Patent ID: 7148388

Claim:
A process for producing a long chain alcohol mixture comprising contacting at least part of the olefinic hydrocarbon mixture produced by preparing an olefinic hydrocarbon mixture comprising at least 5% by weight of mono-olefin oligomers of the empirical formula; C n H 2n where n is greater than or equal to 6, said mono-olefin oligomers comprising at least 20 percent by weight of olefins having at least 12 carbon atoms, said olefins having at least 12 carbon atoms having an average of from about 0.8 to about 2.0 C 1 –C 3 alkyl branches per carbon chain, wherein at least 50% of the branches in the olefins having at least 12 carbon atoms comprising methyl and ethyl branches located at the odd-numbered position in the carbon chain, said process for preparing an olefinic hydrocarbon mixture comprising contacting a feedstock comprising n-butene and propylene in a molar ratio of about 1:0.01 to about 1:0.49 under oligomerization conditions with surface deactivated ZSM-23, wherein said ZSM-23 has been surface deactivated with a sterically hindered nitrogenous base, with carbon monoxide and hydrogen under hydroformylation conditions and in the presence of a hydroformylation catalyst.
