Methyl Tertiary Butyl Ether (MTBE) is an organic compound used extensively in the petrochemical industry, primarily as a fuel additive to improve the quality and performance of gasoline. Methyl Tertiary Butyl Ether (MTBE) is produced through a process called etherification, which involves the reaction of isobutylene (C₄H₈) with methanol (CH₃OH) in the presence of an acid catalyst, typically sulfuric acid or an ion-exchange resin. The reaction takes place in a reactor under controlled temperatures and pressures, producing MTBE and water. After the reaction, the product mixture undergoes distillation to separate MTBE from unreacted isobutylene and methanol. The purified MTBE is then stored and transported for use primarily as a gasoline additive, where it enhances combustion efficiency and increases octane ratings. This process effectively transforms light hydrocarbons into a valuable fuel component
