  • Process for preparing rifaximin ?
    Patent number: 9708343
    Abstract: The present invention relates to a process for obtaining rifaximin ? comprising the following steps: a) reacting rifamycin O with 2-amino-4-picoline in the presence of a solvent mixture comprising water and a solvent selected from methyl isobutylketone, ethylacetate and a water soluble solvent; b) obtaining a rifaximin solution by removing the aqueous phase; c) obtaining rifaximin ? from the rifaximin solution, wherein when the solvent is a water soluble solvent, either methyl isobutylketone or ethylacetate is further added in step a). In another aspect the process of the invention relates to a process for obtaining the crystalline form ? of rifaximin comprising the following steps: i) contacting rifaximin or a rifaximin solution with exclusively ethylacetate, ii) obtaining the rifaximin in crystalline form ? by removing ethylacetate.

  • Electronic platform comprising an ABOtype crystal and graphene, method for its manufacture and chip comprising the same
    Patent number: 9548435
    Abstract: An electronic platform comprising a substrate made of a ABO3 crystal (2) and at least one layer of a two-dimensional conducting sheet of carbon atoms (1) of a thickness between one and four atoms, characterized in that the conducting layer(s) is (are) placed on top of a face of the crystal whose orthogonal axis is at an angle up to 35° of the crystal's spontaneous polarization or c-axis. The invention achieves a sheet resistance lower than 1 ?/square at temperatures higher than 77K.
