Description

  

  Verfahren zur Herstellung des     Triaerylsäureesters    des hydrierten Rizinusöles.    Es wurde     gefunden,    dass man den     Tri-          aery        lsäureestei-    des gehärteten Rizinusöles  herstellen kann, wenn man gehärtetes Ri  zinusöl unter Zusatz     einer        Säure    in Gegen  wart von     Niekelearbonvl    mit Azetylen be  handelt.  



  Die     Herstellung    kann in der Weise vorge  nommen werden, dass man die Reaktionskom  ponenten bei     Raumtemperatur    oder bei erhöh  ter Temperatur miteinander     iniseht.    Die Um  setzung kann unter     Atmosphärendruck    oder  gegebenenfalls in einem Druckgefäss unter  schwachem     Überdruck    bei     Rauinteniperatur     oder bei mässig erhöhter Temperatur, z. B. bei  30 bis 80" C,     vorgenommen    werden.

   Man kann  beispielsweise Azetylen in eine     llisehung    aus  dem gehärteten Rizinusöl und der Säure ein  leiten und gleichzeitig das     Nielreleai-bonyl        ztt-          tropfen.        Noeli        zweekinä        ssiger    ist es, das gehär  tete Rizinusöl, die Säure und das     Nickelcarbo-          nyl    - gegebenenfalls unter Zusatz eines Lö  sungsmittels -     zii        inisehen    und in einer ge  eigneten Schüttelapparatur mit Azetylen un  ter geringem Überdruck zu schütteln.  



  Falls unter     At.niosphärendruek    gearbeitet  werden soll, sind auf 1     Mol    Azetylen minde  stens     1#        Mol        Niekelearbonyl,    mindestens     1:;;        Mol     einer einbasischen Säure und mindestens       '/3        Mol    des gehärteten     Rizinusöles        anzuwendem     Beim Arbeiten im Druckgefäss und bei erhöh  ter Temperatur, z.

   B. bei 120 bis 150  C, kann  die Menge des     Niekelearbonyls    reduziert  werden, wobei aber     Kohlenmonoxyd    im     über-          sehuss        zugegen    sein muss.<B>Es</B> ist sogar möglich,    das     Niekelearbonyl    bei der     Umsetzung-    bei er  höhter Temperatur und unter Druck erst  während der Reaktion entstehen zu lassen, in  dem man in Gegenwart von metallischem  Nickel oder dessen Salzen, insbesondere Halo  geniden, und unter Zusatz von überschüssigem  Kohlenmonoxyd arbeitet.

   In diesem Falle sind  nur geringe Mengen an     Nickel.    oder dessen  Salzen     erforderlieb,    da diese Zusätze als Ka  talysator wirken.  



  Als Säuren können beim vorliegenden Ver  fahren beispielsweise Halogenwasserstoff  säuren, insbesondere Salzsäure, ferner Phos  phorsäure oder Essigsäure benützt werden.  Sie werden vorteilhaft in wässriger Lösung  angewendet.  



  Der neue Ester bildet ein     (il,    welches in  den meisten Lösungsmitteln leicht löslich ist.       Er    kann als     Zwischenprodukt.,    beispielsweise  zur Herstellung von     Polynierisaten,    die z. B.  als     Textilhilfsstoffe,Klebemittel    sowie als Be  standteile von Kunstmassen und Lacken Ver  wendung finden können,     Anwendung    finden.  <I>Beispiel:</I>  74 Teile gehärtetes     Rizinusöl    werden in  einer Mischung von 135 Teilen Benzol und  115 Teilen Benzin in der Wärme gelöst.

   Die  warme Lösung wird nach     Versetzen    mit 18  Teilen konzentrierter Salzsäure (d=1,199)  und 10 Teilen     Nickelearbonyl    mit Azetylen       gesehüt.telt,    bis kein Gas mehr absorbiert wird.       Anfä        nglieli    erfolgt. ein     Farbumschlag    nach       Dunkelbraun,    und     iin    Verlauf der Reaktion      hellt die Farbe wieder auf und es scheidet  sich festes     NiClx    ab, während eine beträcht  liche Selbsterwärmung auftritt.  



  Nach dem Erkalten filtriert man vom aus  geschiedenen Nickelchlorid ab und destilliert  das     Lösungsmittel    unter vermindertem  Druck ab.  



  Man erhält 80 Teile des     Triacrylsäureesters     des hydrierten Rizinusöles, der in den meisten  Lösungsmitteln leicht löslich ist. Durch Er  hitzen auf dem Wasserbad in Gegenwart von  etwas     Benzoylperoxyd    (z. B. 0,1     %    ) wird der  neue Ester innerhalb kurzer Zeit (3 bis 10  Minuten) polymerisiert, wobei eine hornartige,       zerreibbare    Masse entsteht.



  Process for the preparation of the triaerylic acid ester of hydrogenated castor oil. It has been found that the triarylic acid ester can be produced from hardened castor oil if hardened ricinus oil is treated with acetylene with the addition of an acid in the presence of Niekelearbonvl.



  The preparation can be undertaken in such a way that the reaction components are iniseht with one another at room temperature or at an elevated temperature. The conversion can take place under atmospheric pressure or, if appropriate, in a pressure vessel under a slight excess pressure at Rauinteniperatur or at a moderately elevated temperature, e.g. B. at 30 to 80 "C, can be made.

   For example, acetylene can be introduced into a solution of the hardened castor oil and the acid and the nielreleai-bonyl can be added at the same time. It is more difficult for Noeli to see the hardened castor oil, the acid and the nickel carbonyl - if necessary with the addition of a solvent - and to shake them in a suitable shaker with acetylene under a slight overpressure.



  If work is to be carried out under atmospheric pressure, at least 1 mol of Niekelearbonyl, at least 1: ;; Mol of a monobasic acid and at least 1/3 mol of the hardened castor oil to be used. When working in a pressure vessel and at elevated temperature, eg.

   B. at 120 to 150 C, the amount of Niekelearbonyl can be reduced, but carbon monoxide must be present in excess. <B> It </B> is even possible to use the Niekelearbonyl during the reaction - at elevated temperature and to be created under pressure only during the reaction, in which one geniden in the presence of metallic nickel or its salts, especially halo, and with the addition of excess carbon monoxide works.

   In this case there are only small amounts of nickel. or its salts required, since these additives act as a catalyst.



  The acids used in the present process are, for example, hydrohalic acids, in particular hydrochloric acid, and also phosphoric acid or acetic acid. They are advantageously used in aqueous solution.



  The new ester forms a (il, which is easily soluble in most solvents. It can be used as an intermediate product, for example for the production of polynes, which can be used, for example, as textile auxiliaries, adhesives and as components of plastics and lacquers , Application. <I> Example: </I> 74 parts of hydrogenated castor oil are dissolved in a mixture of 135 parts of benzene and 115 parts of gasoline in the heat.

   After adding 18 parts of concentrated hydrochloric acid (d = 1.199) and 10 parts of nickel carbonyl, the warm solution is protected with acetylene until no more gas is absorbed. Initially done. a color change to dark brown, and in the course of the reaction the color lightens again and solid NiClx separates out, while considerable self-heating occurs.



  After cooling, the precipitated nickel chloride is filtered off and the solvent is distilled off under reduced pressure.



  80 parts of the triacrylic acid ester of hydrogenated castor oil, which is readily soluble in most solvents, are obtained. By heating it on a water bath in the presence of some benzoyl peroxide (e.g. 0.1%), the new ester is polymerized within a short time (3 to 10 minutes), producing a horn-like, friable mass.
