  • Publication number: 20210220507
    Abstract: Embodiments of the invention comprise disinfection and deodorization equipment employing ultraviolet light (UV-A) as an energy source in the Photo-catalytic process for cleaning environments where Microbial pathogens or Volatile organic compounds are present causing Hospital Acquired Infections (HAI) or malodors. In one embodiment of the invention, disinfection and deodorizing equipment comprises a Reaction Chamber having an inlet for receiving air and an outlet for discharging clean air by Photo-catalysis process which in turn accelerates the oxidization process in the atmosphere and decomposes any airborne toxic or volatile organic matter. The reaction chamber may further comprise a plurality of segmented baffles with various sizes, shapes and designs.

  • Patent number: 9234054
    Abstract: A process comprising reacting a 2-indenylboranic acid (ester) with a bromosubstituted compound in the presence of the Pd catalyst bis(triphenylphosphin)palladium dichloride and a base to form the corresponding bridged bis(indenyl) ligand. Where the 2-indenylboranic acid (ester) is the pinacolester of 2-indenylboranic acid, the process may further comprise reacting a 2-bromo indene compound with pinacolborane in the presence of a Pd catalyst and a base to form the corresponding 2-indenylpinacolylborane compound. Bridged bis(indenyl)ligands may suitably be used in the preparation of metallocene complexes, such as 2,2?-bis(2-indenyl)biphenyl ZrCl2 and 1,2-bis (2-indenyl)benzene ZrCl2. These metallocene complexes may be used for the polymerization, optionally in the presence of a cocatalyst, of one or more ?-olefins, preferably for the polymerization of ethylene.

  • Patent number: 9000200
    Abstract: A process to prepared bridged bis(indenyl)ligands, comprising the step of reacting a 2-indenylpinacolyl borane compound with a bromosubstituted compound in the presence of a Pd catalyst and a base to form the corresponding bridged bis(indenyl) ligand. The process may further comprise the step of reacting a 2-bromo indene compound with pinacolborane in the presence of a Pd catalyst and a base to form the corresponding 2-indenylpinacolylborane compound. These bridged bis(indenyl)ligands may suitably be used in the preparation of metallocene complexes, such as 2,2?-bis(2-indenyl)biphenyl ZrCl2 and 1,2-bis(2-indenyl)benzene ZrCl2. These metallocene complexes may be used for the polymerization, optionally in the presence of a cocatalyst, of one or more ?-olefins, preferably for the polymerization of ethylene.
