offers shoppers today is the ability to compare thousands of Butane at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.
2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about
3. Testimonials - don't know anybody that has bought a Butane? Wrong! If the Butane is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.
4. Questions - Got a question about Butane then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....
5. Reputation - Never heard of the company selling Butane? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Butane and build up a picture of their reputation for sales, returns, customer service, delivery etc.
6. Returns - still worried that even after all of the above your Butane wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.
7. Feedback - happy with your Butane then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.
8. Security - check for the yellow padlock on the Butane site before you buy, and the s after http:/ /i.e. https:// = a secure site
9. Contact - got a question about Butane, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.
10. Payment - ready to pay for your Butane, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

Butane, also called
n-butane', is the unbranched alkane with four carbon atoms, CH3CH2CH2CH3. Butane is also used as a collective term for n-butane together with its only other isomer, isobutane (also called methylpropane), CH(CH3)3.Butanes are highly flammable, colorless, easily liquefy gases. The name butane was derived by back-formation from the name of
butyric acid.
Image:Butane-2D-Skeletal.svg|n-ButaneImage:I-Butane-2D-Skeletal.svg|i-Butane
Reactions and uses
When oxygen is plentiful, butane burns to form carbon dioxide and water vapor; when oxygen is limited, carbon (soot) or carbon monoxide may also be formed.
2C4H10 + 13O2 → 8CO2 + 10H2O
n-Butane is the feedstock for
DuPont's catalytic process for the preparation of maleic anhydride:
CH3CH2CH2CH3 + 3.5O2 → C2H2(CO)2O + 4H2O
n-Butane, like all hydrocarbons, undergoes free radical chlorination providing both 1-chloro- and 2-chlorobutanes, as well as more highly chlorinated derivatives. The relative rates of the chlorination is partially explained by the differing bond dissociation energies, 425 and 411 joule/mol for the two types of C-H bonds. The two central carbon atoms have the slightly weaker C-H bonds. band emission and Swan bands.
Butane gas is sold bottled as a fuel for cooking and camping. When blended with Propane and other hydrocarbons, it is referred to commercially as
Liquified petroleum gas. It is also used as a petrol component, as a feedstock for the production of base petrochemicals in steam cracking, as fuel for
cigarette lighters and as a propellant in aerosol sprays.
Very pure forms of butane, especially isobutane, can be used as
Liquified petroleum gas#LPG as refrigerant and have largely replaced the ozone layer depleting halomethanes, for instance in household refrigerators and freezers. The flammability of butane is not a major issue because the amount of butane in an appliance is not enough to cause a combustible mix given the amount of air in a room. The system operating pressure for butane is lower than for the halomethanes, such as
Dichlorodifluoromethane, so direct conversion of R-12 systems to butane, such as in automotive air conditioning systems, will not function optimally.
Effects and health issues
Inhaling butane can cause drowsiness, narcosis, asphyxia; cardiac arrhythmia and frostbite, which can result in instant death from
Asphyxiation,
Acute toxicity and ventricular fibrillation. Butane is the most commonly misused volatile solvent in the UK, and was the cause of 52% of solvent related deaths in 2000.
