Description

  

  Verfahren zur Herstellung einer wasserlöslichen Verbindung  der aromatischen Reihe.    Es wurde gefunden, dass man neue, was  serlösliche Abkömmlinge der aromatischen  Reihe erhält, wenn man     Verbindungen    von  folgendem schematischem Aufbau  
EMI0001.0002     
    wobei unter Ar aromatische Reste verstanden  werden,     g    in der     ms-Stellung    einen     aliphati-          schen    oder     alicyclischen        Substituenten    mit  mehr als 5     C-Atomen    bedeutet und die freien  Stellen der     aromatischen    Kerne beliebig, vor  nehmlich aber durch organische Reste substi  tuiert sein können,

   mit sulfonierenden Mitteln  behandelt.  



  Als Ausgangsmaterialien für die     Sulfonie-          rung    kommen die in der     ms-Stellung    durch       aliphatische    oder     alicyelische    Gruppen mit  mehr als 5     C-Aromen    substituierten     Desoxy-          benzoine    in Frage. Zu diesen zum Teil neuen  Verbindungen gelangt man leicht nach be  kannten Verfahren (siehe z. B.     Ber.    d. Deut-    sehen     Chem.    Gesellschaft     Bd.    21, Seite 1299  und     Bd.    25, Seite 2239.

   Die nach der     Sul-          fierung    dieser substituierten     Desoxybenzoine     erhaltenen Körper stellen in Form ihrer lös  lichen Metallsalze wertvolle Netz-,     Disper-          gier-    und     Emulgiermittel    dar, insbesondere  ist ihre     Weichmachungswirkung    interessant.  



  Gegenstand des vorliegenden Patentes ist  ein     Verfahren    zur Darstellung des Natron  salzes der     ms-Octodecyl-p-methyl-desoxyben-          zoinsulfonsäure,    das man durch     Sulfönierung     des     ms-Octodecyl-p-methyl-desoxybenzoins     und Neutralisierung der entstandenen     Sulfon-          säure    erhält.  



  Die neue Verbindung wird als helles Pul  ver erhalten, das in Wasser lehr leicht lös  lich ist und dessen Lösungen     Zelluloseregene-          raten    und     nativenZellulosenvorzüglicbeWeich-          heit    verleihen; wertvoll ist dabei die Eigen  schaft der neuen Verbindung,     Farbstofflösun-          gen        unbeein$usst    zu lassen, so dass ihre     Au-          weudung    im Färbebad erfolgen kann.

             Beispiel:     In 40 Teile Monohydrat werden, unter  Rühren bei<B>10'</B> C 20 Teile     ms-Octodecyl-p-          rnethyl    -     desogybenzoin    eingetragen, darauf  langsam bei 0-5   C 40 Teile     Oleum    (26      /oig)          zugetropft.    Nach vierstündigem Rühren unter  10 o C erweist sich eine in Wasser gegebene  Probe vollständig löslich. Sobald dies der Fall  ist, wird die Reaktionsmasse auf Eis gegos  sen, die ausgeschiedene freie     Sulfonsäure    ab  getrennt und durch Zusatz von Natronlauge  neutralisiert.

   Durch Eindampfen gewinnt man  das     Natronsalz    als helles Pulver, das in Was  ser sehr leicht löslich ist und dessen Lösun  gen     Zelluloseregeneraten    und nativen Zellu  losen vorzügliche Weichheit verleihen.



  Process for the preparation of a water-soluble aromatic series compound. It has been found that new, water-soluble derivatives of the aromatic series are obtained if compounds of the following schematic structure are used
EMI0001.0002
    where Ar is understood to mean aromatic radicals, g in the ms position denotes an aliphatic or alicyclic substituent with more than 5 carbon atoms and the free positions of the aromatic nuclei can be substituted as desired, but primarily by organic radicals,

   treated with sulfonating agents.



  The deoxybenzoins substituted in the ms position by aliphatic or alicyelic groups with more than 5 carbon aromas are suitable as starting materials for the sulfonation. These compounds, some of which are new, can easily be obtained using known processes (see, for example, Ber. D. Deut- see Chem. Gesellschaft Vol. 21, page 1299 and Vol. 25, page 2239.

   The bodies obtained after the sulfation of these substituted deoxybenzoins are valuable wetting agents, dispersing agents and emulsifying agents in the form of their soluble metal salts, and their softening effect is of particular interest.



  The subject of the present patent is a process for the preparation of the sodium salt of ms-octodecyl-p-methyl-deoxybenzoinsulfonic acid, which is obtained by sulfonating ms-octodecyl-p-methyl-deoxybenzoins and neutralizing the sulfonic acid formed.



  The new compound is obtained as a pale powder which is very easily soluble in water and whose solutions give cellulose regenerates and native cellulose excellent softness; What is valuable here is the property of the new compound of leaving dye solutions unaffected so that they can be thickened in the dye bath.

             Example: 20 parts of ms-octodecyl-p-methyl-desogybenzoin are introduced into 40 parts of monohydrate with stirring at 10 ° C., then 40 parts of oleum (26%) are slowly added dropwise at 0-5 ° C. . After four hours of stirring below 10 o C, a sample placed in water proves to be completely soluble. As soon as this is the case, the reaction mass is poured onto ice, the precipitated free sulfonic acid is separated off and neutralized by adding sodium hydroxide solution.

   The sodium salt is obtained as a pale powder by evaporation, which is very easily soluble in water and whose solutions give regenerated cellulose and native cellulose excellent softness.
