Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 154507. Verfahren zur Herstellung eines als Netz-, Reinigungs-, Emulgiermittel ete. geeigneten Produktes. In der Hauptanmeldung ist ein Verfahren zur Herstellung eines als Netz-, Reinigungs-, Emulgiermittel etc. geeigneten Produktes be schrieben, bei dem man Sulfoessigsäure in der Carboxylgruppe mit Oleinalkohol verestert.
Es wurde nun gefunden, dass man in ganz analoger Weise ein wertvolles Produkt erhält, wenn man Sulfoessigsäure in der Carboxyl- gruppe mit Octodecylalkohol verestert. Der Octodecylalkohol kann beispielsweise erhalten werden durch Reduktion von<B>Öl-</B> oder Stearin säure beziehungsweise deren Estern. Man kann ferner den Octodecylalkohol auch ge winnen durch Reduktion von tierischen oder pflanzlichen Ölen beziehungsweise Fetten, wie Sojaöl, Erdnussöl etc.
Die Veresterung kann in üblicher Weise erfolgen. Zweckmässig erhitzt man die Sulfo- essigsäure mit Octodecylalkohol auf etwa 100 C, wobei es vorteilhaft ist, durch An wendung von Vakuum das bei der Vereste- rung freiwerdende Wasser zu entfernen.
Statt der freien Sulfoessigsäure kann man auch das Monoalkalisalz, zum Beispiel das Mono natriumsalz, verwenden, das man leicht durch Neutralisieren der wässerigen Lösung der Sulfoessigsäure mit Natronlauge bis zum Verschwinden der kongosauren Reaktion er hält, wobei ein Äquivalent an Alkali, bezogen auf die Sulfogruppe, verbraucht wird. Erhitzt man das auf diese Weise erhaltene Natrium salz mit der äquivalenten Menge Octodecyl- alkohol auf etwa 180 C, so tritt Veresterung ein.
An Stelle der Sulfoessigsäure kann man auch Derivate der Sulfoessigsäure, beispiels weise die Ester oder Halogenide, verwenden.
Die auf die beschriebene Weise herge stellte Verbindung stellt ein farbloses Produkt dar und eignet sich ebenso wie das nach dem Verfahren der Hauptanmeldung erhält liche Produkt vor allem als Wasch-, Emulgier-, Netzmittel etc. und kann insbesondere in der Textilindustrie in vielseitiger Weise Verwen dung finden.
<I>Beispiel:</I> 162 Teile 1>Iononatriumsalz der -Sulfoessig- säure werden mit 270 Teilen Octodecylalko- hol 8 Stunden lang unter Rühren auf 200 C erhitzt, wobei man durch einen Stickstoffstrom das bei der Veresterung freiwerdende Wasser aus dem Reaktionsgefäss entfernt. Es bildet sich ein wasserlösliches farbloses Produkt von gutem Wasch-, Reinigungs- und Dispergier- vermögen, das zum Beispiel auch als Weich- machungsmittel für Kunstseide verwendbar ist.
<B> Additional patent </B> to main patent No. 154507. Process for the production of a wetting agent, cleaning agent, emulsifying agent. suitable product. The main application describes a process for the preparation of a product suitable as a wetting agent, cleaning agent, emulsifier, etc., in which sulfoacetic acid is esterified in the carboxyl group with oleic alcohol.
It has now been found that a valuable product is obtained in a completely analogous manner if sulfoacetic acid in the carboxyl group is esterified with octodecyl alcohol. The octodecyl alcohol can be obtained, for example, by reducing oleic or stearic acid or their esters. The octodecyl alcohol can also be obtained by reducing animal or vegetable oils or fats, such as soybean oil, peanut oil, etc.
The esterification can take place in the usual way. It is expedient to heat the sulfoacetic acid with octodecyl alcohol to about 100 ° C., whereby it is advantageous to remove the water released during the esterification by applying a vacuum.
Instead of the free sulfoacetic acid, you can also use the monoalkali salt, for example the monosodium salt, which is easily obtained by neutralizing the aqueous solution of sulfoacetic acid with sodium hydroxide until the Congo acidic reaction disappears, with one equivalent of alkali, based on the sulfo group, is consumed. If the sodium salt obtained in this way is heated to about 180 ° C. with the equivalent amount of octodecyl alcohol, esterification occurs.
Instead of sulfoacetic acid, derivatives of sulfoacetic acid, for example the esters or halides, can also be used.
The compound produced in the manner described is a colorless product and, like the product obtained by the process of the main application, is particularly suitable as a detergent, emulsifier, wetting agent, etc. and can be used in many ways, especially in the textile industry Find.
<I> Example: </I> 162 parts of 1> ionosodium salt of sulfoacetic acid are heated with 270 parts of octodecyl alcohol to 200 ° C. for 8 hours with stirring, the water released during the esterification being removed from the reaction vessel by a stream of nitrogen away. A water-soluble, colorless product with good washing, cleaning and dispersing properties is formed, which can also be used, for example, as a plasticizer for rayon.
