Description
Verfahren zur Herstellung eines neuen, als Hilfsmittel für die Textilindustrie wertvollen Estergemisehes. <B>Es</B> wurde gefunden, dass man ein neues, als Hilfsmittel für die Textilindustrie wert volles, aus dem Mono- und Diamylcarbon- säureester bestehendes Estergemisch erhält, wenn man die Sulfo-4-chlorphthalsäure, wel che erhalten wird durch Sulfieren von 4-Chlor- phthalsäure mit SOa, oder ein solches Derivat derselben,
das durch Behandlung mit einem Alkohol in einen Ester der Sulfo-4-chlorphthal- säure übergehen kann, wie das Anhydrid oder die Halogenide dieser Säure, mit Gährungs- amylalkohol behandelt.
Zur Veresterung kann man beispielsweise die Sulfo-4-chlorphthalsäure beziehungsweise deren Anhydrid oder Chlorid oder Salze mit Gährungsamylalkohol erhitzen, gegebenenfalls unter Zusatz von Chlorwasserstoffgas, kon zentrierter Schwefelsäure oder anderer, die Veresterung beschleunigender Mittel.
Die Ver- esterung wird erleichtert, wenn man das bei der Reaktion sich bildende Wasser aus dem Veresterungsgemisch in bekannter Weise ent- fernt, beispielsweise mit Hilfe solcher Stoffe die mit Wasser azeotrope Mischungen bilden. Statt von den Säurechloriden auszugehen, kann man dieselben auch erst während der Veresterung entstehen lassen, zum Beispiel unter Anwendung von Phosphoroxychlorid und dergleichen.
Die zu veresternde Sulfo- 4-chlorphthalsäure braucht nicht in reinem Zustande vorzuliegen, man kann dieselbe auch in der Form verwenden, die man erhält, wenn man 4-Chlorphthalsäureanhydrid durch Erhit zen mit Schwefelsäureanhydrid unter Druck sulfiert und die Sulfiermasse vom grössten Teil des überschüssig angewendeten Sulfonierungs- mittels befreit.
Der zu veresternde Giihrzingsamylalkohol braucht weder in hochprozentigem, noch in wasserfreiem Zustande zur Anwendung zu gelangen, man kann z. B. von Fuselöl oder Sulfitspritfuselöl ausgehen. Man kann auch einen solchen Amylalkohol verwenden, der mindestens einen Hauptbestandteil des Gäh- rungsamylalkohols in überwiegender Menge enthält, z. B. Isoamylalkohol.
Das neue Estergemisch stellt nach dem Neutralisieren und Trocknen ein gelblich ge färbtes Pulver dar, das in Wasser leicht lös lich ist und ein ausgesprochenes Netz-, Rei- nigungs- und Emulgierungsvermögen besitzt. Das Estergemisch kann daher für die mannig faltigsten industriellen Zwecke Verwendung finden.
<I>Beispiel:</I> 18,9 Gewichtsteile 4-Chlorphtlialsäurean- hydrid werden in einem geschlossenen Gefäss durch Erhitzen mit 33,2 Gewichtsteilen Schwefelsäureanhydrid während 10 Stunden auf 205-210 in die Sulfosäure übergeführt. Man entfernt darauf den grössten Teil des im Überschuss angewandten Sulfonierungs- mittels durch längeres Erhitzen auf 190-200 .
24,2 Gewichtsteile Sulfonierungsmasse, ent haltend 21,3 Gewichtsteile Sulfo-chlorphthal- säureanhydrid werden darauf mit 28,7 Ge wichtsteilen Amylalkohol auf dem siedenden Wasserbade bis zur praktisch vollständigen Lösung erhitzt. Nachdem man die Tempera tur rasch auf 1200 gesteigert hat, lässt man erkalten. Das Reaktionsprodukt ist eine homo gene Flüssigkeit, die von Wasser zu einer klaren, beim Schütteln stark schäumenden Lösung aufgenommen wird.
Man kann- auch nach dem Neutralisieren zur Trockne ver dampfen, wobei man ein leicht pulverisier- bares, gelblich gefärbtes Produkt erhält, wel. ches in Wasser oder garbonisiersäure ausge zeichnet netzt.
Process for the production of a new ester mixture which is valuable as an auxiliary for the textile industry. It has been found that a new ester mixture, which is valuable as an auxiliary for the textile industry and consists of the mono- and diamylcarboxylic acid ester, is obtained if the sulfo-4-chlorophthalic acid is obtained by Sulphonation of 4-chlorophthalic acid with SOa, or such a derivative thereof,
which can be converted into an ester of sulfo-4-chlorophthalic acid by treatment with an alcohol, such as the anhydride or the halides of this acid treated with fermentation amyl alcohol.
For esterification, for example, the sulfo-4-chlorophthalic acid or its anhydride or chloride or salts with fermentation amyl alcohol can be heated, optionally with the addition of hydrogen chloride gas, concentrated sulfuric acid or other agents which accelerate the esterification.
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. Instead of starting from the acid chlorides, they can also only be formed during the esterification, for example using phosphorus oxychloride and the like.
The sulfo-4-chlorophthalic acid to be esterified does not have to be in the pure state; it can also be used in the form that is obtained when 4-chlorophthalic anhydride is sulfated by heating with sulfuric anhydride under pressure and the sulfonating mass from most of the excess used Sulfonating agent freed.
The Giihrzingsamylalkohol to be esterified does not need to be used either in a high percentage or in an anhydrous state; B. assume fusel oil or sulphite fuel oil. One can also use such an amyl alcohol which contains at least one main component of the fermentation amyl alcohol in a predominant amount, e.g. B. Isoamyl alcohol.
After neutralization and drying, the new ester mixture is a yellowish colored powder, which is easily soluble in water and has excellent wetting, cleaning and emulsifying properties. The ester mixture can therefore be used for a wide variety of industrial purposes.
<I> Example: </I> 18.9 parts by weight of 4-chlorophthalic anhydride are converted into the sulfonic acid by heating with 33.2 parts by weight of sulfuric anhydride for 10 hours to 205-210 in a closed vessel. The major part of the sulfonating agent used in excess is then removed by prolonged heating to 190-200.
24.2 parts by weight of sulfonation compound, containing 21.3 parts by weight of sulfo-chlorophthalic anhydride, are then heated with 28.7 parts by weight of amyl alcohol on the boiling water bath until practically complete solution. After the temperature has been quickly increased to 1200, it is allowed to cool. The reaction product is a homogeneous liquid that is absorbed by water to form a clear solution that foams strongly when shaken.
You can also evaporate to dryness after neutralization, giving an easily pulverizable, yellowish colored product, wel. ches in water or garbonizing acid excellently wets.
