  • Publication number: 20110110842
    Abstract: Systems and methods for the extraction of carbon nanotubes (CNTs) by continuous and/or batch processing are disclosed. Generally, a carbon nanotube material including carbon nanotubes (CNTs), carbon nanoparticles (CNPs), and carboxylated carbon (CC) is provided and agitated to produce a well-dispersed mixture. The well-dispersed mixture can be allowed to stand in a vessel having a lower end and an upper end. In some cases, the CNPs settle at the lower end. In some cases, at least some of the CNTs and CC are disposed at the upper end and can be removed in a dispersion, which can be pH adjusted and/or filtered to extract the CNTs from the CC.

  • Publication number: 20100316557
    Abstract: Systems and methods for the purification of carbon nanotubes (CNTs) by continuous liquid extraction are disclosed. Carbon nanotubes are introduced to a flow of liquid that enables the separation of CNTs from impurities due to differences in the dispersibility of the CNTs and the impurities within the liquid. Examples of such impurities may include amorphous carbon, graphitic nanoparticles, and metal containing nanoparticles. The continuous extraction process may be performed in one or more stages, where one or more of extraction parameters may be varied between the stages of the continuous extraction process in order to effect removal of selected impurities from the CNTs. The extraction parameters may include, but are not limited to, the extraction liquid, the flow rate of the extraction liquid, the agitation of the liquid, and the pH of the liquid, and may be varied, depending on the impurity to be removed from the CNTs.

    Abstract: A method of making (R)-N- 1-(3-methoxyphenyl)ethyl!-3-(2-chlorobenzene)propanamine which involves reducing the appropriate amidyl or iminyl precursor with an appropriate reducing agent. The appropriate amidyl or iminyl precursor is made from a synthesis involving the use of (R)-3-methoxy-.alpha.-methylbenzylamine. A method of condensing a nitrile with a primary or secondary amine to form an imine involves the reaction of a nitrile with diisobutylaluminum hydride; and then reacting the resultant compound with a primary or secondary amine to form the imine. The process is especially useful for producing enantiomerically pure chiral imines, and, ultimately, amines. Typical such imines have the formula: ##STR1## wherein R, R.sub.1, R.sub.2 and R.sub.3 are independently selected from the group consisting of hydrogen, substituted or unsubstituted alkyl, aryl and aralkyl.
