Olefins are oxidized to carbonyl compounds, for example, 1-hexene to 2-hexanone, with a Pd/Cu/alkali metal or alkaline earth metal chloride catalyst and a suitable surfactant in a diluent system comprising at least two liquid phases, wherein at least one liquid phase is an aqueous phase, in the presence of free oxygen. The addition of the surfactant to the system provides an improvement in olefin conversion and selectivity to the corresponding carbonyl compound. Suitable surfactants include, for example, quaternary ammonium halide compounds.
在由至少两个液相(其中至少一个液相是
水相)组成的稀释剂体系中,在存在自由氧的情况下,使用
钯/

金属
氯化物催化剂和合适的表面活性剂将烯烃氧化成羰基化合物,例如将
1-己烯氧化成
2-己酮。 在该体系中添加表面活性剂可提高烯烃转化率和对相应羰基化合物的选择性。 合适的表面活性剂包括季
铵卤化物等。
