Process for obtaining isobutene from mixtures of C4-hydrocarbons containing isobutene |
| abstract |
The present invention relates to a process for the recovery of isobutene from isobutene-containing C4 hydrocarbon mixtures by reacting the mixture with a primary alcohol in the presence of an acidic condensing agent to form the tertiary ether, separating the unreacted hydrocarbons and decomposing the tertiary ether formed in the presence of an acidic High temperature catalyst using a primary C3 or C4 alcohol and the exit temperature of the reaction mixture from the etherification stage for the formation of the tertiary ether is lower than the mean temperature in the etherification stage. |
