  • Publication number: 20240158358
    Abstract: Disclosed herein are methods and processes of preparing 3-amino-(C3-6)-alkan-1-ol, including optically active 3-amino-(C3-6)-alkan-1-ol (e.g., optically active 3-amino-1-butanol such as (R)-3-amino-1-butanol). The 3-amino-(C3-6)-alkan-1-ol may be optionally substituted at the 1-position, e.g., with OH, alkoxy, O-acetyl, or silyl groups, among others. The processes include contacting a 1-nitro-(C1-4)-alkane with a vinyl source or an acetylene source in the presence of a base and a dehydrating agent to provide 3-(C0-3)-alkyl-2-isoxazoline; and/or contacting the 3-(C0-3)-alkyl-2-isoxazoline with hydrogen and a hydrogenation catalyst to provide 3-amino-(C3-6)-alkan-1-ol.

  • Patent number: 8410185
    Abstract: A porous polymer, poly-9,9?-spirobifluorene and its derivatives for storage of H2 are prepared through a chemical synthesis method. The porous polymers have high specific surface area and narrow pore size distribution. Hydrogen uptake measurements conducted for these polymers determined a higher hydrogen storage capacity at the ambient temperature over that of the benchmark materials. The method of preparing such polymers, includes oxidatively activating solids by CO2/steam oxidation and supercritical water treatment.
