Method for concentrating an organic hydroperoxide mixture comprising a hydrocarbon and a hydroperoxide corresponding thereto comprises evaporating a first liquid mixture in a thin-film evaporation device followed by separation in a separation zone. Both the evaporation device and the separation zone operate at a low absolute pressure at a temperature lower than the thermal degradation temperature of the hydroperoxide to prevent thermal decomposition thereof. The process is particularly useful for concentrating an oxidation product made from the oxidation of cyclohexylbenzene.
一种用于浓缩含有碳氢化合物和相应的有机过氧化物的混合物的方法,包括在薄膜蒸发装置中蒸发第一液体混合物,然后在分离区分离。蒸发装置和分离区都在低于过氧化物热降解温度的温度下以低绝对压力运行,以防止其热分解。该过程特别适用于浓缩由
环己基苯氧化而成的氧化产物。
