  • Patent number: 9169170
    Abstract: An alkylating process such as hydroalkylating process comprising feeding a gas material and a liquid material into the reactor, distributing the liquid material to the upper surface of a bed of a catalyst substantially uniformly. The substantial uniform distribution of the liquid material to the upper surface allows for substantially uniform distribution of liquid reaction medium in the bed, thereby preventing hot spot and undesirable continuous liquid zone, both of which can cause the production of undesired by-products. The invention is particularly useful for the hydroalkylation reaction of benzene in making cyclohexylbenzene, which can be used for making cyclohexanone and phenol.

  • Publication number: 20150065339
    Abstract: Catalysts prepared from abundant, cost effective metals, such as cobalt, nickel, chromium, manganese, iron, and copper, and containing one or more neutrally charged ligands (e.g., monodentate, bidentate, and/or polydentate ligands) and methods of making and using thereof are described herein. Exemplary ligands include, but are not limited to, phosphine ligands, nitrogen-based ligands, sulfur-based ligands, and/or arsenic-based ligands. In some embodiments, the catalyst is a cobalt-based catalyst or a nickel-based catalyst. The catalysts described herein are stable and active at neutral pH and in a wide range of buffers that are both weak and strong proton acceptors. While its activity is slightly lower than state of the art cobalt-based water oxidation catalysts under some conditions, it is capable of sustaining electrolysis at high applied potentials without a significant degradation in catalytic current. This enhanced robustness gives it an advantage in industrial and large-scale water electrolysis schemes.

    Abstract: In a process for oxidizing an alkylaromatic compound to the corresponding hydroperoxide, a feed comprising an alkylaromatic compound is contacted with an oxygen-containing gas in the presence of a catalyst comprising a cyclic imide. The contacting is conducted at a temperature of about 90° C. to about 150° C., with the cyclic imide being present in an amount between about 0.05 wt % and about 5 wt % of the alkylaromatic compound in the feed and the catalyst being substantially free of alkali metal compounds. The contacting oxidizes at least part of the alkylaromatic compound in said feed to the corresponding hydroperoxide.

  • Publication number: 20130231506
    Abstract: Disclosed herein is a process for producing phenol. The process includes oxidizing at least a portion of a feed comprising cyclohexylbenzene to produce an oxidation composition comprising cyclohexyl-1-phenyl-1-hydroperoxide. The oxidation composition may then be cleaved in the presence of an acid catalyst to produce a cleavage reaction mixture comprising the acid catalyst, phenol and cyclohexanone. At least a portion of the cleavage reaction mixture may be neutralized with a basic material to form a treated cleavage reaction mixture. In various embodiments, the cleavage reaction mixture contains 1 wt % to 30 wt % phenol, 1 wt % to 30 wt % cyclohexanone and a complexation product.

  • Publication number: 20130225867
    Abstract: In a process for producing phenol and cyclohexanone, a feed comprising cyclohexylbenzene is oxidized to produce an oxidation reaction product comprising cyclohexyl-1-phenyl-1-hydroperoxide. At least a portion of the oxidation reaction product is then cleaved to produce a cleavage reaction product comprising phenol, cyclohexanone, and at least one contaminant. At least a portion of the cleavage reaction product is contacted with an acidic material to convert at least a portion of the at least one contaminant to a converted contaminant and thereby produce a modified reaction product. The cleavage reaction product may comprise 1 wt %-30 wt % phenol; 1 wt %-30 wt % cyclohexanone; and 0.

  • Publication number: 20130225856
    Abstract: This specification discloses an operational continuous process to convert lignin as found in ligno-cellulosic biomass before or after converting at least some of the carbohydrates. The continuous process has been demonstrated to create a slurry comprised of lignin, raise the slurry comprised of lignin to ultra-high pressure, deoxygenate the lignin in a lignin conversion reactor over a catalyst which is not a fixed bed without producing char. The conversion products of the carbohydrates or lignin can be further processed into polyester intermediates for use in polyester preforms and bottles.

  • Publication number: 20130204046
    Abstract: A hydride transfer process within a reaction between an alcohol and a ketone and in the presence of a heterogeneous catalyst is described. The process can transfer a hydride from an alcohol to a ketone, thus enabling reduction of the ketone and oxidation of the alcohol. Further described, is a process for the simultaneous preparation of cyclohexanone and isopropanol enabling an optimized industrial operation. A mixture of compounds useful for implementing the process and comprising two different ketones and two different alcohols is also described.

  • Publication number: 20130079545
    Abstract: A regio-selective and consecutive Michael-Claisen process has been developed for substituted cyclohexane-1,3-dione synthesis started from unsubstituted or substituted acetone and ?,?-unsaturated esters. Substituted cyclohexane-1,3-diones are the basic unit found in several natural products, bioactive alkaloids and acridine dione type heterocycles, polyphenols, and unnatural amino acid synthesis. Most of the potent herbicidal and pesticidal active molecules contain cyclohexane-1,3-dione derivatives. Such an important intermediate synthesis using a facile, atom economy and one-pot process is a demandable area in organic synthesis.
