HCID 86972-Ethylhexanoic AcidYield 96%

Procedure

12.82kg/h of 2-ethylhexanal and 1.79kg/h of oxygen (molar ratio 1:0.56) were caused to react in the presence of 1.9wt% of potassium 2-ethylhexanoate (prepared by the addition of KOH to the initial reaction mixture) at 40° C. and a pressure of 3 bar. 96 % of 2-ethylhexanoic acid having a color value of 4 were isolated by distillation (determined as specified in ISO 6271 ). The bottoms were recycled to the oxidation stage.
