AI Technical Summary
Technical Problem
In the existing 2-ethylhexanoic acid manufacturing method, the catalyst cost is high, the reaction temperature is high, and a lot of by-products are generated, resulting in low product yield and environmental pollution.
Method used
Under low temperature conditions of 0 to 30°C, use the reaction mixture of 2-ethylhexanal and solvent and oxygen-containing gas to carry out oxidation reaction under the action of catalyst. The reaction speed and selectivity are improved through external circulation stirring. Selective catalysts such as Mn (Ac)2, KAc or Cu(Ac)2 to reduce costs.
Benefits of technology
It achieves high selectivity and high yield of 2-ethylhexanoic acid, reduces catalyst cost, reduces by-product formation, and improves reaction efficiency.
