What is the principal use made of oxygenates such as methyl tert-butyl ether, MTBE, in the petrochemicals industry?
Worked Solution & Example Answer:What is the principal use made of oxygenates such as methyl tert-butyl ether, MTBE, in the petrochemicals industry? - Leaving Cert Chemistry - Question b - 2007
Step 1
Raise octane number / Prevent auto-ignition (pre-ignition, knocking, pinging)
Answer
One of the primary uses of methyl tert-butyl ether (MTBE) in the petrochemical industry is to raise the octane number of gasoline. A higher octane number improves fuel performance by preventing auto-ignition, which in turn avoids issues such as pre-ignition, knocking, and pinging in engines.
Step 2
Step 3
Less pollution / Less carbon monoxide (CO) produced
Answer
Additionally, MTBE contributes to reduced pollution overall, particularly in the production of carbon monoxide (CO). By utilizing MTBE, the emission of CO during fuel combustion is significantly lowered, which is beneficial for environmental protection and public health.
