20080261814Alkoxylated Alkylamines/Alkyl Ether Amines With Peaked Distribution - The present invention generally relates to a process for preparing the alkoxylated alkylamines and/or alkyl ether amines. The process consists of three stages, and utilizes an alkali catalyst. The alkoxylated alkyl amines and alkoxylated alkyl ether amines prepared by the process possess the peaked distribution and contain less hazardous by-product.10-23-2008
20100056376ALKOXYLATED ALKYLAMINES/ALKYL ETHER AMINES WITH PEAKED DISTRIBUTION - The present invention relates to processes for preparation of alkoxylated alkyl amines or alkoxylated alkyl ether amines with peaked distribution, surfactants comprising alkoxylated alkyl amines or alkoxylated alkyl ether amines with peaked distribution, and stable herbicidal formulations comprising alkoxylated alkyl amines or alkoxylated alkyl ether amines with peaked distribution.03-04-2010

Patent application numberDescriptionPublished
20090011515Control of N-(Phosphonomethyl)Iminodiacetic Acid Conversion in Manufacture of Glyphosate - This invention relates to the preparation of N-(phosphonomethyl)glycine (“glyphosate”) from N-(phosphonomethyl)iminodiacetic acid (“PMIDA”), and more particularly to methods for control of the conversion of PMIDA, for the identification of reaction end points relating to PMIDA conversion and the preparation of glyphosate products having controlled PMIDA content.01-08-2009
20100160162HERBICIDE FORMULATIONS CONTAINING AN ETHERAMINE AND ALKYLAMINE ALKOXYLATE SURFACTANT SYSTEM - The present invention generally relates to herbicidal compositions comprising a herbicide, an etheramine alkoxylate surfactant, an alkylamine alkoxylate surfactant having a high degree of alkoxylation and compatibilizer comprising, in some embodiments, an alkylamine alkoxylate surfactant having a low degree of alkoxylation or an alkylpolyglucoside surfactant. The herbicidal compositions are herbicidally efficacious and cause low eye irritation and low crop injury.06-24-2010
20100234228NOVEL SURFACTANTS AND FORMULATIONS - A herbicidal composition is provided comprising an aqueous solution of N-phosphonomethylglycine, predominantly in the form of the potassium salt thereof, at a concentration of at least 300 g a.e./l of the composition; and a surfactant component in solution or stable suspension, emulsion, or dispersion in the water, comprising one or more surfactants in a total amount of about 20 to about 300 g/l of the composition, wherein the composition has a viscosity of less than about 250 centipoise at 0° C. or a Gardner color value less than 10.09-16-2010
20100248963Encapsulation of Herbicides to Reduce Crop Injury - Methods of reducing injury to crop foliage and achieving weed control using encapsulated acetamide herbicides are described. Herbicidal microcapsules comprising herbicide core material and a shell wall encapsulating the core material are also described. The microcapsules provide reduced crop injury through controlled herbicide release.09-30-2010
20110034332Herbicidal compositions containing N-phosphonomethyl glycine and an auxin herbicide - Herbicidal compositions are provided which cause rapid symptomology while delivering long term control of regrowth of plants. The herbicidal concentrate compositions comprise N-phosphonomethylglycine or a herbicidal derivative thereof, an auxin herbicide or a herbicidal derivative thereof, and at least one surfactant. Also provided is a method for killing or controlling the growth of certain plants by contacting the foliage of the plants with the diluted concentrate composition.02-10-2011
20110097810CONTROL OF N-(PHOSPHONOMETHYL)IMINODIACETIC ACID CONVERSION IN MANUFACTURE OF GLYPHOSATE - This invention relates to the preparation of N-(phosphonomethyl)glycine (“glyphosate”) from N-(phosphonomethyl)iminodiacetic acid (“PMIDA”), and more particularly to methods for control of the conversion of PMIDA, for the identification of reaction end points relating to PMIDA conversion and the preparation of glyphosate products having controlled PMIDA content.04-28-2011
