Description
Verfahren zur Herstellung eines Gemisches von Natriumsalzen acylierter Aminomethansulfosäuren. Es wurde gefunden, dass man durch Kon densation von aliphatischen Sulfamiden der allgemeinen Formel RS02NH2 und deren sub- stituierten Produkten mit Formaldehydbisulfit zu Sulfonsäuren gemäss folgender Gleichung gelangt RS02NH2 -+- C1120 - NaHS0s = RS02NH
# CH@SO3Na -f - H20 <I>Die</I> Umsetzung gestattet in sehr einfacher Weise die Herstellung von in der Aminogruppe durch den Sulfonsäurerest acylierten Amino- methansulfönsäuren bezw. deren Salzen.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Gemisches von Natriumsalzen von durch einen Sulfon- säurerest acylierten Aminomethansulfonsäuren, welches dadurch gekennzeichnet ist, dass man Formaldehyd-Natriumbisulfit auf ein Sulfamid- gemisch einwirken lässt, das durch gleichzeitige Einwirkung von Chlor und Schwefeldioxyd auf eine Benzinfraktion mit den Siedegrenzen 230 bis 320 und anschliessende Umsetzung mit Ammoniak erhalten wurde.
Das erhaltene Produkt ist in Wasser löslich und kann als Textilhilfsmittel ver wendet werden.
<I>Beispiel 1:</I> 270 Gewichtsteile eines Sulfamidgemisches, hergestellt durch gleichzeitige Einwirkung von Chlor und Schwefeldioxyd auf eine Benzin fraktion von den Siedegrenzen 230 bis 320 und Behandlung der entstandenen Sulfochloride mit Ammoniak, werden mit einer Lösung von 190 Gewichtsteilen Formaldehyd-Natriumbi- sulfit in 200 Gewichtsteilen Wasser versetzt und mehrere Stunden unter Rückfluss gekocht.
Nachdem darauf alles Wasser abdestilliert und das Produkt kurze Zeit nacherhitzt worden ist, bleibt eine hellbraune, in Wasser lösliche Substanz, deren Lösung gutes Schaumvermögen besitzt, zurück.
Das Produkt kann als Textilhilfsmittel verwendet werden.
<I>Beispiel 2:</I> 270 Gewichtsteile eines Sulfamidgemisches, hergestellt durch gleichzeitige Einwirkung von Chlor und Schwefeldioxyd auf eine Benzin fraktion mit den Siedegrenzen 230 bis 320 und Behandlung der entstandenen Sulfochloride mit Ammoniak, werden unter gutem Rühren mit 190 Gewichtsteilen Formaldehyd-Natrium- bisulfit auf 160 bis 170 erhitzt, bis eine Probe der Substanz löslich geworden ist. Das entstandene hellbraune Produkt ist eine wasser lösliche Substanz, deren Lösungen gutes Schaumvermögen zeigen.
Process for the preparation of a mixture of sodium salts of acylated aminomethanesulfonic acids. It has been found that condensation of aliphatic sulfamides of the general formula RS02NH2 and their substituted products with formaldehyde bisulfite leads to sulfonic acids according to the following equation RS02NH2 - + - C1120 - NaHS0s = RS02NH
# CH @ SO3Na -f - H20 <I> The </I> reaction allows in a very simple manner the production of amino methanesulfonic acids acylated in the amino group by the sulfonic acid residue. their salts.
The subject of the present patent is a process for the preparation of a mixture of sodium salts of aminomethanesulfonic acids acylated by a sulfonic acid residue, which is characterized in that formaldehyde-sodium bisulfite is allowed to act on a sulfamide mixture, which by the simultaneous action of chlorine and sulfur dioxide on a Gasoline fraction with boiling limits 230 to 320 and subsequent reaction with ammonia was obtained.
The product obtained is soluble in water and can be used as a textile auxiliary.
<I> Example 1: </I> 270 parts by weight of a sulfamide mixture, produced by the simultaneous action of chlorine and sulfur dioxide on a gasoline fraction of the boiling limits 230 to 320 and treatment of the resulting sulfochlorides with ammonia, are mixed with a solution of 190 parts by weight of formaldehyde Sodium bisulfite is added to 200 parts by weight of water and the mixture is refluxed for several hours.
After all the water has been distilled off and the product has been reheated for a short time, a light brown, water-soluble substance, the solution of which has good foaming properties, remains.
The product can be used as a textile auxiliary.
<I> Example 2: </I> 270 parts by weight of a sulfamide mixture, produced by the simultaneous action of chlorine and sulfur dioxide on a gasoline fraction with boiling limits 230 to 320 and treatment of the resulting sulfochlorides with ammonia, are mixed with 190 parts by weight of formaldehyde with thorough stirring. Sodium bisulfite heated to 160 to 170 until a sample of the substance has become soluble. The resulting light brown product is a water-soluble substance whose solutions show good foaming properties.
