Uses: In addition to being directly used as fuel and refrigerant, this product is widely used to prepare a variety of organic synthetic raw materials, such as butene and butadiene can be produced by dehydrogenation; isobutane can be produced by isomerization; Catalytic oxidation can produce maleic anhydride, acetic acid, etc.; halogenation can produce halobutane; nitration can produce nitrobutane; catalysis can produce carbon disulfide at high temperature; hydrogen can be produced by steam reforming. In addition, butane can also be used as a motor fuel blend to control volatile content; it can also be used as a deasphalting agent for refining heavy oil; a solvent for wax precipitation in oil wells; an overflow agent for secondary oil recovery; a resin foaming agent; Fresh water refrigerant, and olefin Ziegler polymerization solvent, etc.
Reaction and use: Alkanes are inert gases because their C-C and C-H bonds are very strong. They do not react with acids, alkalis, metals or oxidants. Surprisingly, they do not react with acids or bases. But gasoline (octane) does not react with concentrated sulfuric acid, alkali metals or potassium permanganate. It burns to form carbon dioxide and water vapor
Butane + oxygen-
Carbon dioxide + water vapor
2 C4H10 + 9 O2 -
8 CO2(g) + 10 H2O
If there is sufficient air supply, carbon dioxide and water vapor will be produced when butane burns. If the air supply is insufficient, carbon and carbon monoxide will be produced. The daily uses of butane include domestic liquefied petroleum gas, and it is also used as fuel in lighters and portable butane gas stoves.
Freon and chlorofluorocarbons can cause ozone layer depletion, causing concern. Therefore, refrigeration systems, especially household refrigerators and refrigerators, have increased the use of isobutane (2-methylpropane) as a refrigerant instead of Freon. In addition, isobutane is also added to sprays to replace chlorofluorocarbons.
