Abstract: Methods of forming a fertilizer composition having slow-release nitrogen compounds with a molten process are disclosed. The methods include mixing of a polyethylene wax with urea, formaldehyde, and one or more of an acid catalyst and emulsifier to form a molten methylene urea mixture. The contents of the molten methylene urea mixture react to form slow-release nitrogen compounds. Fertilizer compositions formed of, or including, the slow-release nitrogen compounds are also disclosed.

Abstract: A controlled-release fertilizer composition includes coated fertilizer particles having granules substantially encapsulated with a polyurethane coating layer formed from a polyol composition and an isocyanate curing agent. The polyurethane coating layers include inorganic particles. Methods of making and using the controlled-release fertilizer compositions are also disclosed.

Abstract: Reaction products and methods for making and using such reaction products are provided. For example, a reaction product comprising an adduct formed from urea, formaldehyde, and a urease inhibitor is described, which can be provided in various forms. For example, such a reaction product can be in the form of a solid or solution. Such a reaction product can also be combined with one or more additional components, including but not limited to, additional urease inhibitor and/or a nitrogen-based fertilizer composition.

Abstract: Epoxy compounds that are bisanhydrohexitol derivatives (i.e., isosorbide derivatives, isomannide derivatives, isoidide derivatives, or mixtures thereof) having two terminal oxirane groups are provided. Additionally, curable compositions that include these epoxy compounds, cured compositions prepared from the curable compositions, and articles containing the cured compositions are described. The cured compositions can be used, for example, as a structural adhesive or as a coating.

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.
