Ing Of Dodecane To Make Ethene Cracked To Produce

Crude oil is first separated into fractions by fractional distillation.

The heavier fractions can be split up into smaller molecules by catalytic cracking.

Ing Of Dodecane To Make Ethene Cracked To Produce

One molecule of decane can be cracked to produce one molecule of ethene and.

In organic chemistry, an alkene is an unsaturated hydrocarbon that contains at least one carboncarbon double bond.

Chemical Equations.

C10H22- 2C5H11 (radicals).

C5H11 (radical) - C3H7 (radical) C2H4.

C3H7 (radical) - C6H14.

Fractions that are produced by the distillation distillation: Distillation is when we make a liquid evaporate and then condense the vapour back to a purer liquid.

This chemical reaction produces smaller hydrocarbons, including alkanes and alkenes.

Ethene and other alkenes are unsaturated unsaturated: An unsaturated compound contains at least one double or triple bond.

Cracking Fuels made from oil mixtures containing large hydrocarbon hydrocarbons: Hydrocarbons are a group of compounds which contain the elements hydrogen and carbon.

Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules.

This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules.

Like cycloalkanes, alkenes have the general formula C n H 2n.

Hydrocarbons that contain one or more triple bonds are called alkynes, and is the name ending is yne.

Heating ethane with steam is an important commercial process for making ethene (or ethylene).

This is an important commercial process called steam cracking.

The double bonds become completely conjugated and no longer behave as double bonds.

The removal of a hydrogen atom from a hydrocarbon molecule leaves an alkyl group that readily attaches to a functional group, or forms a branch on a hydrocarbon chain.

For example, CH 3 is named methyl; CH 3 CH 2, ethyl; CH 2 CH, ethenyl; CH 3 CH 2 CH 2, propyl; and so on.

A benzene ring from which a hydrogen atom has been removed is often referred to as a phenyl.

The branched molecules shown here would be given names as follows.

Theoretically there is no limit to the length of hydrocarbon chains.
