Description
Verfahren zur Herstellung eines neuen Esters. Es wurde gefunden, dass man einen neuen Ester erhält, wenn. man 4-Sulfophthalsä ure oder ein solches Derivat derselben, das durch Behandeln mit einem Alkohol in einen Car- bonsäureester der 4-Sulfophthalsäure über gehen kann, mit a-Chlor-ss-oxypropyl-do- decyläther zu einem Carbonsäuremonoester umsetzt.
Die Veresterung der Carboxylgruppe kann zum Beispiel, durch Emhitzender freien, Sulf on- eäure bezw. von,derenSalzen mit ,dem a-Chlor- ,B-oxypropyl-dodecylester erfolgen, gegebenen falls in Gegenwart von Lösungsmitteln, wie Pyridin, Cbinolin,
Dimethyl-p-toluidin und dergl. Besonders leicht reagiert das Carbon- säureanhydrid oder -chlorid. Carbonsäure- ester der 4-Sulfophthalsäure lassen sich mit dem a-Chlor-,B-oxypropyl-dodecyläther Um- estern. Bei der Veresterung können konzen trierte Schwefelsäure, Chlorwasserstoffgas oder andere,
die Veresterung beschleunigende Mittel hinzugefügt werden. Die Veresterung wird erleichtert, wenn man das bei der Re- aktion sich bildende Wasser aus dem Ver- esterungsgemisch in bekannter Weise ent fernt, beispielsweise mit Hilfe solcher Stoffe, die mit Wasser azeotrope Mischungen bilden. Das abgespaltene Wasser kann auch durch Arbeiten unter vermindertem Druck entfernt werden.
Der neue Ester stellt nach dem Neutrali sieren und Trocknen eine feste, pulverisier- bare Masse dar, die von Wasser leicht zu einer beim Schütteln stark schäumenden Lö sung aufgenommen wird.
Der gemäss vorliegendem Verfahren her zustellende Ester kann dank seiner kapillar aktiven Eigenschaften beispielsweise als Netz-, Reinigungs-, Wasch-, Dispergier-, Egalisier- und Weichmachungsmittel, insbe sondere als Schaummittel, z.
B. für Feuer- löschzwecke, oder als Waschmittel für leben des Haar Verwendung finden. Der neue Ester kann allein oder zusammen mit andern geeigneten Stoffen, wie Lösungsmitteln, Sal zen ein- oder mehrwertiger Metalle, Seifen oder seifenartigen Stoffen oder Sehutzkol- loiden Anwendung finden.
Beispiel: Laurinalkohol wird nach dem Verfahren der österreichischen Patentschrift \r. 749988 in den a-Chlor-ss-oxypropyläther umgewan delt (durch Behandeln mit Epichlorhydrin in (legenwart von Schwefelsäure bei 1U(1 ).

Das in Wasser gelöste Ver- esterungsprodukt wird darauf mit konzen trierter Iialiumliydroxydlösung neutralisiert und zur Trockne verdampft. zweckmässig unter vermindertem Druck. Man erhält eine annähernd farblose, feste Masse, deren wäs serige Lösungen beim Sehütteln schäumen. Gegebenenfalls vorhandene geringe Mengen an Verunreinigungen können durch Extrak tion des trockenen Salzes mit einem organi schen Lösungsmittel. z.

Process for the preparation of a new ester. It has been found that a new ester is obtained when. 4-sulfophthalic acid or such a derivative thereof, which can be converted into a carboxylic acid ester of 4-sulfophthalic acid by treatment with an alcohol, is reacted with α-chloro-β-oxypropyl-dodecyl ether to form a carboxylic acid monoester.
The esterification of the carboxyl group can, for example, bezw by heating the free sulfonic acid. of, the salts of which with, the a-chloro, B-oxypropyl-dodecyl ester, if necessary in the presence of solvents such as pyridine, Cbinolin,
Dimethyl-p-toluidine and the like. The carboxylic acid anhydride or chloride reacts particularly easily. Carboxylic acid esters of 4-sulfophthalic acid can be transesterified with the α-chloro, B-oxypropyl dodecyl ether. During the esterification, concentrated sulfuric acid, hydrogen chloride gas or other
the esterification accelerating agents are added. The esterification is facilitated if the water formed during the reaction is removed from the esterification mixture in a known manner, for example with the aid of substances which form azeotropic mixtures with water. The water split off can also be removed by working under reduced pressure.
After neutralization and drying, the new ester is a solid, pulverizable mass that is easily absorbed by water to form a strongly foaming solution when shaken.
The esters to be produced according to the present process can be used, for example, as wetting, cleaning, washing, dispersing, leveling and softening agents, especially as foaming agents, e.g.
B. for fire extinguishing purposes, or as a detergent for the life of the hair use. The new ester can be used alone or together with other suitable substances, such as solvents, salts of monovalent or polyvalent metals, soaps or soap-like substances or protective colloids.
Example: Lauric alcohol is produced according to the Austrian patent \ r. 749988 converted into a-chloro-ss-oxypropyl ether (by treatment with epichlorohydrin in (presently of sulfuric acid at 1U (1).
: 5 parts by weight of the -Aether obtained in this way (bp.,: I .; 19: 3 to? 03 C) are gradually converted into 5 with stirring at <B> 70 </B> to <B> 90 </B> " Parts by weight of 4-sulfophthalic anhydride (containing 41 pure 4-sulfophthalic anhydride (1) are incorporated. The mixture is stirred for a short time and allowed to cool.
The esterification product, dissolved in water, is then neutralized with a concentrated iialium hydroxide solution and evaporated to dryness. expediently under reduced pressure. An almost colorless, solid mass is obtained, the aqueous solutions of which foam when shaken. Any small amounts of impurities that may be present can be removed by extracting the dry salt with an organic solvent. z.
