  • Publication number: 20100101455
    Abstract: The present invention relates in a first consideration to aldimines of formula (I). Said aldimines are particularly suitable as latent hardeners in curable compositions, particularly compositions comprising one or two-component isocyanate groups. Due to the presence of the reactive group, they can be converted to compounds of the formulas (X) and (XII) comprising aldimine groups, implementing a further consideration of the present invention. The aldimines, or the compounds comprising aldimine groups, can be used primarily in adhesive and sealant materials, but also in coatings, and can be produced easily from readily available source materials, and have good thermal stability. The tertiary amino group thereof has a surprisingly low alkalinity and can in some cases have a catalytic effect in chemical reaction systems.

  • Patent number: 6774270
    Abstract: A method of removing hexafluoropropylene dimers (“HFP dimers”), dimer hydrides and other oligomers from a fluid is described. The method comprises heating the fluid to isomerize the HFP dimers to the thermodynamic isomer, and contacting the fluid with a tertiary amine (or salts thereof) to form a hexafluoropropylene dimer—tertiary amine adduct. The method may further comprise the step of separating the dimer adducts from the reaction mixture.

  • Patent number: 6667392
    Abstract: This invention relates to colorants comprising a chromophore having a single azo acetoacetanilide moiety, wherein said moiety each have at least one poly(oxyalkylene) chain. Such colorants exhibit extremely good base stability and lightfastness, particularly when incoporated within certain media and/or on the surface of certain substrates. These poly(oxyalkylene) chains provide solubility in different solvents or resins thereby permitting the introduction of such excellent coloring chromophores within diverse media and/or or diverse substrates. Compositions and articles comprising such colorants are provided as are methods for producing such inventive colorants.

  • Patent number: 6664422
    Abstract: The present invention relates to a novel improved process and intermediates for the process of preparing the oxime intermediates of formula (II) wherein R1 is hydrogen, fluoro or chloro, and R2 is methyl, ethyl, methoxy, ethoxy, trifluoromethyl, trifluoromethoxy, cyano, fluoro, chloro or bromo. The novel process comprises diazotizing an aniline of formula (VI) reacting the resulting diazonium salt with isopropenylacetate of formula (X) and reacting the resulting ketone of formula (XI) with an organic nitrite in the presence of hydrogene chloride, and methylating the resulting ketooxime of formula (VIII) with a methylating agent and reacting the resulting O-methyl ketooxime of formula (IX) with hydroxylamine. The compounds of formula (II) are intermediates for highly active fungicides from the class of the strobilurins.

  • Patent number: 6569902
    Abstract: PBN (&agr;-phenyl-tert-butylnitrone), and its derivatives nitrone-based free radical traps, significantly reduce preneoplastic nodule development as well as inhibit hepatocellular carcinoma (HCC) formation at very low levels. The involvement of reactive oxygen species (ROS) in cancer development has been strongly implicated for many years. The involvement of ROS has been strongly implicated in cancer development is a model system where feeding a choline deficiency (CD) diet to rats leads to hepatocellular carcinoma (HCC) development. Administering PBN in the drinking water inhibits HCC formation. Preneoplastic nodule growth in the liver is significantly suppressed by administering PBN, or some of its natural metabolites, in the diet. The effectiveness of PBN in preventing HCC development in the CD liver model is considered due to its prevention of tumor development after the target cells have already been initiated, i.e. genetically changed into tumor cells.
