Description
Verfahren zur Herstellung eines wasserlöslichen Salzes des Sulfopropion säure-di (2-äthyl-n-hexyl)-amids.
Im Hauptpatent wurde ein Verfahren zur Herstellung eines wasserlöslichen Salzes des Sulfoessigsäure-di (2-äthyl-n-hexyl)-amids be schrieben, wobei eine HalogenessigsÏure bzw. ein funktionelles Derivat einer solchen durch Umsetzung mit Di-(2-Ïthyl-n-hexyl)-amin in das HalogenessigsÏure-di(2-Ïthyl-n-hexyl)amid bergef hrt wird und dann im genannten. Zwischenprodukt dureh Behandlung mit Natriumsulfit das Halogenatom dureh die NaSOg-Gruppe ersetzt wird unter Bildung des Natriumsalzes des Sulfoessigsäure-di (2- äthyl-n-hexyl)-amids.
Wird, wie nun gefunden wurde, an Stelle von Halogenessigsäure die ungesättigte Acrylsäure bzw. ein funktionelles Derivat der sogenannten ungesättigten SÏure, z. B. Acryl- säurechlorid, verwendet, so erhÏlt man das AcrylsÏure-di(2-Ïthyl-n-hexyl)-amid als Zwi. schenprodukt, welches durch Behandlung mit Natriumbisulfit unter Absättigung der Doppelbindung durch Anlagerung von NaSO3H das Natriumsalz des SulfopropionsÏure-di(2-Ïthyln-hexyl)-amids liefert. Diese leicht in Wasser und organischen Lösungsmitteln losliche neue, n'allertartige Substanz ist ein ausgezeichnetes Netz und Dispersionsmittel, ferne-r ein wirksames Spaltmittel f r Erdolemulsionen.
Die Umsetzung des vorzugsweise als funk tionelles Derivat der Acrylsäure verwendeten Acrylsäureehlorids mit dem Amin wird zweck- mässig in einem organischen Lösungsmittel durchgef hrt, z. B. einer Mischung von Dimethylanilin und Toluol. Als Stabilisierungs- rnittel kann Hydroehinon dienen.
Beispiel:
Zu einer Mischung von 146 g Di-(2-Ïthyln-hexyl)-amin, 77 g Dimethylanilin und 250 g Toluol lässt man unter Rühren bei einer Tem peratur unter 10 C 55 g Acrylsäurechlorid, die mit 0, 3 g Hydrochinon stabilisiert wurden, fliessen Das Reaktionagemiseh wird einige Zeit bei Zimmertemperatur stehengelassen und dann abfiltriert. Der Filterrückstand wird mit Toluol ausgewaschen, die Filtra. te gereinigt und durch Zusatz von verdünnter Salzsäure die Losung kongosauer eingestellt.
Von den gebildeten zwei Schichten wird die untere wϯrige Schicht abgetrennt und die obere Schicht mit Wasser säurefrei gewaschen.
Sodann wird das Lösungsmittel abdestilliert bei vermindertem Druck, und als Rückstand werden 150 g des Amids erhalten.
59 g des erhaltenen Acrylsäure-di (2-äthyl n-hexyl)-amids werden in 240 g Alkohol gel¯st und die Losung mit 0, 3 g Hydrochinon versetzt. Die stabilisierte Lösung des Amids wird mit einer Lösung von 24 g Natriumbisulfit in 254 cm3 3 Wasser versetzt und das Gemisch in einem Rührautoklaven auf 100 bis 105 C so lange erhitzt, bis eine klare Lösung entsta. nden ist. Dann wird das Lösungsmittel abdestilliert und der Riiekstand zwecks Ent fernung des freien Natriumbisulfits mit Me thanol aufgenommen und die Losung filtriert.
Durch Abdestillieren des Methanols bei vermindertem Druck werden als Rückstand 70 g des rohen Natriumsalzes des Sulfopropion- sÏure-di (2-äthyl-n-hexyl)-amids erhalten, wel- ches sieh sehr gut als Spalter fiir Wasser-in Íl-Emulsionen eignet.
Process for the preparation of a water-soluble salt of sulfopropionic acid di (2-ethyl-n-hexyl) amide.
In the main patent, a process for the preparation of a water-soluble salt of sulfoacetic acid-di (2-ethyl-n-hexyl) -amide was described, a haloacetic acid or a functional derivative of such by reaction with di- (2-Ïthyl-n- hexyl) amine is converted into the haloacetic acid di (2-ethyl-n-hexyl) amide and then in the above. Intermediate product by treatment with sodium sulfite the halogen atom is replaced by the NaSOg group to form the sodium salt of sulfoacetic acid di (2-ethyl-n-hexyl) amide.
If, as has now been found, instead of haloacetic acid, the unsaturated acrylic acid or a functional derivative of the so-called unsaturated acid, e.g. B. Acrylic acid chloride is used, the acrylic acid-di (2-ethyl-n-hexyl) -amide is obtained as intermediate. This product, which by treatment with sodium bisulfite with saturation of the double bond by addition of NaSO3H, gives the sodium salt of sulfopropionic acid di (2-ethyln-hexyl) amide. This new allergy-like substance, which is easily soluble in water and organic solvents, is an excellent wetting agent and dispersing agent, and also an effective breaking agent for petroleum emulsions.
The reaction of the acrylic acid chloride, which is preferably used as a functional derivative of acrylic acid, with the amine is expediently carried out in an organic solvent, e.g. B. a mixture of dimethylaniline and toluene. Hydroehinone can serve as a stabilizing agent.
Example:
To a mixture of 146 g of di- (2-ethyln-hexyl) amine, 77 g of dimethylaniline and 250 g of toluene, 55 g of acrylic acid chloride, which have been stabilized with 0.3 g of hydroquinone, are added at a temperature below 10 ° C. The reaction agent is left to stand for some time at room temperature and then filtered off. The filter residue is washed out with toluene, the Filtra. The solution was purified and made Congo acidic by adding dilute hydrochloric acid.
The lower aqueous layer is separated from the two layers formed and the upper layer is washed acid-free with water.
The solvent is then distilled off under reduced pressure and 150 g of the amide are obtained as a residue.
59 g of the resulting acrylic acid di (2-ethyl n-hexyl) amide are dissolved in 240 g of alcohol and 0.3 g of hydroquinone are added to the solution. The stabilized solution of the amide is mixed with a solution of 24 g of sodium bisulfite in 254 cm3 3 of water and the mixture is heated in a stirred autoclave to 100 to 105 ° C. until a clear solution is formed. is. The solvent is then distilled off and the residue is taken up with methanol for the purpose of removing the free sodium bisulfite and the solution is filtered.
By distilling off the methanol under reduced pressure, 70 g of the crude sodium salt of sulfopropionic acid di (2-ethyl-n-hexyl) amide are obtained as residue, which is very suitable as a breaker for water-in-oil emulsions .
