  • Patent number: 7695706
    Abstract: Provided are a method of efficiently procuding fullerene into which a OH group or a SO3H group is introduced, such as fullerenol, or a derivative thereof, the fullerene and its derivative being preferable as a proton conductor, and a novel and usable proton conductor obtained by the method. Further, provided is an electrochemical device using the proton conductor such as a fuel cell or the like. In the producing method of the fullerene derivative, halogated fullerene, which is obtained through halogating a fullerene molecule is used as a precursor, the fullerene derivative is produced through introducing one or more proton dissociative group into at least one carbon atom of a fullerene molecule. Moreover, in a producing method of a polymerized fullerene derivative, a plurality of fullerene derivatives are bonded to one another by an aromatic group of an aromatic compound through reacting the plurality of fullerene derivatives with the aromatic compound.

  • Patent number: 7202377
    Abstract: The present invention relates to a method of saturating ethylene-containing gases with acetic acid before they are fed into a vinyl acetate reactor, in which the acetic acid recovered in the vinyl acetate process is introduced into a column having a countercurrent stripping section and a rectification section and ethylene-containing gas is supplied via the bottom, wherein the liquid taken off at the bottom of the column is divided into two substreams and one substream is pumped back into the column with maintenance of a minimum pumped circulation required for sufficient saturation with acetic acid.
