摘要： Methyl tertiary butyl ether is prepared from contaminated TBA by reactively distilling the contaminated TBA in a reactive distillation column to provide a lower boiling isobutylene fraction and a higher boiling aqueous TBA fraction, by distilling the higher boiling aqueous TBA fraction to provide a lower boiling TBA fraction, by charging the lower boiling isobutylene fraction, the lower boiling tertiary butyl alcohol fraction 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.

摘要： A tertiary butyl alcohol charge stock contaminated with from about 0.5 to about 2 wt. % of corrosive oxygen-containing impurities, including peroxides and formates, is passed through an oxygenates decomposition reactor containing a bed of a basic zeolite catalyst to decompose the peroxides and oxygen-containing impurities, including peroxides and formates, and to dehydrate a portion of the tertiary butyl alcohol to form isobutylene and water to form a substantially less-corrosive tertiary butyl alcohol feedstock that is substantially free from oxygen-containing impurities, including formates that is suitable for reaction with methanol in a methyl tertiary butyl ether etherification reactor to form a methyl tertiary butyl ether etherification reaction product from which methyl tertiary butyl ether can be recovered.
