  • Publication number: 20150274621
    Abstract: The homogeneous hydrogenation of organic carbonyls, especially esters, under relatively mild conditions using iron hydrido-borohydride catalyst complexes having amino-phosphine pincer ligands. The catalyst and process are well-suited for catalyzing the hydrogenation of a wide variety of organic carbonyls, such as hydrogenation of fatty acid esters to alcohols. In particular embodiments, the process can be carried out in the absence of solvent.

  • Patent number: 7619119
    Abstract: Processes for converting glycerol to an amino alcohol product involving reacting glycerol with a metal catalyst to obtain hydroxyacetone, and reacting the hydroxyacetone with an amine compound to obtain an adduct that is then reduced using a reducing agent to obtain an amino alcohol product are described.

  • Patent number: 7378266
    Abstract: Improved processes for extracting polyhydroxyalkanoate from a biomass containing the polyhydroxyalkanoate including the steps of: combining the biomass containing the polyhydroxyalkanoate with a solvent selected from lower chain ketones, and mixtures thereof to form a biomass liquor wherein the biomass liquor comprises less than about 25% water; mixing the biomass liquor for from about 10 to about 300 minutes at a temperature in the range of from about 70° C. to about 120° C.; separating the polyhydroxyalkanoate from the biomass liquor to form a PHA-enriched liquor, wherein the separating occurs at a temperature of at least about 40° C.; mixing the PHA-enriched liquor with water to form precipitated polyhydroxyalkanoate and an impure solvent liquor, wherein the water is mixed with the PHA-enriched liquor in the ratio of from at least about 0.4-1 parts of water to one part solvent; and recovering the precipitated polyhydroxyalkanoate from the impure solvent liquor.

  • Patent number: 7118897
    Abstract: The invention relates to processes for extracting polyhydroxyalkanoate from a biomass, comprising admixing the biomass with an organic solvent for from 1 second to 15 minutes at a first temperature of from 5° C. below the melting point of the polyhydroxyalkanoate to 10° C. above the melting point of the polyhydroxyalkanoate and at a pressure of from 1 bar to 10 bar to provide a composition comprising the organic solvent and polyhydroxyalkanoate.

  • Patent number: 6617300
    Abstract: A granular bleach activator extrudate that has a size and shape that is within a relatively narrow distribution range. The bleach activator exhibits improved solubility, and reduced product separation when incorporated into a granular detergent composition. Also provided are granular detergent compositions comprising a detersive surfactant and the bleach activator extrudates. Methods for forming the extruded bleach activator particles are also provided.

  • Publication number: 20020058824
    Abstract: Process for preparing benzenesulfonate salts from an appropriately substituted acid chloride and a hydroxybenzenesulfonic acid is conducted in the absence of solvent, in a molar excess of acid chloride and in the presence of a phase transfer catalyst selected from quaternary ammonium and quaternary phosphonium salts and the target reaction product. The molar excess of the acid chloride is used to reduce the occurrence of gelation in the product.

  • Patent number: 5777165
    Abstract: N-alkyl polyhydroxy alkyl amines such as N-methyl glucamine having a Gardner Color of less than 1 are reacted with sources of fatty acyl groups such as methyl esters, anhydrides, and/or fatty acids that have greater than 98% transmittance at 460 nm in organic hydroxy solvents such as methanol to prepare N-alkyl polyhydroxy amine amides with good color. The N-alkyl polyhydroxyamines can be purified by crystallization, and/or subjected to reductive bleaching, to provide superior color. The reaction is preferably carried out at low temperature for short periods of time and with low catalyst levels to minimize formation of cyclic products. The resulting amide product can be further purified by treatment with anionic and cationic exchange resins to remove soap and amine impurities. The anionic ion exchange resin can be readily regenerated by acidifying it followed by washing with an organic solvent.
