  • Patent number: 8298610
    Abstract: This invention provides processes for inhibiting the formation of copper oxides on substantially oxide-free copper surfaces by contacting a substantially oxide-free copper surface with a bifunctional ligand that contains both a metal-coordinating group and a tertiary amine group in an aqueous solution of pH about 2 to about 5.5. A thin layer of the bifunctional ligand formed by coordination of the dialkylaminoacetonitrile to the copper surface can be removed by heating under vacuum to regenerate a substantially oxide-free copper surface.

  • Patent number: 8110382
    Abstract: A process is provided for producing glycolic acid from formaldehyde and hydrogen cyanide. More specifically, heat-treated formaldehyde and hydrogen cyanide are reacted to produce glycolonitrile having low concentrations of impurities. The glycolonitrile is subsequently converted to an aqueous solution of ammonium glycolate using an enzyme catalyst having nitrilase activity derived from Acidovorax facilis 72W (ATCC 57746). Glycolic acid is recovered in the form of the acid or salt from the aqueous ammonium glycolate solution using a variety of methods described herein.

  • Patent number: 7632351
    Abstract: This invention is directed to processes for the formation of ruthenium-containing films on surfaces in atomic layer deposition (ALD) processes. The ALD process includes depositing a surface-activating group on the surface; exposing the deposit of the surface-activating complex to a ruthenium precursor to form a deposited ruthenium complex on the surface; and reacting the deposited ruthenium complex with a reducing agent to form a ruthenium-containing film on the surface. This invention is also directed to ruthenium complexes, RuL2L*, that can be used as ruthenium precursors in these processes.
