Dehydrocyclisation Flashcards
What does dehydrocyclisation involve?
It involves the use of catalysts to form ring compounds
What happens when dehydrocyclisation occurs?
Straight-chain alkanes are converted to cycloalkanes which are then converted to aromatic compounds
Why are ring aromatic compounds useful?
They have a high-octane rating
Describe the dehydrocyclisation process of hexane.
Hexane is converted into cyclohexane +H2 which is then converted into benzene +3H2
What alkane can be converted into benzene through dehydrocyclisation?
Hexane
What is hexane first converted into during dehydrocyclisation?
It is converted into cyclohexane + H2
What is cyclohexane +H2 converted into during the dehydrocyclisation of hexane?
It is converted into benzene + 3H2
Other than high-octane compounds, what is produced through dehydrocyclisation?
Hydrogen is produced
What is done to the hydrogen produced as a result of dehydrocyclisation?
It is a valuable product and is therefore piped away to be used for various purposes
Explain ‘dehydrocyclisation’
2
Hydrogen is being removed
A cyclic compound is formed (ring formation)
