Process for the partial dehydration of a crude water-wet organic stream of the monohydroperoxide of p-diisopropylbenzene

摘要

A process for the partial dehydration and partial purification of a crude water-wet organic stream of the monohydroperoxide of p-diisopropylbenzene is disclosed. This crude stream of monohydroperoxide contains at least 2 wt % water and is partially dehydrated by contacting the stream with a non-reactive inorganic salt to remove a portion of the water into a concentrated brine of the inorganic salt followed by separation of the concentrated brine and the product. The crude water-wet organic stream of the monohydroperoxide is optionally filtered and coalesced prior to contacting the nonreactive inorganic salt.
