Hydroformylation of olefins is carried out in two steps R1 and R2 in a reactor system, whereby the olefin containing feed, carbon monoxide, hydrogen and the discharge from R1 is fed to R2

摘要

A process for the hydroformylation of olefins by the reaction of carbon monoxide and hydrogen in the presence of a hydroformylation catalyst in carried out in two steps (R1) and (R2) in a reactor system, whereby the olefin containing feed, carbon monoxide, hydrogen and the discharge from R1 is fed to reaction step R2 and partially reacted, catalytically and the output from (R1) is fed to (R2). A process for the hydroformylation of olefins by the reaction of carbon monoxide and hydrogen in the presence of a hydroformylation catalyst in carried out in two steps (R1) and (R2) in a reactor system, whereby -the olefin containing feed, carbon monoxide, hydrogen and the discharge from R1 is fed to reaction step R2 and partially reacted, catalytically -the discharge from (R2) is separated to form a catalyst containing liquid fraction (F1), a product containing fraction (F2) and an unreacted olefin containing fraction (F3) -at least some of the fraction (F3), optionally with at least some of the fraction (F1) as well as carbon monoxide and/or hydrogen are fed to reaction step (R1) and catalytically reacted -the output from (R1) is fed to (R2)
