  • Patent number: 6787671
    Abstract: An osmium-assisted process for the oxidative cleavage of oxidizable organic compounds such as unsaturated organic compounds, including alkenes and olefins into aldehydes, carboxylic acids, esters, or ketones. The process uses a metal catalyst comprising osmium and a peroxy compound selected from the group consisting of peroxymonosulfuric acid and salts thereof to oxidatively cleave the oxidizable organic compound. In particular, the process enables aldehydes, carboxylic acids, esters, or ketones to be selectively produced from the corresponding mono-, 1,1-di-, 1,2-di-, tri-, or tetra-substituted olefins in a reaction that produces the result of ozonolysis but with fewer problems. The present invention further provides a process for oxidizing an aldehyde alone or with the osmium in an interactive solvent to produce an ester or carboxylic acid.

  • Patent number: 6559260
    Abstract: The present invention is for a new class of allyl urethane resin which can be cured with peroxide at high temperature alone or in combination with some accelerators. These allyl urethane resins can be sued alone or in combination with other free radically polymerizable materials such as allyl monomers and ligomers or (meth)acrylate monomers and oligomers. These new allyl urethane resins contain at least two allyl functional groups.

  • Patent number: 6541653
    Abstract: The process disclosed herein satisfies the need in the art for an industrially viable oxidative carbonylation catalytic system, and is capable of producing carbamates at a significantly higher rate than those processes reported in journal and patent literature. This reaction process takes place via a reaction mechanism that does not involve drastic conditions. Specifically, the catalytic system of the present invention employs Group VIII metal catalysts and/or copper-based catalysts with halide promoters to produce carbamates through heterogeneous oxidative carbonylation at atmospheric pressure and relatively non-drastic temperatures in a gas-solid carbonylation process.

  • Patent number: 6538094
    Abstract: The invention provides a process for preparing an allophanate-containing compound in the presence of a metal catalyst and a tertiary amine. In a preferred process, the tertiary amine compound also has a hydroxyl group. The hydroxyl group can react with the isocyanate functionality. Also disclosed is a process in which an allophanate-containing compound is prepared with copper acetate monohydrate as a catalyst. The allophanate-containing compound is used as a curing agent in coating compositions, particularly electrocoat coating compositions. The coating compositions are used to coat articles.

  • Patent number: 6515164
    Abstract: A low-monomer PU prepolymer containing free NCO groups which is obtained from polyhydric alcohols and diisocyanates differing in their reactivity and which is distinguished by the ratio of the NCO groups of the partly slower-reacting diisocyanate to the NCO groups of the faster-reacting diisocyanate. It is greater than 6:1. Nevertheless the prepolymer according to the invention cures more quickly than a known prepolymer predominantly containing fast-reacting NCO groups. In a preferred embodiment, TDI is used as the partly slower-reacting diisocyanate while MDI is used as the faster-reacting diisocyanate. The prepolymer is produced in two stages. The prepolymer according to the invention is suitable for bonding plastic articles, metals and paper, especially films. The accelerated absence of migration is particularly noticeable in this regard.
