  • Publication number: 20150064092
    Abstract: Methods of producing fibrous solid carbon forests include reacting carbon oxides with gaseous reducing agents in the presence of a catalyst having a predetermined grain size to cause growth of fibrous solid carbon forests upon a surface of the metal. The fibrous solid carbon forests are substantially perpendicular to the surface of the metal thus creating the “forests”. A bi-modal forest composition of matter is described in which a primary distribution of fibrous solid carbon comprises the forest and a secondary distribution of fibrous solid carbon is entangled with the primary distribution. A reactor includes a catalyst, a means for facilitating the reduction of a carbon oxide to form solid carbon forests on a surface of the catalyst, and a means for removing the solid carbon forest from the surface of the metal catalyst.

  • Patent number: 8471051
    Abstract: One aspect of the present invention relates to a method for the transition metal (e.g., Cu(I)) mediated amidation of C—H bonds using electron-rich aliphatic azides. In certain embodiments, the methods are useful for the C—H insertion of nitrenes generated and stabilized by a ?-diketiminato metal catalyst. In certain embodiments, said nitrenes are generated from organoazides, or by oxidation of the corresponding amine. Another aspect of the present invention relates to olefin aziridination using said ?-diketiminato metal catalysts. In addition, the methods of the present invention include stereoselective C—H bond aminations and olefin aziridinatons. In certain embodiments, the methods are conducted in an aerobic environment. In certain embodiments, the present invention relates to the use of O2 as an oxidant, wherein water is the byproduct of oxidation; this fact avoids the generation of toxic byproducts and renders the methods atom economical.

  • Patent number: 6156915
    Abstract: A reactive and durable anti-static agent and the method of preparing the anti-static agent comprises: a compound with an amine group and a compound with an epoxide group added into the flask, stirred under the gradual raised temperature, reacted into an anti-static agent with a reactive functional group under proper temperature. The characteristics of the invention is that the reaction of preparing the anti-static agent is very active, and the preparing method is easy. With the reactive functional groups and polymer additives which enable the reaction in polymer, in addition to the endurance and a long lifetime, the surface property of the anti-static agent is improved. Therefore, the anti-static prepared according to the invention is broadly in use of industry.

  • Patent number: 5900508
    Abstract: A process for the preparation of amines by reacting an olefin with ammonia or a primary or secondary amine at a temperature of from 200 to 350.degree. C. and a pressure of from 100 to 300 bar in the presence of at least one zeolite having the specific structure type PSH-3, MCM-22 or SSZ-25, as identified by X-ray diffractogram, or mixtures of these zeolites. These specific catalysts are broadly identified as alumina zeolites and may be modified by ion exchange, doping with other metals, by dealumination to remove or replace the alumina content and by other well known after treatments such as calcination, acid-treatment and the like. Monoolefins are preferred reactants but di- and polyolefins also can be reacted with relatively high selectivity and less tendency toward polymerization.

  • 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.

  • Patent number: 5750790
    Abstract: The present invention relates to improved reductive amination catalysts useful in the production of alkyleneamine compositions having lower levels of cyclic components. Although typical reductive amination catalysts contain nickel or nickel-rhenium on carriers such as alumina, silica, silica-alumina and silica-titania, it has been discovered that by using carriers selected from the transitional aluminas, improvements are obtained in both selectivity to acyclic products and in activity of the catalysts.
