Abstract
Official abstract text for this publication.
A process for preparing isobutene by dissociation of MTBE, including: a) reaction of isobutene-containing hydrocarbon mixtures, with methanol, present in one or more methanol-containing streams, over acidic ion exchangers to give a stream, containing MTBE and TBA; b) separation of a stream containing MTBE and TBA, from a stream by distillation; c) dissociation of a stream in the gas phase over a heterogeneous catalyst to give a stream containing at least isobutene, methanol, MTBE and water and possibly TBA, d) separation of a stream by distillation to give a stream containing in each case more than 50% by mass of the amounts of methanol, TBA and water present in another stream and a stream containing isobutene, e) separation of water from stream to below 1% by mass by distillation to give a stream, f) total or partial recirculation of the methanol-containing stream.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for preparing isobutene, the process comprising: (a) reacting at least one hydrocarbon mixture comprising isobutene with at least one alcohol stream comprising methanol, over at least one acidic ion exchanger to give a first stream comprising methyl tert-butyl ether and tert-butanol; (b) separating the first stream by distillation to obtain a second stream comprising methyl tert-butyl ether and tert-butanol; (c) dissociating the second st…
