  • Publication number: 20130217897
    Abstract: An oxidation catalyst comprising vanadium, phosphorus, and oxygen having average vanadium valence less than about 4.10, and a method of preparing such catalyst, is provided. The catalyst has side crush strength of at least about 5 lbs. and improved yield of maleic anhydride from n-butane between about 1% and about 6% absolute. The catalyst is formed by exposing a conventional active VPO catalyst having average vanadium valence between about 4.10 and about 4.40 to an organic solvent having a dielectric constant between about 5 and about 55 under conditions that facilitate an oxidation-reduction reaction, reducing the valence of the vanadium below 4.10.

  • Publication number: 20130172589
    Abstract: A surface active agent comprising an arylated methyl ester of a fatty acid, or mixture of fatty acids, derived from biodiesel or a triglyceride source is disclosed. The fatty acid mixture is condensed to methyl esters and alkylated with aromatic substituents under Friedel-Crafts conditions. The alkylated methyl esters may be alkoxylated using a catalyst derived from fatty acids, alkaline earth salts, and strong acids. The resulting nonionic surfactant may also be sulfonated to produce one class of anionic surfactants. The alkylated methyl esters may also be directly sulfonated to produce another class of anionic surfactants.

  • Patent number: 8435927
    Abstract: 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.
