Method for etherifications
Abstract
A method is described for producing tertiary ethers from C[sub 4] or C[sub 5] streams containing isobutene and isoamylene respectively in a process wherein a acidic cation exchange resin is used as the catalyst and as a distillation structure in a distillation reactor column, wherein the improvement is the operation of the catalytic distillation in two zones at different pressures, the first zone containing the catalyst packing and operated a higher pressure in the range of 100 to 200 psig in the case of C[sub 4] and 15 to 100 psig in the case of C[sub 5] which favors the etherification reaction and the second zone being a distillation operated at a lower pressure in the range of 0 to 100 psig in the case of C[sub 4] and 0 to 15 psig in the case of C[sub 5] wherein a first overhead from the first zone is fractionated to remove a portion of the unreacted alcohol from the first overhead and to return a condensed portion containing said alcohol to the first zone and to produce a second overhead having less alcohol than said first overhead. 3 figs.
