    Abstract: Provided herein are polyamine precursors useful in the manufacture of epoxy resins. Use of a polyamine precursor according to the invention provides an epoxy resin formulation having an increased working time over prior art amines used for curing epoxies. Increased working times translate to the ability to manufacture composites which could not be made using conventional epoxy curing agents, such as composite blades for wind-driven turbines. Such polyamines are also useful in polyurea formulations for lengthening reaction time, thus allowing more flow of applied polyurea coatings prior to gellation.

  • Patent number: 6583182
    Abstract: This invention involves synthesis and use of a class of compounds with chelation affinity and selectivity for first transition series elements. Administration of the free or conjugated compound, or physiological salts of the free or conjugated compound, results in decrease in the in vivo bioavailability of first transition series elements and/or removal from the body of first transition series elements and elements with similar chemical properties. These characteristics make such compounds useful in the management of diseases associated with a bodily excess of first transition series elements and elements with similar chemical properties. This invention demonstrates that such compounds inhibit mammalian, bacterial, and fungal cell replication and are therefore useful in the treatment of neoplasia, infection, inflammation, immune reponse, and in termination of pregnancy.

  • Patent number: 6458999
    Abstract: The present invention is related to a series of derivatives of novel ether diamine compounds prepared by the cyanobutylation reaction of an alcohol having 3 to 22 carbon atoms with 2-pentenenitrile to form a branched alkyl ether nitrile. The etheraminonitriles formed by the process are hydrogenated to form alkylether amines. The resulting product can be reacted with 2-pentenenitrile and or acrylonitrile and in a subsequent step, hydrogenated to yield a diamine. Specifically, the present invention deals with two types of tertiary amines one made by the reaction of novel ether diamines compounds with ethylene oxide, propylene oxide or butylene oxide or mixtures thereof, producing alkoxylated tertiary amines and the other made by the reaction of novel ether amine compounds with formaldehyde and hydrogen producing methylated tertiary amines. The invention also disclosed novel amine oxides, and quaternary compounds made from said tertiary amines.

  • Patent number: 6458837
    Abstract: The invention discloses stable diesters of chelating agents of divalent metal ions, processes for their preparation and pharmaceutical compositions thereof. Most preferred compounds according to the present invention are stable lipophilic diesters comprising a covalent conjugate of a BAPTA and a pharmaceutically acceptable alcohol. The diesters are useful in a method for treating a condition or disease related to an excess of divalent metal ions, and in particular for the treatment of a condition or disease related to elevated levels of intracellular calcium ions, such as in brain or cardiac ischemia, stroke, epilepsy, Alzheimer's disease or cardiac arrhythmia and in open heart surgery.

  • Patent number: 6060625
    Abstract: A process for the alkoxylation of a polyetheramine to form an etheramine alkoxylate. In the process, a polyetheramine is reacted with an alkylene oxide in the presence of an alcohol to form the etheramine alkoxylate. The alcohol serves as a catalyst to allow the reaction proceed at a heightened temperature as compared to the reaction in the absence of alcohol, while at the same time limiting the amount of glycol by-product production which would otherwise typically form when higher polyetheramines are to be alkoxylated. The alcohol may be, for instance, ethanol or methanol.
