| titleOfInvention | Process for preparation of ethers in a catalytic distillation column |
| abstract | A process for preparing ethers includes the steps of:nproviding a feedstock containing iso-olefins selected fromnthe group consisting of C5 iso-olefins, C6 iso-olefins andnmixtures thereof; mixing the feedstock with alkyl alcohol sonas to provide a reaction feedstock, feeding the reactionnfeedstock to a reactor zone in the presence of a firstnetherification catalyst whereby the alkyl alcohol reactsnwith the iso-olefins to form alkyl-tert-alkyl ethers so asnto provide an intermediate feedstock containing the ethersnand unreacted iso-olefins and alkyl alcohol; feeding thenintermediate feedstock to a catalytic distillation columnnhaving a second etherification catalyst defining a catalyticnzone; mixing additional alkyl alcohol to the intermediatenfeedstock so as to form azeotropes of the alkyl alcohol withnthe unreacted iso-olefins without forming azeotropes of thenalkyl alcohol with the ethers whereby the catalytic zone isnsubstantially free of the ethers and the unreacted iso-olefinsnreact with said alkyl alcohol in the catalytic zonento form additional alkyl-tert-alkyl ethers. |
