Abstract: An improved nitrification inhibitor composition comprising UFP particles and a nitrification inhibitor, and optionally other components, is used as an additive for liquid and solid fertilizers, typically containing urea. The nitrification inhibitor particularly can be nitrapyrin and/or DMPP. Methods of making the compositions and their use are also disclosed.

Abstract: This invention relates to a urea granule with a nitrogen stabilizer and carrier system substantially homogenously dispersed throughout the granule thickness. Several methods are disclosed to make the urea granule, including prilling, fluidized bed, and drum granulation. The carrier system can comprise any solvent system that is both: (1) stable at urea melt temperatures of ˜120° C.; (2) able to solvate the nitrogen stabilizer system; and (3) miscible in molten urea. Such carrier systems can be blends of NMP and a glycol (e.g. propylene glycol). The nitrogen stabilizer can include a urease inhibitor, such as NBPT, where the NBPT purity can be between 90 and 99%. The nitrogen stabilizer can also include a nitrification inhibitor, such as DCD.

Abstract: Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants, for example in the beneficiation of value materials (e.g., bitumen, coal, or kaolin clay) to remove impurities such as sand. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water.

These resins are especially useful as froth flotation depressants in the separation of bitumen from sand and/or clay or in the beneficiation of clay (e.g., kaolin clay) from an impure clay-containing ore. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water.

Abstract: The present invention relates to formaldehyde scavenger treatments for porous fiberglass material having formaldehyde emitting binders thereon. The invention also relates to methods of making porous fiberglass material having reduced formaldehyde emissions.

Abstract: Modified resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These modified resins are especially useful as froth flotation depressants in the beneficiation of many types of materials (e.g., mineral and metal ores), including the beneficiation of impure coal comprising clay impurities, as well as in the separation of valuable bitumen from solid contaminants such as sand. The modified resins are also useful for treating aqueous liquid suspensions to facilitate the removal of solid particulates, as well as the removal of metallic ions in the purification of water. The modified resins comprise a base resin that is modified with a coupling agent, which is highly selective for binding to solid contaminants and especially siliceous materials such as sand or clay.

Abstract: A method for reducing formaldehyde emissions from articles prepared from, or which otherwise comprise formaldehyde-emitting compositions, such as formaldehyde-containing resins, is described. The method relates especially to a method for reducing formaldehyde emissions from products such as cellulose laminates, permanent press (wrinkle-free) textiles, floral foams and ceiling or acoustical tiles, which involves isolating the article in an enclosed space with a formaldehyde scavenger, particularly a formaldehyde scavenger carried by a substrate.

Abstract: An aqueous, formaldehyde-free binder composition comprising a modified copolymer of maleic anhydride and a vinyl aromatic compound such as styrene, the copolymer being modified by reaction with a primary alkanolamine, such as monoethanolamine (MEA), to produce a modified copolymer that is self-curing and cures as a consequence of cross-linking, esterification reactions between pendant carboxyls and hydroxyl groups on the solubilized (hydrolyzed) modified copolymer chains; the invention also relates to the corresponding method of using the binder composition for making fiber products, especially fiberglass insulation.
