Die Darstellung von Estern aromatischerThe appearance of esters more aromatic
Carbonsäuren durch Umsetzung der Salze aromatischer Carbonsäuren mit Halogeniden von Alkoholen ist in vielen Fällen mit Schwierigkeiten verknüpft.Carboxylic acids by reacting the salts of aromatic carboxylic acids with halides alcohol is associated with difficulties in many cases.
Es hat sich nun gezeigt, daß die Umsetzung carbonsaurer Salze mit Alkoholhalogeniden meist glatter verläuft, wenn man sie in Gegenwart organischer Basen ausführt. Als geeigneteIt has now been shown that the reaction of carboxylic acid salts with alcohol halides usually runs smoother when done in the presence of organic bases. As suitable
ίο Basen seien beispielsweise genannt Trialkylamine, Pyridin, Chinoline Piperidin, ferner Dimethylanilin, Anilin selbst usw. Es genügen schon sehr kleine Zusätze dieser Basen für die beschriebene Wirkung. Statt der Salze der Carbonsäuren können auch die freien Carbonsäuren oder innere Salze solcher (wie sie z. B. in manchen Phtaleinfarbstoffbasen vorliegen) unter Zusatz von basischen Mitteln benutzt werden.ίο Bases are, for example, trialkylamines, Pyridine, quinolines, piperidine, also dimethylaniline, Aniline itself, etc. Even very small additions of these bases are sufficient for the described effect. Instead of the salts The carboxylic acids can also be the free carboxylic acids or internal salts of such (such as she z. B. in some phthalein dye bases) with the addition of basic agents to be used.
Die so erhaltenen Ester können zur Darstellung von Farbstoffen und pharmazeutischen Präparaten verwendet werden.The esters thus obtained can be used for the preparation of dyes and pharmaceuticals Preparations are used.
N Beispiel I. N Example I.
100 Teile fein gepulvertes Kaliumbenzoat werden mit 120 Teilen Benzylchlorid und ι Teil Triäthylamin 30 Minuten auf 95 bis 100° erwärmt. Aus der durch fein verteiltes Chlorkalium getrübten Flüssigkeit kann das das Benzylbenzoat durch Aufnehmen in Äther, • Filtrieren und fraktionierte Destillation leicht gewonnen werden. Es siedet bei 316 bis 317 ° (vgl. Kohn und Trantom [Soc. 75, 1155]).100 parts of finely powdered potassium benzoate are mixed with 120 parts of benzyl chloride and ι part of triethylamine heated to 95 to 100 ° for 30 minutes. From the finely divided Potassium chlorinated liquid can destroy the benzyl benzoate by being absorbed in ether, • Filtration and fractional distillation are easily obtained. It boils at 316 to 317 ° (see Kohn and Trantom [Soc. 75, 1155]).
Beispiel II. 3gExample II. 3 g
Ein Gemisch von 160 Teilen Isoamylbromid, 100 Teilen benzoesaurem Kali und 1 Teil Pyridin wird 30 bis 40 Minuten auf 120 bis 125 ° erhitzt. Die Aufarbeitung des Reaktionsgemisches geschieht, wie in Beispiel I angegeben. Das so gewonnene Isoamylbenzoat besitzt die in der Literatur beschriebenen Eigenschaften.A mixture of 160 parts of isoamyl bromide, 100 parts of potassium benzoate and 1 part of pyridine is heated to 120 to 125 ° for 30 to 40 minutes. Working up the reaction mixture happens as indicated in Example I. The isoamyl benzoate obtained in this way has those described in the literature Properties.
Beispiel III.Example III.
