    摘要: An electrochemical process for the production of benzanthrone by reaction of anthraquinone as, starting material, with glycerol, which process comprises reducing anthraquinone, which may additionally contain electronegative substituents, at the cathode in an electrolytic cell in acid medium, and simultaneously cyclizing the reduced semiquinone form with glycerol to produce the corresponding benzanthrone. The novel process affords numerous advantages compared with chemical reduction methods.

    摘要: An electrochemical process for the preparation of benzanthrones and planar, polycyclic aromatic oxygen-containing compounds is described. The process is carried out in an acid medium in an electrolytic cell which is separated by a diaphragm into a cathode compartment and an anode compartment.In the cathode compartment, anthraquinone or an anthraquinone derivative is reduced electrolytically to oxanthrone and the latter is reacted with glycerol to give the corresponding benzanthrone.In the anode compartment, a transition metal ion is simultaneously converted electrolytically from a lower oxidation stage into the next higher oxidation stage. The metal ion of higher valency is then used in the anolyte as an oxidizing agent by means of which the corresponding oxygen-containing compounds are obtained, starting from planar, polycyclic aromatic compounds.

    摘要: A gearing is described for locks of panic doors. The gearing has a first gearing part (17)which is rotatable around a first axis (17a) and can be connected with an actuating member (18) for a lock nut or the like, and a second gearing part (28) which is rotatable around a second axis perpendicular to the first axis and is connected with a handle (1). One of the gear parts is provided with a driver pin (24) arranged parallel to and at a distance from the first axis and the other gearing part is provided with a guide part cooperating with the latter for the purpose of converting the rotating movement of the handle (1) into a rotating movement of the actuating member (18).
