FOERFARANDE FOER FRAMSTAELLNING AV TERT. BUTYLALKYLETRAR I NAERVARO AV BUTADIEN

摘要

In producing t-butyl alkyl ethers by etherifying with aliphatic alcohols isobutene in a hydrocarbon feedstock containing butadiene in addition to the isobutene, the increase in the pressure drop in the etherification reactor(s) that is due to the butadiene is eliminated by feeding the reactants from the bottom upwards. The reactors preferably contain an acidic ion-exchange resin catalyst.
