In the manufacture of gasoline from crude oil, ethyl tert-butyl ether (ETBE) is widely used as an oxygenate gasoline additive. ETBE provides similar or greater air quality benefits than ethanol while requiring less technological and logistical effort. ETBE, unlike ethanol, does not allow fuel to evaporate, which is one of the causes of smog, and it does not absorb moisture from the air.
The acidic etherification of isobutylene with ethanol at a temperature of 30–110 °C and a pressure of 0,8–1,3 MPa is used to make ethyl tert-butyl ether in industry. As a catalyst, an acidic ion-exchange resin is used in the reaction. [two]
The following is not an appropriate reaction for the preparation
As gasoline is made from crude oil, tert-Butyl ethyl ether is used as an oxygenate gasoline additive. By using single-walled carbon nanotubes as an adsorbent, it is used as an extractant in human urine. It contributes to the octane rating of gasoline by acting as a fuel component.

Methyl tert-butyl ether production (mtbe) (lec098)
The need for cleaner-burning fuel has been facilitated by the air pollution crisis and new environmental regulations. Oxygenate additives, which can boost octane and promote full fuel combustion, are becoming increasingly relevant in the creation of a greener and more sustainable world. In this brief analysis, one of the more well-known oxygenate additives, ethyl tert-butyl ether (ETBE), is discussed; this compound gained popularity after the drawbacks and negative effects of methyl tert-butyl ether (MTBE) were discovered. The topic focuses on ETBE production patterns as well as the evolution of traditional separation techniques toward hybrid processes. Furthermore, a novel idea is suggested and discussed that includes the use of nanomaterials (carbon nanotubes (CNTs) and graphenes) in the processing and separation of ETBE.
