- PROCESS FOR PRODUCING DIHYDROXYBENZENE AND DIISOPROPYLBENZENDICARBINOL
-
A process for simultaneously producing a dihydroxybenzene and a diisopropylbenzene dicarbinol, which contains subjecting a diisopropylbenzene with an oxygen containing gas to obtain an oxidation reaction mixture containing a diisopropylbenzene dihydroperoxide and a diisopropylbenzene hydroxy hydroperoxide followed by an extraction separation step, a decomposition step, a distillation separation step, a reduction step and a post-treatment step in this order, the process containing purifying the diisopropylbenzene dicarbinol from the liquid containing the diisopropylbenzene dicarbinol obtained in the reduction step through purification operations containing crystallization, filtration and subsequent drying, and supplying a filtrate obtained by the filtration to the decomposition step and/or distillation separation step.

- Process for the production of a dihydroxybenzene and dicarbinol from diisopropylbenzene
-
Improved methods for the simultaneous production of dihydroxybenzene and dicarbinol from diisopropylbenzene are provided. These methods provide for continuous and simultaneous production of diisopropylbenzene dihydroperoxide (DHP) and diisopropylbenzene hydroxyhydroperoxide (HHP) using Karr Column extractors operated in series. A very high purity DHP-containing solution, the precursor to the dihydroxybenzene, can be produced according to the reported methods. A safe and efficient method for producing dicarbinol from HHP is also disclosed.

- SYNTHESIS OF HYDROXYPEROXIDES AND PEROXIDE MONOMERS BASED ON 1,3-DIISOPROPYLBENZENE
-
In the reaction of 1,3-di(1-hydroxy-1-methylethyl)benzene with 2-hydroperoxy-2-methylpropane and 2-hydroperoxy-2-phenylpropane the corresponding hydroxyperoxides were obtained.Their dehydration gave the unsaturated peroxides.
