  • 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.

  • Publication number: 20120157658
    Abstract: This invention relates to methods, compositions, and apparatuses for producing macrocyclic compounds. First, one or more reactants are provided in a reaction medium, which are capable of forming the macrocyclic compound through a desired reaction pathway that includes at least cyclization, and which are further capable of forming undesired oligomers through a undesired reaction pathway that includes undesirable oligomerization. Oligomerization of such reactions in the reaction medium is modulated to reduce formation of undesired oligomers and/or to reduce separation of the undesired oligomers from the reaction medium, relative to a corresponding unmodulated oligomerization reaction, thereby maximizing yields of the macrocyclic compound. The macrocyclic compound so formed is then recovered from the reaction medium. Preferably, the macrocyclic compound spontaneously separates from the reaction medium via phase separation.

  • Publication number: 20100317895
    Abstract: In a process for producing cyclohexylbenzene, hydrogen and a liquid feed comprising benzene are introduced into a reaction zone and are contacted in the reaction zone under hydroalkylation conditions to produce cyclohexylbenzene. An effluent stream comprising cyclohexylbenzene and unreacted benzene is removed from the reaction zone and is divided into at least first and second portions, wherein the mass ratio of the effluent stream first portion to the effluent stream second portion is at least 2:1. The effluent stream first portion is then cooled and the cooled effluent stream first portion is recycled to the reaction zone.

  • Publication number: 20100305337
    Abstract: The present invention relates to the preparation of compounds of the general formula II which can be obtained by 1,4 addition of 2-oxoalkanoates or 2-oxocarboxylic acids onto the appropriate ketones. The present invention also relates to the use of the PigD protein for catalysis of 1,4 additions of 2-oxoalkanoates/-carboxylic acids, for example pyruvate/pyruvic acid or 2-oxobutyrate/2-oxobutyric acid, onto aliphatic, aromatic and heterocyclic ?,?-unsaturated ketones. The 1,4 additions are effected here with CO2 elimination. The use of the PigD protein as a catalyst in the aforementioned 1,4 additions enables the synthesis of addition products with stereoactive centers these addition products being preparable with an enantiomeric excess of more than 80% ee.
