  • Patent number: 10968284
    Abstract: The present invention is a multilayered composite comprising porous metal oxide particles that are covalently bonded by way of inorganic ether groups to one or more sites of a first polyhydroxyl-functionalized polymer. This first polymer is in turn covalently bonded by way of inorganic ether groups to one or more sites of a second polyhydroxyl-functionalized polymer. The multilayered composites can be prepared by contacting porous inorganic-oxide particles with a sufficient amount of OH-reactive crosslinking agent to form metal oxide particles imbibed with the crosslinking agent, and then contacting the inorganic-oxide particles with a solution of polyhydroxyl-functionalized polymer under reactive conditions.
    Type: Grant

  • Patent number: 9790143
    Abstract: Provided is a method of alkylating an aromatic compound comprising contacting an aromatic compound and an alkylating agent in the presence of UCB-3 as a catalyst under reaction conditions suitable for aromatic alkylation. The aromatic compound preferably comprises benzene or toluene and the alkylation agent preferably comprises an olefin or alcohol. Lower temperature ranges can be used for the reaction, for example in the range of from 100 to 300° C.

  • Patent number: 9687830
    Abstract: Provided is a process of conducting a Baeyer-Villiger oxidation which comprises contacting a ketone and an oxidant in the presence of an Sn-DZ-1 catalyst to thereby oxidize the ketone to an ester. The Sn-DZ-1 catalyst comprises Sn heteroatoms on the external surface of the zeolitic material lattice framework, and B heteroatoms, or silanols created from boron hydrolysis, throughout the remainder of the lattice framework.

  • Patent number: 9636669
    Abstract: A zeolite material is provided having non-boron heteroatoms on the external surface of the zeolitic material lattice framework and B heteroatoms, or silanols created from boron hydrolysis, throughout the remainder of the lattice framework. The lattice framework of the zeolite material comprises large pore 12 member ring or larger openings at the external surface of the framework, and 10 member ring or smaller openings beneath the external surface large pore openings. Also provided is a process for preparing the zeolitic material.

  • Patent number: 9266915
    Abstract: The present invention is directed to the synthesis of novel stable open metal clusters by selective oxidation of bound ligands. The synthesis comprises, for example, using an amine based oxidant for decarbonylation of specific carbonyl ligands. The synthesis can also comprise further removal of a bound amine group by an acid. The resulting metal cluster contains a coordinatively unsaturated site comprising a carbonyl vacancy. The resulting metal cluster can be used as a catalyst in a variety of chemical transformations.
