Abstract: In the continuous prodn. of alkyl pentenoates (I) by reacting 4 C fractions (II) contg. butadiene (IIA) with alkanols and CO in the presence of Co carbonyl catalysts (III) and heterocyclic aromatic tert. N bases at 100-160 deg.C and 400-1200 bar, the reaction mixt. is passed through a treatment zone, without back-mixing, as it is formed at 100-160 deg.C, pressure of 250-1200 bar and dwell time of 5-60 min.

Abstract: A method for the continuous production of alkyl esters of pentenric acid by reacting butadiene-containing C4 sections with alkanols and carbon monoxide in the presence of cobalt carbonyl catalysts and heterocyclic aromatic tertiary nitrogen bases at a temperature of 100 to 160 DEG C and under a pressure of 100 to 1200 bar, characterised in that the reaction mixture is passed essentially without remixing through a treatment zone at the rate at which it is formed at a temperature of 100 to 160 DEG C under a pressure of 250 to 1200 bar and with a residence time of 10 to 60 minutes.
