  • Patent number: 11014883
    Abstract: Disclosed are novel processes for the production of cyclic imide compounds such as N-hydroxyphthalimide (NHPI). The processes may be particularly well-suited for commercial-scale production of cyclic imides such as NHPI. Such cyclic imide compounds are suitable for use as oxidation catalysts, and specifically may be used to oxidize cyclohexylbenzene to cyclohexyl-1-phenyl-1-hydroperoxide. Such an oxidation may be particularly useful in a process for the production of phenol and/or cyclohexanone from benzene via a process comprising hydroalkylation of benzene to cyclohexylbenzene, oxidation of the cyclohexylbenzene to cyclohexyl-1-phenyl-1-hydroperoxide, and cleavage of the cyclohexyl-1-phenyl-1-hydroperoxide to phenol and cyclohexanone. The cyclic imide production process may advantageously include water washing and reactant recovery steps to maximize purity and yield.

  • Patent number: 10584096
    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.

  • Patent number: 10259765
    Abstract: Disclosed are novel processes for making cyclohexanone compositions, from a mixture comprising phenol, cyclohexanone, and cyclohexylbenzene. The process includes hydrogenation of a feed stream comprising phenol, cyclohexanone, and cyclohexylbenzene. The feed stream may be subjected to one or more pre-hydrogenation treatments, such as passing through one or more sorbents, addition of basic chemical agents, and/or addition of water, so as to improve catalyst activity, minimize undesired side reactions, and/or remove catalyst poisons from the feed stream. The feed stream may be provided to a hydrogenation reaction zone in the vapor phase, with periodic alterations to hydrogenation reaction conditions such that the feed is provided in mixed liquid and vapor phase in order to carry out liquid washing of a hydrogenation catalyst bed within the hydrogenation reaction zone.
