  • Patent number: 8231853
    Abstract: A method for producing of ultra-dispersed carbon comprises the steps of introducing gaseous methane and chlorine into passageways (3 and 4) of a burner (2) communicating with a chamber (1) of a reactor, combusting the mixture of methane and chlorine resulting in the formation of a diffusion flame, depositing products of a process of oxidative coupling of methane, separating a suspension containing solid carbon particles, and extracting a desired product. The greater part of the methane stream is fed to the outer boundary of the flame through a branch pipe (6) provided within the reactor chamber. Internal walls of the reactor chamber (1) in the combustion zone of the diffusion flame are washed by means of water stream. The desired product is extracted from the crude product through thermal processing of the solid particles suspension. Utilization of the method essentially increases the mono-dispersed carbon yield in the process of oxidative coupling of methane.

  • Publication number: 20100155221
    Abstract: A method for the production of fluorinated carbon nanostructures such as carbon black is disclosed, wherein a plasma is generated in a plasma chamber and a fluorocarbon, or a fluorocarbon containing mixture, is supplied to the plasma to convert at least some of the fluorocarbon into a fluorinated carbon material. Direct pyrolysis of a fluorocarbon, or a mixture containing this, provides a one-step method for producing fluorinated carbon nanostructures with a formula CFx, where 0.06<x<0.15, the particles having a relatively narrow spread of diameters, and exhibiting excellent hydrophobicity.

  • Publication number: 20080149472
    Abstract: A process is disclosed for increasing the fluorine content of at least one compound selected from halohydrocarbons and hydrocarbons. The process involves (a) directing light from a light source through the wall of a reactor to interact with reactants comprising chlorine and said at least one compound in said reactor, thereby producing a halogenated hydrocarbon having increased chlorine content by photochlorination, and (b) reacting said halogenated hydrocarbon produced by the photochlorination in (a) with HF; and is characterized by the light directed through the reactor wall being directed through a poly(perhaloolefin) polymer.

  • Patent number: 6702929
    Abstract: In the synthesis of 1,1,1,3,3-pentafluorobutane (R-365mfc), a mixture of R-365mfc and the impurity 1,1,1,3-tetrafluoro-2-butene (R-1354mzy) is purified and R-1354mzy is removed from the mixture by contacting the mixture with 1-5 mols of chlorine for each mol of R-1354mzy in the presence of ultraviolet light having a wavelength between about 300 to 400 nm which provides at least 0.02 watts-hour/kg of the mixture. The R-1354mzy is reduced to below 10 wt. ppm as it is converted to 2,3-dichloro-1,1,1,3-tetrafluorobutane (R-354) or other butane containing more chlorine and having a higher boiling point than R-365mfc. The butane(s) may be separated more easily from R-365mfc. The photochlorination is effected in a manner such that at least about 96 weight percent of the starting amount of R-365mfc is maintained in the mixture.

  • Patent number: 6551469
    Abstract: A process for preparing 1-chloro-1,1,3,3,3-pentafluoropropane, CF3CH2CF2Cl, comprising contacting in a reaction zone in the substantial absence of oxygen, reactants comprising chlorine and 1,1,1,3,3-pentafluoropropane, CF3CH2CHF2 (also referred to as HFC-245fa), and subjecting the reactants to actinic radiation, such as UV light at about 2,000 to 4,000 Angstroms, wherein: (1) inert gas is present at a concentration equal to or less than about 5 wt. % of the total weight of reactants; (2) the molar ratio of chlorine to CF3CH2CHF2 is from about 0.2:1 to about 1.5:1; and (3) the concentration of chlorinated product produced having greater than one chlorine present in the molecule is less than or equal to about 10 wt. %.

  • Patent number: 6245200
    Abstract: A method of photo-oxidizing a hydrocarbon compound is provided by dispersing MoS2 nanoclusters in a solvent containing a hydrocarbon compound contaminant to form a stable solution mixture and irradiating the mixture to photo-oxide the hydrocarbon compound. Hydrocarbon compounds of interest include aromatic hydrocarbon and chlorinated hydrocarbons. MoS2 nanoclusters with an average diameter less than approximately 10 nanometers are shown to be effective in decomposing potentially toxic aromatic and chlorinated hydrocarbons, such as phenol, pentachlorophenol, chlorinated biphenols, and chloroform, into relatively non-toxic compounds. The irradiation can occur by exposing the MoS2 nanoclusters and hydrocarbon compound mixture with visible light. The MoS2 nanoclusters can be introduced to the toxic hydrocarbons as either a MoS2 solution or deposited on a support material.
