    摘要: The present invention concerns a method for separation of pyridine and/or pyridine derivatives from aqueous solutions by extraction with pressurized carbon dioxide. The invention is based on the insight that carbon dioxide is a weak acid and pyridine and/or pyridine derivatives are weak bases. The acid-base interaction between the solute and the solvent makes carbon dioxide a particularly suitable solvent for the extraction of certain weak bases from aqueous solutions.

    摘要: A method for forming an electrically conductive polymeric surface on a solid polymeric substrate (S) comprises the following successive steps: 1) treatment of the solid polymeric substrate (S) in a pressure reactor (1) with a first supercritical or liquid carbon dioxide phase containing a monomer to cause the monomer to enter the structure of the polymeric substrate,2) removal of the first supercritical or liquid carbon dioxide phase from the reactor (1), together with possible residues of the monomer 3) feeding of a second supercritical or liquid carbon dioxide phase containing an oxidative agent into the reactor (1) into contact with the substrate (S) that has remained in the reactor, and 4) performing in-situ oxidative polymerization of the monomer in the polymeric substrate with the help of the oxidative agent to form an electrically conductive polymer surface on the polymeric substrate (S), 5) removal of the second supercritical or liquid carbon dioxide phase from the reactor.

    摘要: This invention concerns a method for catalytic hydrogenation of aromatic nitrocompounds to aromatic amines by applying a supercritical or near-critical state solvent. The aromatic nitro compound, hydrogen gas and the solvent are mixed together under elevated pressure and temperature, so that a homogenous mixture which is in supercritical or near-critical state is formed. The resulting mixture is brought into contact with the catalyst and the reaction product is formed. The method has applicability to industrial processes for producing aromatic amines.

    摘要: The present invention is related to the chemistry of forest industry. In particular, the invention is related to the acidification of tall oil soap and to a process to fractionate tall oil soap. According to the patented method, tall oil soap is contacted with high pressure carbon dioxide, and simultaneously, the formed brine containing aqueous-and tall oil phases are separated. By this method the tall oil soap can be acidulated almost completely, and there is no need to add sulfuric acid. High quality tall oil can be produced by this method.
