Open the CIPO recordAbstract From the Canadian patent
A method is disclosed for producing branched aliphatic ketones in hydrocarbon mixtures from isoalkanes by a superacid catalyzed formylation-rearrangement reaction. The method can be used to simultaneously isomerize if necessary, and formylate hydrocarbons in complex hydrocarbon mixtures such as refinery streams, alkylate mixtures, and natural gas liquids. Natural gas liquids of low octane number are upgraded and oxygenated by adding to the natural gas liquids or reactively producing in the liquids branched aliphatic ketones.

Why it's free to use
- Filed May 6, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 6, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 6, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
