  • Patent number: 8986400
    Abstract: The present disclosure relates to a method of converting glycerol into organic reaction products. The method may include mixing glycerol with a monohydric alcohol. The mixture of glycerol and monohydric alcohol is then reacted in the presence of a heterogeneous nano-structured catalyst, wherein the monohydric alcohol is present at subcritical/supercritical temperatures and pressures. This converts the glycerol into one or more reaction products, wherein the reaction products include an oxygenated organic reaction product. Ninety percent or greater of the glycerol is converted.

    Abstract: A method for functionalizing the wall of single-wall or multi-wall carbon nanotubes involves the use of acyl peroxides to generate carbon-centered free radicals. The method allows for the chemical attachment of a variety of functional groups to the wall or end cap of carbon nanotubes through covalent carbon bonds without destroying the wall or endcap structure of the nanotube. Carbon-centered radicals generated from acyl peroxides can have terminal functional groups that provide sites for further reaction with other compounds. Organic groups with terminal carboxylic acid functionality can be converted to an acyl chloride and further reacted with an amine to form an amide or with a diamine to form an amide with terminal amine. The reactive functional groups attached to the nanotubes provide improved solvent dispersibility and provide reaction sites for monomers for incorporation in polymer structures. The nanotubes can also be functionalized by generating free radicals from organic sulfoxides.

    Abstract: A process for preparing polyether polyols includes a precipitation step, a recrystallization step, and a reaction step. In the precipitation step, a multimetal cyanide compound is precipitated by reaction of a metal salt with a cyanometalate compound. In the recrystallization step, the multimetal cyanide compound precipitated above is recrystallized by adding further metal salt and/or further cyanometalate compound. The recrystallization forms a multimetal cyanide catalyst compound. In the reaction step, an initiator and one or more alkylene oxide are reacted in the presence of the multimetal cyanide catalyst compound.

  • Patent number: 6906230
    Abstract: The invention describes a process for the preparation of surfactant alcohols and surfactant alcohol ethers which are, inter alia, highly suitable as surfactants or for the preparation of surfactants. The process, starting from olefin mixtures having a defined minimum content of linear hexenes, gives mixtures having a predominant fraction of branched dodecenes, which are subsequently derivatized to give surfactant alcohols and then optionally alkoxylated. The surfactant alcohol mixture obtained in the process has a degree of branching of from 2.0 to 3.0 and in particular exhibits advantageous properties as regards ecotoxicity and biodegradability. A description is also given of the use of the surfactant alcohols and surfactant alcohol ethers as surfactants by glycosidation or polyglycosidation, sulfation or phosphation.

  • Patent number: 6858580
    Abstract: A non-polydispersed mixture of conjugates in which each conjugate in the mixture comprises a drug coupled to an oligomer that includes a polyalkylene glycol moiety is disclosed. The mixture may exhibit higher in vivo activity than a polydispersed mixture of similar conjugates. The mixture may be more effective at surviving an in vitro model of intestinal digestion than polydispersed mixtures of similar conjugates. The mixture may result in less inter-subject variability than polydispersed mixtures of similar conjugates.

  • Patent number: 6858761
    Abstract: The present invention provides a process and its utilization in a process comprising the step of carrying out an addition reaction of an alkylene oxide to an addition-receiving substance in the presence of a resin catalyst, thereby producing the addition reaction product, when the resin catalyst as used for the reaction is persevered so as to recycle it after it is recovered, the unreacted alkylene oxide remaining in the resin catalyst can be prevented from polymerizing and solidifying during the preservation, and the resin catalyst accordingly can be preserved stably for a long time. The resin catalyst as recovered after it is used for the reaction may be preserved under any of the following conditions: 1) at a low temperature of not higher than 40° C.

  • Patent number: 6821308
    Abstract: Oleophilic polyoxyalkylene monoethers having reduced water affinity are disclosed. The monoethers have a hydrocarbyl residue, a polyoxyalkylene moiety, and a hydroxyl end group. The monoethers contain less than about 6 mole percent of alkoxylated unsaturates, and preferably less than about 5 mole percent of polyoxyalkylene diols. The monoethers offer substantial advantages for fuel compositions, particularly reduced water affinity. By using deposit-control additives based on the monoethers, formulators can offer better fuels for cleaner engines.
