methane - a colorless gas that burns with a blue flame, the main structural component of natural (77-90%) and associated gases, explosive.
produce methane
Said gas is formed as a result of methane, as well as other kinds of fermentation of different organic compounds by bacteria Cellulosae metanicus :
(S6N10O5) nN2O H + - + 3nSN4 3nSO2.
Methane is sometimes called swamp gas, because it is formed by methane fermentation of organic matter on the bottom of natural reservoirs.Furthermore, methane is produced in the intestine and proventriculus ruminant animal feed by fermenting flora.Huge amounts of methane are formed in pathologies - atony proventriculus, toxic dyspepsia, feeding poor quality forages.
Methane is one third of the total weight of proventriculus.When rotting manure of farm animals produce large quantities of methane, which is using special rigs are used for heating of livestock buildings.
produce methane by thermal processing of oil, natural gas, koksirovaniya and hydrogenation of coal (27-38%) provides significant amounts.This gas is the basis of some of the atmosphere of planets (Jupiter, Titan, Saturn).
produce methane at home
to obtain the gas necessary to take some soil from the bottom of the swamp and put it in a jar and then fill with water.Next dish tightly sealed and placed a warm and dark place.After a few days on the water surface, you will notice the appearance of fine bubbles.Gas can be taken away from the banks using flue duct.
methane production in vitro
As a rule, it is synthesized from the reaction of sodium acetate Dumas.To a dry vial make 10 g mixture which consists of one part of sodium acetate and two pieces of soda lime (a saturated solution of sodium hydroxide with calcium oxide in a ratio of 1: 1).The vial was stoppered with a gas discharging tube and fixed to the tripod.Mixture is heated.Note that the first tube is heated, and then - the mixture.Methane, which is formed at this first lowered into the tube with water and then turns into tubes filled with potassium permanganate and iodine with potassium iodide.
Methane is formed by the thermal hydrolysis of sodium acetate with alkali:
sodium acetate, sodium hydroxide + - + methane sodium carbonate
producing ethylene from methane
Ethylene - an important raw material for polystyrene and polyethylene.Modern industrial methods for producing ethylene based upon steam cracking of light oil.A promising alternative to the specified method can be production of ethylene from methane.Unlike oil, natural gas, the main structural component is CH4, considered as the renewable raw materials.In this case the reaction occurs at a temperature of 500-9000 degrees in the presence of O2 and manganese or oxides of cadmium.The resulting gases are separated by absorption deep cooling and distillation under pressure.
In vitro ethylene prepared by methods of dehydration of ethanol and ethane dehydrogenation.The ethylene may be used for the synthesis of ethanol, polyethylene, ethylbenzene, vinyl chloride, antifreeze agents (substances which reduce the freezing point of water in the motor), and other organic compounds.In human and veterinary medicine, ethylene is used as a narcotic drug, in plant breeding - to speed up the ripening of fruits (oranges, lemons, tomatoes, bananas, grapefruits, etc.).
Application methane
Furthermore, methane - a valuable fuel, it also is a raw material for methanol, chloroform, formaldehyde, plastics, etc.Synthesized from methane, acetylene and other compounds.
