Abstract
Provided herein is a cyclic imide slurry composition and processes for forming and/or using such a composition. The slurry composition comprises solid cyclic imide and organic liquid, such as liquid alkylbenzene, liquid cyclohexane, and/or liquid organic alcohol (such as cyclohexanol). The slurry composition may find particular use in processes in which the cyclic imide serves as an oxidation catalyst (e.g., as a radical initiator). For instance, the slurry composition may be useful in the oxidation of a liquid alkylbenzene such as cyclohexylbenzene to corresponding 1-cyclohexyl-1-phenyl hydroperoxide. Such an oxidation reaction may further be part of an integrated process for the production of phenol and/or cyclohexanone from benzene via hydroalkylation to form cyclohexylbenzene.
