A process for dimerizing vinyl olefins that is fully integrated into a process for making vinyl olefins is disclosed.

Integrated dimerization process

A method for the isomerization of a mixture of vinyl and vinylidene olefins having 10 to 35 carbons atoms to form a mixture comprising both di- and tri-substituted internal olefins including deep internal olefins.

Isomerization process of a mixture containing vinyl and vinylidene olefins

A process for oligomerizing an acyclic monoolefin monomer in which the oligomerization is controlled to produce predetermined relative amounts of at least two preselected oligomers in a higher boiling fraction of the oligomerization products and the lower boiling products are recycled to the oligomerization reaction.

Oligomerization process

Isomerization catalyst and process

A process for producing an internal olefin of the formula ##STR1## where R.sup.1 and R.sup.2 are the same or different and are either a hydrogen or an alkyl and m is an integer of from 0 to 20 comprising contacting a vinyl or vinylidene olefin of the formula ##STR2## where R.sup.1, R.sup.2 and m are as previously defined, with a catalytically effective amount of a mixture of i) an aluminum compound of the formula R.sup.3.sub.n Al(OR.sup.4).sub.p where R.sup.3 and R.sup.4 are the same or different and are alkyl, n is an integer from 0.75 to 2.25, and p is an integer from 0.75 to 2.25, the sum of n and p being 3, and ii) a cobalt (II) salt of an organic carboxylic acid, at a temperature of from about 25.degree. C. to about 250.degree. C. whereby a major amount of said internal olefin is produced and only a minor amount of a tri-substituted internal olefin.

Aluminum alkyls are oxidized to aluminum alkoxides using a cobalt catalyst to increase the rate of oxidation. Alcohols can be prepared by hydrolysis of the aluminum alkoxides.

Method of oxidizing aluminum alkyls

This invention povides to a process for making an aluminum trialkyl product which process comprises reacting a mixture comprising, (i) an aluminum alkyl feed which contains one or more aluminum alkyls represented by the formula R.sub.3 Al, where R represents a C.sub.2 to C.sub.20 straight chain alkyl radical and each R can be the same or different, the alkyl radicals in said aluminum alkyl feed having an average chain length of at least about C.sub.8, and (ii) a linear alpha-olefin feed which contains one or more linear alpha-olefins, said alpha-olefin feed having an average chain length which is at least about 2 carbons greater than the average chain length of the alkyl radicals in said aluminum alkyl feed, in the presence of a catalytic amount of a cobalt displacement catalyst, the reaction being at a temperature sufficient to displace olefins corresponding to R from said aluminum alkyl feed and to substitute in their place alkyl radicals derived from said linear alpha-olefin feed so as to form an aluminum trialkyl product having an average alkyl chain length which is greater than said aluminum alkyl feed, and the reaction being under sub-atmospheric pressure such that displaced olefins are removed form the reaction mixture. Long chain, linear alcohols can be prepared by oxidation and hydrolysis of the aluminum trialkyl products.
