摘要： A process for preparing C9-alcohols comprises a) providing a C4-hydrocarbon stream comprising butene and butane; b) subjecting the C4-hydrocarbon stream to oligomerization over an olefin oligomerization catalyst and fractionating the resulting reaction mixture to give an octene-containing stream and a butene-depleted C4-hydrocarbon stream; c) subjecting the butene-depleted C4-hydrocarbon stream to steam reforming or partial oxidation to give carbon monoxide and hydrogen; d) hydroformylating the octene-containing stream by means of carbon monoxide and hydrogen in the presence of a hydroformylation catalyst to form C9-aldehydes, where the carbon monoxide used and/or the hydrogen used originate at least in part from step c); and e) catalytically hydrogenating the C9-aldehydes by means of hydrogen. In a variant of the process, part of the butenes present in the C4-hydrocarbon stream are hydroformylated to form C5-aldehydes, these are subjected to an aldol condensation and the product of the aldol condensation is hydrogenated to form C10-alcohols. The process allows the C4-hydrocarbon stream used to be substantially utilized as material.
