VERFAHREN ZUR KONTINUIERLICHEN HERSTELLUNG VON CARBALKOXYGRUPPEN ENTHALTENDEN ALIPHATISCHEN VERBINDUNGEN

Carbalkoxy-containing aliphatic compounds are prepared continuously by reacting an olefinically unsaturated aliphatic compound with carbon monoxide and an alkanol in the presence of a cobalt carbonyl catalyst and a tertiary nitrogen base at from 80 DEG to 200 DEG C. and under from 100 to 1,200 bar b...

Zusammenfassung:Carbalkoxy-containing aliphatic compounds are prepared continuously by reacting an olefinically unsaturated aliphatic compound with carbon monoxide and an alkanol in the presence of a cobalt carbonyl catalyst and a tertiary nitrogen base at from 80 DEG to 200 DEG C. and under from 100 to 1,200 bar by an improved process in which carbon monoxide is circulated, and a carbon dioxide content of from 0.1 to 2% by volume is maintained in the carbon monoxide fed to the reaction.
