Description

  

  Verfahren zur Herstellung von     methyl-p-tolylearbinol-eamphersaurem    Natrium.    Es ist bekannt, dass das ätherische 01 der       'remoe-Lawak-Droge    und insbesondere das  zu etwa 5 % darin enthaltene     Methyl-p-tolyl-          carbinol        gallesekretionssteigernde    Wirkun  gen besitzt. Der therapeutischen Anwendung  dieses Alkohols steht aber seine Wasser  unlöslichkeit entgegen, die insbesondere eine       parenterale    Anwendung unmöglich macht.  



  Es     wurde    nun gefunden, dass man eine  neue, leicht wasserlösliche Verbindung des       3Iethyl-p-tolylcarbinols    dadurch herstellen  kann, dass man     Natrium-methyl-p-tolylearbi-          nolat    mit     Camphersäureanhydrid    in einem  organischen Lösungsmittel umsetzt. Das Na  trium -     methyl    - p -     tolylcarbinolat    kann dabei  aus Natrium und     112ethyl-p-tolylcarbinol    in  Gegenwart von     Camphersäureanhydrid    her  gestellt werden.

   Man erhält so das     methyl-          p-tolylcarbinolcamphersaure        Natrium,    ein  weisses hygroskopisches Pulver, das sich bei  Zimmertemperatur in Wasser zu 40 bis 50  löst.  



  Die neue Verbindung ist ebenso galletrei-         bend    wie das ihr zu Grunde liegende     Methyl-          p-tolylcarbinol.    Im Gegensatz zu diesem ist  sie aber bis zu 40 % in Wasser löslich. Ihre  Lösung     enthält    das wirksame     Methyl-p-tolyl-          carbinol    in leicht     abspaltbarer    und infolge  dessen hochwirksamer Form. Sie kann daher  zur Steigerung der     Gallesekretion    verwendet  werden.  



  Anderseits kann sie zur     Herstellung    an  derer     Salze    der     Methyl-p-tolylcarbinol-cam-          phersäure    mit anorganischen oder organi  schen Basen dienen. Zu diesem Zweck wird  aus dem     carbinolcamphersauren    Natrium,  z. B. durch Schwefelsäure, die     Carbinolcam-          phersäure        in.    Freiheit gesetzt und diese mit  anorganischen Basen, z. B. Ammoniak, an  dern     Alkalien,    Erdalkalien oder organischen  Basen, z.

   B.     Diäthanolamin    oder Äthylen  diamin     neutralisiert.            Beispiel:     Zu einer angewärmten     benzolischen    Lö  sung von 18,2 g     Camphersäureanhydrid    wird      eine     benzolische    Lösung von 13,6 g     Dlethyl-          p-tolylcarbinol,    in der 2,3 g Natrium gelöst  worden sind, zugefügt. Nach dem Erkalten  des Lösungsgemisches wird Wasser zugesetzt  und die     wässrige    Schicht, die das     metbyl-p-          tolylcarbinol-camphersaure    Natrium     enthält,     abgetrennt.



  Process for the preparation of methyl-p-tolylearbinol-amphersaurem sodium. It is known that the essential oil of the 'remoe Lawak drug and in particular the approximately 5% methyl-p-tolyl-carbinol contained in it has bile secretion-increasing effects. The therapeutic use of this alcohol stands in the way of its insolubility in water, which makes parenteral use in particular impossible.



  It has now been found that a new, easily water-soluble compound of 3Iethyl-p-tolylcarbinol can be produced by reacting sodium methyl-p-tolylearbinolate with camphoric anhydride in an organic solvent. The sodium - methyl - p - tolylcarbinolate can be made from sodium and 112ethyl-p-tolylcarbinol in the presence of camphoric anhydride.

   This gives sodium methyl-p-tolylcarbinolcamphoric acid, a white, hygroscopic powder which dissolves 40 to 50% in water at room temperature.



  The new compound is just as cholagogue as the methyl-p-tolylcarbinol on which it is based. In contrast to this, however, it is up to 40% soluble in water. Your solution contains the effective methyl-p-tolyl-carbinol in an easily cleavable and therefore highly effective form. It can therefore be used to increase bile secretion.



  On the other hand, it can be used to produce other salts of methyl-p-tolylcarbinol camper acid with inorganic or organic bases. For this purpose, sodium carbinolcamphoric acid, e.g. B. by sulfuric acid, the Carbinolcam- phersäure in. Freedom and this with inorganic bases, z. B. ammonia, on dern alkalis, alkaline earths or organic bases, z.

   B. diethanolamine or ethylene diamine neutralized. Example: A benzene solution of 13.6 g of methyl-p-tolylcarbinol, in which 2.3 g of sodium has been dissolved, is added to a heated benzene solution of 18.2 g of camphoric anhydride. After the mixed solution has cooled, water is added and the aqueous layer, which contains the methyl-p-tolylcarbinol-camphoric acid sodium, is separated off.
