Abstract: A feed mixture comprising at least one C3 olefin and/or at least one C4 olefin may be contacted with a zeolite catalyst under oligomerization reaction conditions to form a product mixture comprising a plurality of olefin oligomers comprising C12 and/or C16 olefin oligomers having an average branching index, as measured by gas chromatography, of about 2.2 or less, such as about 1.3 to about 2.0. The olefin oligomers may be contacted with a syngas mixture comprising carbon monoxide and hydrogen in the presence of a hydroformylation catalyst to form a hydroformylation reaction product, which may be subsequently reduced to form a plurality of branched alcohols. The branched alcohols, in turn, may be converted into an amphiphilic compound, such as a plurality of branched alcohol sulfates.

Abstract: The present invention relates to processes for preparing isoprene and mono-olefins comprising at least six carbon atoms. In one aspect, a process comprises (a) hydroformylating a mixed C4 olefin stream, wherein the mixed C4 olefin stream comprises 1-butene, 2-butene, and optionally isobutene, with a hydroformylation catalyst, wherein the hydroformylation catalyst comprises rhodium with monodentate organophosphorous ligand and optionally polydentate organophosphorous ligand, to produce a mixture comprising linear and branched C5 aldehydes; (b) separating the branched C5 aldehydes from the linear C5 aldehydes to provide a branched C5 aldehyde stream and a linear C5 aldehyde stream; (c) dehydrating the branched C5 aldehydes in the branched C5 aldehyde stream using a dehydration catalyst to form a stream comprising isoprene; (d) hydrogenating the linear C5 aldehydes in the linear C5 aldehyde stream to form a C5 alcohol stream; (e) dehydrating the C5 alcohols in the C5 alcohol stream with a second dehydration catalyst to form a C5 olefin stream; (f) hydroformylating the C5 olefins in the C5 olefin stream to generate a C6 aldehyde stream; (g) hydrogenating the C6 aldehydes in the C6 aldehyde stream to form a C6 alcohol stream; and (h) dehydrating the C6 alcohols in the C6 alcohol stream with a third dehydration catalyst to form a C6 olefin stream.
