A method for the production of c5 - aldehydes and propene of a 1 - butene - and 2 - butene - glycol-containing c4 - current

摘要

A method for the production of c₅-Aldehydes and propene of a 1 - butene - and 2 - containing butenes - c₄-Current, the up to 1000 w - ppm of 1,3 - of butadiene (c.₄-Input current), comprisinga) a hydroformylation stage, in which the c₄-Input current in the presence of a conventional hydroformylation catalyst with hydrogen and carbon monoxide in the contact and the resulting c.₅-Aldehydes and to the thus formed 2 - butene -, c₄-Current then separated from one another, andb) a metathesis step, in which is formed in the hydroformylation stage 2 - butene -, c₄-Current in the presence of a conventional metathesis catalyst brought into contact with ethene and of the formed in the process, propene - containing hydrocarbon stream separates the propene.
