Abstract
2,3-dimethylbutene-1 (2,3-DMB1) is produced from propene by a process comprising the steps of: PA0 (A) converting propene in one or more stages to a product comprising 2,3-dimethylbutene-2 (2,3-DMB-2) under conditions whereby the proportion of 2,3-DMB-2 in the product is maximised, PA0 (B) separating 2,3-DMB-2 from the product of step (A), and PA0 (C) contacting the 2,3-DMB-2 separated in step (B) with a catalyst active for the isomerisation of 2,3-DMB-2 to 2,3-DMB-1 under conditions whereby 2,3-DMB-2 is isomerised to 2,3-DMB-1.
