Why is ethane an important industrial chemical?
Like propane and, to a lesser extent, butane, ethane is a major raw material for the huge ethylene petrochemical industry, which produces such important products as polyethylene plastic, ethylene glycol, and ethyl alcohol.
Why is ethene an important hydrocarbon?
Ethylene is also an important natural plant hormone and is used in agriculture to force the ripening of fruits….Ethylene.

What can ethene be used for?
Uses of Ethene (ethylene)
| Production of Polythene (polyethylene) | nCH2=CH2 |
|---|---|
| Production of chloroethane chloroethane is used to manufacture tetraethyl lead tetraethyl lead is the lead additive in leaded petrol | CH2=CH2 + HCl |
| Ethene is also used as a plant hormone to control the ripening and colour development of fruit |
Why is ethene and steam an important industrial reaction?
Ethanol is manufactured by reacting ethene with steam. The reaction is reversible, and the formation of the ethanol is exothermic. By removing the ethanol from the equilibrium mixture and recycling the ethene, it is possible to achieve an overall 95\% conversion.
Why is ethene described as a feedstock for making industrial substances?
A feedstock is a raw material used to provide reactants for an industrial reaction. A petrochemical is a substance made from crude oil using chemical reactions. For example, ethene is produced from crude oil. It is used as feedstock to make poly(ethene), a polymer .
Why is the chemical industry important for the nation?
Nepal has to be transformed from a commodity based economy to a manufacturing based economy. Resource based chemical industry plays an important role in revitalising and sustaining the long-term growth of economy. Thus chemical industry development in Nepal is very crucial.
Which of the following substances is used to produce ethene in petrochemical industry?
It is the building block for a vast range of chemicals from plastics to antifreeze solutions and solvents. Figure 1 On the site at Grangemouth in Scotland, ethene is produced by steam cracking of naphtha….Annual production of ethene (ethylene)
| World | 134 million tonnes1 |
|---|---|
| Middle East | 20 million tonnes1 |
What are the chemical properties of ethane?
Ethane appears as a colorless odorless gas. It is easily ignited. The vapors are heavier than air.
How is ethene used commercially?
Ethene is used routinely within the food industry to provide controlled ripening during storage and transport or when fruit is displayed in shops, in sealed packages. Bananas are picked when they are green and unripened. Ethene is a hydrocarbon gas and it speeds up ripening in bananas and other fruit.
What are the advantages of using ethene to prepare ethanol?
There are many advantages to making ethanol from ethene (a hydrocarbon obtained from crude oil). It is a fairly cheap process and it is continuous, which means that more can be made for a smaller price in a smaller time. There aren’t any waste products, whereas in the process of fermentation carbon dioxide is released.
What is ethene made of?
Ethene (ethylene) is the most important organic chemical, by tonnage, that is manufactured. It is the building block for a vast range of chemicals from plastics to antifreeze solutions and solvents. Figure 1 On the site at Grangemouth in Scotland, ethene is produced by steam cracking of naphtha.
What are the uses of ethethylene?
Ethylene is used to make three important chemicals, viz., ethylene oxide, ethylene dichloride and ethylbenzene, which are precursors to the manufacture of many commonly used materials. The main use of ethylene oxide is to make ethylene glycol used for anti-freeze for car cooling systems. Other glycol ethers and acetates are widely used as solvents.
What is the industrial importance of ethane?
The industrial importance of ethane is based upon the ease with which it may be converted to ethylene (C2H4) and hydrogen by pyrolysis, or cracking, when passed through hot tubes. Ethane gas can be liquefied under pressure or at reduced temperatures and thus be separated from natural gas.
What is the use of ethene in everyday life?
Ethene is used in making polyethylene. Ethene is converted to ethanol which is used as a starting material in cosmetics and toilet preparations. Ethene is used for ripening of fruits. Ethene is used for making oxyethylene lamp which is used for cutting and welding of metals.
