摘要： The present invention is based upon the discovery that nontitanyl oxalates can enhance the catalytic functionality of titanyl oxalate catalysts. This invention provides a novel catalytic composition containing a titanyl oxalate catalyst and a metallic oxalate catalyst enhancer and optionally containing a metallic cocatalyst such as an antimony based catalyst. A synergistic relationship has been discovered between titanyl oxalate catalyst and the catalyst enhancer. A synergistic relationship has also been discovered between the titanyl oxalate catalyst, catalyst enhancer and a metallic cocatalyst such as antimony oxide or antimony triacetate. Also provided is an improved process of producing polyester by the polycondensation of polyester forming reactants in the presence of a catalytically effective amount of a polycondensation catalyst, wherein the improvement comprises utilizing, as the polycondensation catalyst, the novel catalyst composition containing a titanyl oxalate such as lithium titanyl oxalate and a catalyst enhancer such as a nontitanyl metallic oxalate like lithium oxalate and optionally containing a metallic catalyst such as antimony oxide or antimony triacetate. The improved process produces an improved polyester having lower acetaldehyde numbers and good color. The titanyl oxalate/catalyst enhancer composition can be used as a polycondensation catalyst in combination with other catalysts to achieve synergistic catalytic activity. Preferred is a combination of lithium or potassium titanyl oxalate, Li2 or K2TiO(C2O4)2, lithium or potassium oxalate, Li2 or K2(C2O4)2 with antimony oxide or antimony triacetate or antimony trisglycoxide.

摘要： Provided are dispersions which comprise more than about (40) percent by weight of an organic peroxide which is normally solid, an effective dispersing amount of a pharmaceutically acceptable dispersing agent and water. The water and about (40) percent or more peroxide forms a paste. Addition of the dispersing agent/surfactant to a non-flowing organic paste resulted in the formation of a shear thinning aqueous dispersion. The aqueous dispersions can also contain optional components such as thickening agents and anionic emulsifiers.

摘要： A method for using a fracture fluid in forming subterranean fractures includes delaying degradation of a polymer in a fracture fluid when the fracture fluid comprises a breaker by combining at least one radical scavenger with the fracture fluid. The mixture for use in a fracture fluid comprises a radical scavenger and a breaker. A method of fracturing a subterranean formation may include providing a fracture fluid comprising a proppant, a polymer, and a breaker and adding a radical scavenger to the fracture fluid. The fracture fluid is supplied to a desired location in the subterranean formation to form at least one fracture where the viscosity of the fracture fluid is maintained. The breaker is then allowed to degrade the polymer and reduce the viscosity of the fracture fluid at a specific time or temperature.
