  • Patent number: 7923582
    Abstract: The present invention features a chemoselective ligation reaction that can be carried out under physiological conditions. In general, the invention involves condensation of a specifically engineered phosphine, which can provide for formation of an amide bond between the two reactive partners resulting in a final product comprising a phosphine moiety, or which can be engineered to comprise a cleavable linker so that a substituent of the phosphine is transferred to the azide, releasing an oxidized phosphine byproduct and producing a native amide bond in the final product. The selectivity of the reaction and its compatibility with aqueous environments provides for its application in vivo (e.g., on the cell surface or intracellularly) and in vitro (e.g., synthesis of peptides and other polymers, production of modified (e.g., labeled) amino acids).

  • Patent number: 7566807
    Abstract: The present invention provides BZPA products with improved flowability and two methods of producing such BZPA products. Both methods successfully produce BZPA products that are not prone to agglomerate upon storage, and thus the flowability of such BZPA products does not degrade over time. The first method includes mechanically forming the BZPA crystals into large compacted pellets or briquettes without the introduction of any additives or binders. The compacted pellets are large enough that the physical and chemical effects that occur on the surface of small crystal particles are eliminated or minimized, but small enough that the BZPA can be easily handled and used in commercial applications. The second method includes adding a substantially inert anti-caking agent to the BZPA crystals to minimize or retard their tendency to agglomerate. The preferred anti-caking agent is silicon dioxide (SiO2), which is blended with the BZPA crystals in small amounts.

  • Publication number: 20080146820
    Abstract: This invention relates to surfactant compositions comprising a phosphate fluorosurfactant and a siloxane surfactant wherein the surfactant composition's ability to lower equilibrium surface tension exceeds that of either the phosphate fluorosurfactant or the siloxane surfactant. Because of the synergistic interaction of the phosphate fluorosurfactant and the siloxane surfactant, it is possible to use only small amounts of the more expensive fluorosurfactant in the surfactant composition of the present invention while preserving or improving the ability to lower the equilibrium surface tension of a liquid, such as water.

  • Patent number: 7351868
    Abstract: A process for the minimization of phosphonium ion ligand degradation products formed during reaction of a polyunsaturated olefin or an unconjugated functionalized olefin in the presence of a transition metal-triorganophosphine ligand complex catalyst to form as a product, by-product, or intermediate product a conjugated functionalized olefin having a carbon-carbon double bond conjugated to an a-electronwithdrawing group, such as, an a,?-unsaturated aldehyde, ketone, ester, acid, or nitrile. The minimization process involves conducting the reaction under selected conditions of conversion, temperature, pressure, or a combination thereof; and/or by selecting a triorganophosphine ligand with a specified steric and/or electronic property.