Ein Gemenge von 10 Teilen Diäthylrhodamin (Base), 6 Teilen Kaliumcarbonat, 30 Teilen Benzylchlorid und 0,2 Teilen Triäthylamin wird unter Rühren eine Stunde lang auf 115 bis 120° erhitzt. Man destilliert dann das überschüssige Benzylchlorid mit Wasserdampf ab und kocht den Rückstand mit schwacher Salzsäure wiederholt aus. Durch Fällen der salzsauren Lösung mit Kochsalz erhält man das Chlorhydrat des Diäthylrhodaminbenzylesters als metallisch glänzende Masse. Es löst sich leicht in Wasser und Alkohol mit blauroter Farbe und lebhafter grüngelber Fluoreszenz; die Lösung in konzentrierter Schwefelsäure ist zitronengelb. Aus der wässerigen Lösung fällen Alkalien den freien Benzylester in ziegelroten Flocken.A mixture of 10 parts of diethyl rhodamine (base), 6 parts of potassium carbonate, 30 parts Benzyl chloride and 0.2 part of triethylamine are stirred for one hour at 115 heated to 120 °. The excess benzyl chloride is then distilled with steam and the residue is repeatedly boiled with weak hydrochloric acid. By felling the Hydrochloric acid solution with common salt gives the hydrochloride of diethyl rhodamine benzyl ester as a shiny metallic mass. It dissolves easily in water and alcohol with a blue-red color and a more vivid green-yellow color Fluorescence; the solution in concentrated sulfuric acid is lemon yellow. From the watery Solution, alkalis precipitate the free benzyl ester in brick-red flakes.

The reaction mass is diluted with alcohol and the solution is filtered off hot from the precipitated potassium chloride. On cooling, pure ethyl 2-anthraquinonylcarbonylglycolate crystallizes. It is insoluble in water, dilute acids and alkalis, rather easily soluble in hot alcohol, glacial acetic acid and benzene, in Figure 10, where it during cooling in fine, weak: crystallized 'yellow needles of melting point 13g to / 140 0th Its solution in concentrated sulfuric acid is lemon yellow.

■'/ ■ Beispiel V.■ '/ ■ Example V.
Man erwärmt 100 Teile i-chloranthrachinon-2-carbonsaures Kali mit 120 Teilen Benzylchlorid und 2 Teilen Pyridin auf 95 bis 100 ° und rührt die Mischung 30 Minuten bei dieser Temperatur. Nach dem Abdestillieren des unverbrauchten Benzylchlorids im Vakuum oder mit Dampf hinterbleibt der i-Chloranthrachinon-2-carbonsäurebenzylester als gelblich gefärbtes Kristallpulver in nahezu chemisch reinem Zustand. Ganz rein erhält man ihn durch Umkristallisieren aus Eisessig oder Alkohol unter Zusatz von Tierkohle. Er bildet schwach gelblich gefärbte Nadeln vom Schmelzpunkt 135 bis 136 °. Er ist unlöslich in Wasser, verdünnten Säuren und Alkalien, schwer löslich in kaltem Alkohol, Äther, Eisessig, leicht in kochendem Eisessig und höher siedenden Lösungsmitteln.' In konzentrierter Schwefelsäure löst er sich mit gelber Farbe unter Verseifung.100 parts of i-chloroanthraquinone-2-carboxylic acid are heated Potash with 120 parts of benzyl chloride and 2 parts of pyridine to 95 to 100 ° and stir the mixture for 30 minutes at this temperature. After distilling off the benzyl i-chloranthraquinone-2-carboxylate remains behind unused benzyl chloride in vacuo or with steam as a yellowish colored crystal powder in an almost chemically pure state. You can get it completely pure by recrystallization from glacial acetic acid or alcohol with the addition of animal charcoal. He educates pale yellowish colored needles with a melting point of 135 to 136 °. He is insoluble in Water, diluted acids and alkalis, sparingly soluble in cold alcohol, ether, glacial acetic acid, easily in boiling glacial acetic acid and higher boiling solvents. ' In concentrated Sulfuric acid, it dissolves with a yellow color with saponification.
Man kann die Reaktion auch in Gegenwart von Verdünnungsmitteln, wie Nitrobenzol, Chlorbenzol usw., ausführen; das Pyridin kann durch Chinolin, Triäthylamin, Piperidin, Dimethylanilin usw. ersetzt werden.The reaction can also be carried out in the presence of diluents such as nitrobenzene or chlorobenzene etc., execute; the pyridine can be replaced by quinoline, triethylamine, piperidine, dimethylaniline etc. to be replaced.
Führt man dagegen die Reaktion in Ab-Wesenheit einer organischen Base aus, so ist mehrstündiges Kochen des Gemisches nötig, um eine quantitative Umsetzung zu erzielen.If, on the other hand, the reaction is carried out in the absence of an organic base, then is several hours of cooking the mixture necessary to achieve quantitative conversion.
