Abstract: This invention relates to a process for producing an olefin product having an enhanced alpha olefin content from an olefin feedstock containing internal olefins or a mixture of internal and alpha olefins which includes:(a) contacting the feedstock with an anthracene and a double-bond isomerization catalyst at a temperature ranging from about 150.degree. to about 275.degree. C. to form an olefin adduct with anthracene,(b) separating the adduct from the product of step (a),(c) heating the separated adduct at a temperature ranging from about 250.degree. to about 400.degree. C. to produce anthracene and an olefin product enhanced in alpha olefin content over the alpha olefin content of the feedstock, and(d) separating anthracene from the product of step (c) to produce the product enhanced in alpha olefin.Linear olefins are a preferred feedstock.

Abstract: This invention relates to a process for converting saturated aliphatic primary alcohols to aldehydes by passing said alcohols over a fixed bed of brass catalyst particles at a temperature ranging from about 375.degree. to about 550.degree.

Abstract: A process for selectively hydrogenating a polymer containing ethylenic unsaturation and cyano groups with a catalyst prepared by combining one or more of certain palladium compounds and one or more of alkylalumoxanes in a suitable solvent or diluent. The hydrogenation is accomplished in a suitable solvent for the polymer at a temperature within the range from about 20.degree. C. to about 175.degree. C. at a total pressure within the range from about 50 to about 1,000 psig and at a hydrogen partial pressure within the range from about 50 to about 950 psig. The hydrogenation can be accomplished so as to convert at least about 85% of the ethylenic unsaturation contained initially in the polymer without converting a significant portion (less than about 5%) of the cyano groups to amine groups.
