Process for liquid-phase oxidation of m-diisopropylbenzene |
| 摘要 |
A process for producing m-diisopropylbenzene dihydroperoxide which comprises oxidizing m-diisopropylbenzene in the liquid phase with molecular oxygen under alkaline conditions; wherein the oxidation is carried out under conditions (A), (B) and (C) below, (A) under conditions which meet (i), (ii), (iii) and (iv) below, (i) 0</=x</=140 (ii) y>/=80 (iii) -0.05x+110>/=y>/=-0.15x+95 wherein 0</=x</=100 (iv) y</=-0.25x+130 wherein 100<x</=140 in which x represents the absolute value of the concentration of hydroperoxides in the oxidation product in % by weight calculated as m-diisopropylbenzene monohydroperoxide, and y represents the absolute value of the reaction temperature in degrees centigrade, (B) until x reaches at least 120, and (C) so that the reaction temperature at 100<x</=140 is lower than the reaction temperature at the start of the reaction (x=0).
