The solvent systems provided good solubility of the urease inhibitor as well as at least one of improved stability, lower flammability, lower toxicity, improved cold temperature storage, improved handling, improved adsorption onto and/or solubility with solid media such as urea. Methods of making and using the compositions are also provided. | 02-20-2014 |
20140047883 | Liquid Compositions Containing Urease Inhibitors and Glycol Alkyl Ethers and Methods of Making a Use Thereof - The present invention provides improved solvent systems for the preparation of liquid formulations of urease or nitrification inhibitors, specifically NBPT, comprising alkylene glycol alkyl ethers. The solvent systems provided good solubility of the urease inhibitor as well as at least one of improved stability, lower flammability, lower toxicity, improved cold temperature storage, improved handling, improved adsorption onto and/or solubility with solid media such as UFP or urea. Methods of making and using the compositions are also provided. | 02-20-2014 |
20140047884 | Compositions of Substantially Spherical Particles and Methods of Making Thereof - An improved composition comprising substantial spherical UFP particles and an active agent, such as NBPT, and optionally other components is used as an additive for liquid and solid fertilizers, typically containing urea. Methods of making the compositions and their use are also disclosed. | 02-20-2014 |
20140301921 | AMINE-ALDEHYDE RESINS AND USES THEREOF IN SEPARATION PROCESSES - 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. | 10-09-2014 |
