  • Patent number: 10320023
    Abstract: Titanium catecholate complexes can be desirable active materials for flow batteries and other electrochemical energy storage systems, particularly when incorporated in aqueous electrolyte solutions. It can be desirable to avoid introducing even traces of certain organic solvents into aqueous electrolyte solutions. Neat methods for synthesizing titanium catecholate complexes can help avoid the unwanted introduction of trace organic solvents into aqueous electrolyte solutions and also provide further advantages. Methods for synthesizing titanium catecholate complexes can include: combining a catechol compound and a titanium reagent in an absence of solvent to produce a reaction mixture, and reacting the titanium reagent with the catechol compound in a neat state to form a titanium catecholate complex containing at least one catecholate ligand. The titanium catecholate complex can be further reacted with a base to produce a salt form titanium catecholate complex, which can be present in an aqueous phase.

  • Patent number: 8097149
    Abstract: Oil soluble catalysts are used in a process to hydrodesulfurize petroleum feedstock having a high concentration of sulfur-containing compounds and convert the feedstock to a higher value product. The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.

  • Publication number: 20040048991
    Abstract: It has been discovered that using n-butylmethyldimethoxysilane (BMDS) as an external electron donor for Ziegler-Natta catalysts can provide a catalyst system that may prepare polypropylene films with improved properties. The catalyst systems of the invention provide for controlled chain defects/defect distribution and thus a regulated microtacticity. Consequently, the curve of storage modulus (G′) v. temperature is shifted such that the film achieves the same storage modulus at a lower temperature enabling faster throughput of polypropylene film through a high-speed tenter.
