Description

  

  Verfahren zur Darstellung einer Verbindung der     Glutaminsäure    mit     Caleiumchlorid.       Es wurde gefunden, dass das saure     Calcium-          salz    der     Glutaminsäure,    mit     Calciumehlorid     eine     Verbindung    liefert, die bei 90-1000  getrocknet eine weisse, verwitterte Salzmasse  bildet, die gut kristallisiert vollständig luft  beständig und wasserlöslich ist. Sie enthält  auf 1     Mo1.        Glutaminsäure    1 Atom Chlor und  1 Atom     Calcium    neben 1     Mol.    Kristallwasser.

    Ihre Lösungen zeigen neutrale Reaktion und  angenehmen Geschmack. Man verfährt zu  ihrer Darstellung in der Weise; dass man die  Lösung des sauren     glutaminsauren        Calcium-          saize9        mit        Calciumchlorid    behandelt. Derselbe  chemische     Vorgang    findet auch dadurch statt,  dass ein Gemisch der     Glutaminsäure    . und  Salzsäure mit     Calciumkarbonat        abgesättigt     wird.

   Hierbei entsteht ebenfalls ab gesättigt  das saure     Calciumsalz    der     Glutaminsäure    und       Caleiumchlorid,    das dann dieselbe Verbindung  bildet.    <I>Beispiel 1:</I>  Ein Gemisch von 147 Gewichtsteilen       Glutaminsäure    und 1100     Gewichtsteilen        n-          Salzsäure    wird in der Wärme mit 110 Ge-         wichtsteilen        Calcirnnkarbonat        abgesiittigt    und  die erhaltene Lösung nach dem     Abfiltrieren     vom ungelösten     Calciumkarbonat    im Wasser  bad eingedampft.

   Die     neueV        erbiridung    scheidet  sich in     derben    glänzenden     Kristallkrusten    ab.  Nachdem bis zur starken Kristallisation ein  gedampft worden ist, wird erkalten gelassen,  abgesaugt, zunächst     finit        50",

  '.igeui        Alkohol     und     darauf    mit 90     "/oigein    Alkohol gewaschen  und schliesslich bei     90-100"        getrocknet.    Der  Rest der Verbindung wird     durch        vollständiges          Eindampfen    des Filtrats gewonnen und durch  Behandeln des Rückstandes mit Alkohol vom  etwa vorhandenen     überschüssigen        Calciuni-          chlorid    befreit..

      <I>Beispiel 2:</I>    In einer Lösung von     1e>6        C-xewielrtsteilen     saurem     glutaminsaureni        Kalk    in 2000 Ge  wichtsteilen Wasser werden     55,5    Gewichts  teile wasserfreies     Calciumchloi-id    gelöst und  diese Lösung im Wasserbade eingedampft.  Der Rückstand wird mit Alkohol verrieben,  abgesaugt,     finit    etwas     500/"igem    und darauf      mit 90     o/oigeni    Alkohol gewaschen und bei       90-100o        getrocknet.  



  Process for the preparation of a compound of glutamic acid with calcium chloride. It has been found that the acid calcium salt of glutamic acid, with calcium chloride, provides a compound which, when dried at 90-1000, forms a white, weathered salt mass that is well crystallized, completely air-resistant and water-soluble. It contains on 1 month. Glutamic acid 1 atom of chlorine and 1 atom of calcium in addition to 1 mol of crystal water.

    Your solutions show a neutral reaction and a pleasant taste. One proceeds in the same way for their presentation; that the solution of the acidic glutamic acid calcium salt9 is treated with calcium chloride. The same chemical process also takes place in that a mixture of glutamic acid. and hydrochloric acid is saturated with calcium carbonate.

   This also creates the acidic calcium salt of glutamic acid and calcium chloride when saturated, which then forms the same compound. Example 1: A mixture of 147 parts by weight of glutamic acid and 1100 parts by weight of n-hydrochloric acid is heated with 110 parts by weight of calcium carbonate and the solution obtained, after filtering off the undissolved calcium carbonate, evaporated in a water bath.

   The new fermentation is deposited in coarse, shiny crystal crusts. After it has been evaporated until strong crystallization, it is allowed to cool, suctioned off, initially finite 50 ",

  '.igeui alcohol and then washed with 90 "/ oigein alcohol and finally dried at 90-100". The remainder of the compound is obtained by complete evaporation of the filtrate and freed from any excess calcium chloride present by treating the residue with alcohol.

      <I> Example 2: </I> 55.5 parts by weight of anhydrous calcium chloride are dissolved in a solution of 1e> 6 C-xewielrtsteile acidic glutamic acid lime in 2000 parts by weight of water and this solution is evaporated in a water bath. The residue is triturated with alcohol, filtered off with suction, finely washed with something 500% strength and then with 90% alcohol and dried at 90-100 °.
