  • Patent number: 8912358
    Abstract: A method for removing hydrocarbon impurities from an acetic acid production intermediate is disclosed. The method comprises extracting the intermediate with a hydrocarbon extracting agent. The extraction is preferably performed with the alkane distillation bottom stream which comprises methyl iodide, acetic acid, and hydrocarbon impurities. The extraction forms a light phase which comprises the hydrocarbon impurity and the extracting agent and a heavy phase which comprises methyl iodide and acetic acid. The extraction heavy phase is optionally recycled to the alkane distillation or to the carbonylation reaction.

  • Patent number: 7473746
    Abstract: A process for polymerizing unsaturated monomers is disclosed. The process comprises polymerizing, in the presence of a late transition metal catalyst (LTMC), a variety of unsaturated monomers which are traditionally, some of which are exclusively, made by free radical polymerizations. The LTMC polymerization provides the polymer with improved properties such as no free radical residue and narrow molecular weight distribution.

  • Patent number: 7087094
    Abstract: A drycleaning method is disclosed. In the method, a composition that comprises dipropylene glycol n-propyl ether (DPnP) and is essentially free of siloxanes or polysulfonic acids is used. The composition contains at least about 80 wt. % DPnP and up to about 15 wt. % of water. The method enables superior stain removal while avoiding excessive fabric shrinkage or soil redeposition.

  • Patent number: 6906136
    Abstract: A UV-curable composition is disclosed. The composition comprises a crosslinking agent, a hydroxyalkyl acrylate or methacrylate, and an acrylic polyol. The crosslinking agent is selected from the group consisting of multifunctional isocyanates, melamines, and silanes. The acrylic polyol comprises recurring units of an allylic alcohol. The composition can be irradiated to be solidified and then fully cured by the urethane, melamine, or silane reactions. Alternatively, the composition can be cured by the urethane, melamine, or silane reactions, and then fully cured by radiation. The invention provides low VOC but high performance coatings. More importantly, the invention provides a UV-curable system without the need for acrylated oligomers.
