Ethyl tert-butyl ether

Ethyl tert-butyl ether (ETBE) is commonly used as an oxygenate gasoline additive in the production of gasoline from crude oil. ETBE offers equal or greater air quality benefits than ethanol, while being technically and logistically less challenging. Unlike ethanol, ETBE does not induce evaporation of gasoline, which is one of the causes of smog, and does not absorb moisture from the atmosphere.

Synthesis

It is synthesized by mixing ethanol and isobutylene and reacting them with heat over a catalyst.

Ethanol, produced by fermentation and distillation, is more expensive than methanol, which is derived from natural gas. Therefore, MTBE, made from methanol is cheaper than ETBE, made from ethanol.

    Feel Too Good

    by: Utopia

    Feel too good to go to work today
    I need a little more time so I can stay this way
    Let's go for a ride on the circle line
    Couldn't you use a day in the sunshine
    Mustn't let your bank payments get behind
    The bills may pile up, I just brush them off my mind
    I can't let debt collectors bother me
    Because I feel too good
    I feel so good that you just can't bring me down
    I can't remember when I felt so high
    My mind is on vacation and I don't know why
    Wouldn't you like to go for a country drive
    Doesn't it make you feel good to be alive
    Luncheon by the roadside will do just fine
    I left the water running
    It just must have slipped my mind
    Can't let the little things bother me
    Because I feel too good
    I feel so good that you just can't bring me down
    Someone's bound to bring you down
    There's a strange speaking man on the front lawn
    Making rude noises and gestures
    It's just the neighbor's got something on his mind
    Feel too good
    I can't let frenchie start to bother me
    Because I feel too good
