    摘要： By the present invention, a surfactant system containing glyphosate has been created which can be used to yield formulations containing an ultra-high load of glyphosate, in which the glyphosate concentration is higher than previously possible in any agriculturally-acceptable formulation. Higher loadings are desirable to reduce shipping and container costs, as well as reduce wastes. The higher loading reduces storage requirements and allows the farmer to handle less volume of pesticide. The main advantage is that maximizing the loading minimizes the cost to deliver the active ingredient, which in turn maximizes economy in use of glyphosate.

    摘要： A process for preparing a catalyst by selecting an active catalyst and contacting the active catalyst with one or more fluids containing an organic solvent or mixture of organic solvents. In one embodiment, each organic solvent has a dielectric constant within a range of about 5 to about 55 when measured at a temperature of 20° C. to 25° C. The catalyst thus prepared may be used in a process for preparing maleic anhydride.

    摘要： A method for enhanced oil recovery contacts a gas and an alkylene carbonate with a subterranean formation. The gas may be selected from any gas that is suitable for injection into a subterranean formation and has properties that allow for enhanced recovery of petroleum from a subterranean formation. The alkylene carbonate may be cyclic, straight chained, or combinations thereof.

    摘要： This invention generally provides blocked isocyanate compositions and more specially blocked isocyanate compositions useful in aminoplastic resins, phenoplastic resins or latex resins for composite wood products, wherein the blocked isocyanate composition is obtained by adding alkylene carbonate to a blocked isocyanate (A), wherein the blocked isocyanate (A) is obtained by reacting a secondary amine (a1) with a reaction product (a2) of a polyfunctional isocyanate and a monofunctional hydroxyl containing compound, wherein the monofunctional hydroxyl containing compound is a polyethylene oxide polymer with terminal hydroxyl group, polyoxyethylene-polyoxypropylene monols or a mixture thereof, wherein the portion of blocked isocyanate (A) by weight percentage of the blocked isocyanate composition is between 50 and 90, preferably between 60 and 80. The compositions are stable at room temperature when mixed with active hydrogen containing compounds. The composition has low visicosity and after de-block has the potential to reduce free formaldehyde levels in formaldehyde containing resins.
