ABSTRACT:
Methyl tertiary butyl ether is prepared from TBA contaminated with oxygen-containing impurities by decomposing the impurities to gaseous products, by charging the thus-treated tertiary butyl alcohol and methanol to an etherification reactor to form an etherification reaction product, by distilling the etherification reaction product to provide a lower boiling fraction containing isobutylene, methanol and methyl tertiary butyl ether by charging the lower boiling fraction to a finishing reactor to react the isobutylene and methanol contained therein to from additional MTBE and by recovering MTBE from the etherification reaction product and the isobutylene conversion product.
