Method of producing tertiary amyl ethyl ether |
| abstract |
A process for the production of tertiary ethers, including: feeding a hydrocarbon stream comprising isoolefins and propionitrile to a distillation column reactor system containing at least one etherification reaction zone; feeding a C 2 to C 6 monoalcohol or mixture thereof to the distillation column reactor; concurrently in the distillation column reactor system: reacting a portion of the isoolefins with a portion of the alcohols to form a tertiary ether; and separating the tertiary ether from unreacted isoolefins; withdrawing the tertiary ether and propionitrile from the distillation column reactor system as a bottoms; withdrawing the unreacted isoolefins from the distillation column reactor system as an overheads; and operating the distillation column reactor system such that the etherification reaction zone is substantially free of propionitrile. |
