Description
Yerfaluren zur Herstellung eines neuen, als Hilfsmittel für die Textilindustrie wertvollen Estergemisclies. Es wurde gefunden, dass mau ein neues, als Hilfsmittel für die Textilindustrie wert volles, aus dem Mono- und Dicarbonsäureester des Hexadecyl- und des Octadecylalkohols bestehendes, Estergemisch erhält, wenn man Plithalsäure-R-sulfosäure oder ein solches Derivat derselben,
das durch Behandlung mit einem Alkohol in einen Ester der Phthal- säure-@3-sulfosäure übergeben kann, wie das Anhydrid oder die Halogenide dieser Säure, finit einem handelsüblichen Gemisch aus nor malem Hexadecyl- und Octadecylalkohol be handelt.
Zur Veresterung kann man beispielsweise Phthalsäure-p-sulfosäure bezw. deren An hydrid oder Chlorid oder Salze mit einem handelsüblichen Gemisch aus normalem Hexa- decyl- und Octadecylalkohol erhitzen, gege benenfalls unter Zusatz von Chlorwasserstoff gas, konzentrierter Schwefelsäure oder anderer, die Veresterung beschleunigender Mittel.
Die Veresterung wird erleichtert, wenn man das bei der Reaktion sich bildende Wasser aus dem Veresterungsgemisch in bekannter Weise entfernt, beispielsweise mit Hilfe solcher Stoffe, die mit Wasser azeotrope Mischungen bilden. Statt von den Säurechloriden auszu gehen, kann man dieselben auch erst während der Veresterung entstehen lassen, zum Bei spiel unter Anwendung von Phosphoroxy- chlorid und dergleichen.
Die zu veresternde Phthalsäure-ss-sulfosäure braucht nicht in reinem Zustande vorzuliegen, man kann die selbe auch in der Form verwenden, die man erhält, wenn man Phthalsäureanhydrid durch Erhitzen mit Schwefelsäureanhydrid unter Druck sulfiert und die Sulfiermasse vom gröss tem Teil des überschüssig angewendeten Sulfonierungsmittels befreit. In diesem Falle ist es zweckmässig, das noch vorhandene Sul- fonierungsmittel durch einen Zusatz von Soda abzustumpfen.
Das neue Estergemisch stellt nach dem Neutralisieren und Trocknen ein schwach grau gefärbtes Pulver dar, das in Wasser beim Erwärmen löslich ist und ein ausgesprochenes Netz- und Emulgierungsvermögen besitzt. Das Produkt eignet sich ausgezeichnet als Waschmittel, insbesondere in hartem Wasser und verhindert die Abscheidung von Kalk seifen. Das Estergemisch kann daher für die mannigfaltigsten industriellen Zwecke Ver wendung finden.
<I>Beispiel:</I> In einem Autoklaven wird Phthalsäure- anbydrid durch mehrstündiges Erhitzen mit 3 Mol Schwefelsäureanhydrid auf 145-1b0 in das Sulfophthalsäureanhydrid übergeführt. Mit Hilfe eines trockenen Luftstromes oder durch längeres Erhitzen auf 190-200' bringt nian darauf den Gehalt der Sulfierinasse an überschüssigem Sulfonierungsmittel auf etwa 11 /o.
In 47,8 Gewicbtateile der so erhaltenen Sulfiermasse, welche auf etwa 145' erhitzt ist, trägt man 3,6 Gewichtsteile caleinierte Soda ein. Wenn sich die Soda praktisch völlig gelöst hat, fügt man unter Rühren zu der auf etwa<B>800</B> erkalteten Masse 53 Ge wichtsteile der geschmolzenen handelsüblichen Mischung aus Hexadecyl- und Octadecylal- kohol in kleinen Anteilen hinzu, derart, dass die Temperatur unter etwa 90 bleibt. Man rührt zuletzt einige Zeit bei 80-90 nach und lässt erkalten. Das mit warmem Wasser zu einer homogenen Paste verriebene Produkt wird darauf neutralisiert und zur Trockne verdampft, zweckmässig unter vermindertem Druck.
Man erhält ein schwach grau gefärb tes Pulver, das in Wasser beim Erwärmen löslich ist und ein ausgesprochenes Netz- und Emulgierungsvermögen besitzt. Das Produkt eignet sich ausgezeichnet als Waschmittel, zum Beispiel für Schweisswolle, und verhindert die Abscheidung von Kalkseifen.
Yerfaluren for the production of a new ester mixture that is valuable as an aid for the textile industry. It has been found that a new ester mixture consisting of the mono- and dicarboxylic acid esters of hexadecyl and octadecyl alcohol, which is valuable as an aid for the textile industry, is obtained if plithalic acid-R-sulfonic acid or such a derivative thereof is obtained,
which can be passed into an ester of phthalic acid @ 3-sulfonic acid by treatment with an alcohol, such as the anhydride or the halides of this acid, finite a commercial mixture of normal hexadecyl and octadecyl alcohol.
For esterification, for example, phthalic acid-p-sulfonic acid can be used. Heat their anhydride or chloride or salts with a commercially available mixture of normal hexadecyl and octadecyl alcohol, if necessary with the addition of hydrogen chloride gas, concentrated sulfuric acid or other agents that accelerate the esterification.
The esterification is facilitated if the water formed in 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 phthalic acid-ß-sulfonic acid to be esterified does not need to be in a pure state; it can also be used in the form that is obtained when phthalic anhydride is sulfated by heating with sulfuric anhydride under pressure and the sulfonating mass contains the largest part of the excess sulfonating agent used freed. In this case it is advisable to blunt the sulphonating agent still present by adding soda.
After neutralization and drying, the new ester mixture is a pale gray colored powder that is soluble in water when heated and has a pronounced wetting and emulsifying power. The product is ideal as a detergent, especially in hard water, and prevents soaps from separating out. The ester mixture can therefore be used for a wide variety of industrial purposes.
<I> Example: </I> In an autoclave, phthalic anhydride is converted into sulfophthalic anhydride by heating it with 3 mol of sulfuric anhydride to 145-1b0 for several hours. With the aid of a stream of dry air or by prolonged heating to 190-200 minutes, the excess sulfonating agent content of the sulfonating agent is then brought to about 11 / o.
In 47.8 parts by weight of the sulphonation mass thus obtained, which is heated to about 145 ', 3.6 parts by weight of caleined soda are introduced. When the soda has practically completely dissolved, 53 parts by weight of the melted commercial mixture of hexadecyl and octadecyl alcohol are added in small proportions to the mass, which has cooled to about 800, while stirring, so that the Temperature stays below about 90. Finally, stir for a while at 80-90 and let cool. The product, triturated with warm water to form a homogeneous paste, is then neutralized and evaporated to dryness, conveniently under reduced pressure.
A pale gray colored powder is obtained which is soluble in water when heated and has pronounced wetting and emulsifying properties. The product is ideal as a detergent, for example for welding wool, and prevents lime soaps from separating out.
