Open the CIPO recordAbstract From the Canadian patent
A process far the production of olefins and diolefins, such as 1,3-butadiene, comprising contacting an aliphatic hydrocarbon, such as butane with a, heterogeneous catalyst composition containing reactive oxygen under reaction conditions such that a more highly unsaturated aliphatic hydrocarbon is selectively formed in a high productivity. The catalyst is a composition comprising a catalyst component of magnesia an oxide of, molybdenum, a Group IA metal oxide promoter and, optionally vanadium oxide. In a preferred embodiment the catalyst composition also comprises a support component of magnesium and alumina and/or magnesium aluminate spinel. The present catalyst has high surface area and …

Why it's free to use
- Filed July 19, 1990 and granted November 7, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 19, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 19, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
