Description
Verfahren zur Herstellung eines Gemisches von quaternären Ammoniumverbindungen. Es wurde gefunden, dass man ein Gemisch von quaternären Ammoniumverbindungen er hält, wenn man auf je ein Mol eines Ge misches der Sulfate der tertiären Dimethyl- amine, die als dritten N-Substituenten die höhermolekularen Alkylreste enthalten, die in den durch Reduktion der Palmkernfett- säuren erhältlichen Alkoholen vorkommen,
etwa ein Mol Äthylenoxyd unter erhöhtem Druck bei Temperaturen bis zu<B>1000</B> C ein wirken lässt.
Die Reaktion kann in Abwesenheit von Wasser ausgeführt werden, wodurch in einem Arbeitsgang das Gemisch der wasserfreien quaternären Salze in glatter Reaktion erhalten wird. Beispielsweise bildet sich dieses Gemisch quaternärer Salze bereits beim Erhitzen der genannten Ausgangsstoffe unter Druck auf 50-100 C in kurzer Zeit. Man kann die Reaktion jedoch auch in Gegenwart von Wasser ausführen. Im allgemeinen arbeitet man unter dem Druck, der sich beim Arbeiten im geschlossenen Reaktionsgefäss unter den Reaktionsbeding ungen einstellt. Man kann jedoch auch den Druck durch Aufpressen von inerten Gasen, z. B. von Stickstoff, noch erhöhen.
Das Endprodukt, aus dem das Basen gemisch in Freiheit gesetzt werden kann, ist beispielsweise als wertvolles Hilfsmittel für die Textilindustrie und verwandte Ge biete, als Farbstoffzwischenprodukt oder für pharmazeutische Zwecke verwendbar.
Die in dem folgenden Beispiel angegebenen Teile sind Gewichtsteile. <I>Beispiel:</I> 245 Teile eines Gemisches der tertiären Dimetbylamine, die als dritten N-Substituen- ten die höhermolekularen Alkylreste ent halten, die in den durch Reaktion der Palm kernfettsäuren erhältlichen Alkoholen vor- kommen, werden mit 500 Teilen Wasser ver rührt und mit 200 Teilen 25o/oiger Schwefel säure neutralisiert. Man erhitzt die erhaltene Lösung im Druckgefäss mit 50 Teilen Äthylen ogyd auf 90-100' C.
Nach einer Stunde ist alles Äthylenogyd aufgenommen.<B>Man</B> er hält 1000 Teile einer etwa 34o/oigen Lösung eines Gemisches quaternärer Ammoniumsul- fate, die je zwei Methylgruppen, eine Äthanol- gruppe und eine höhermolekulare Alkylgruppe der oben angegebenen Art enthalten. Durch Eindampfen erhält man das Gemisch dieser quaternären Salze als farblose Masse von sirupartiger Beschaffenheit.
Process for the preparation of a mixture of quaternary ammonium compounds. It has been found that a mixture of quaternary ammonium compounds is obtained if one mole of a mixture of the sulfates of the tertiary dimethyl amines, which contain the higher molecular weight alkyl radicals as the third N-substituents, which are in the by reduction of the palm kernel fat acids available alcohols occur,
about one mole of ethylene oxide can act under increased pressure at temperatures up to <B> 1000 </B> C.
The reaction can be carried out in the absence of water, whereby the mixture of the anhydrous quaternary salts is obtained in a smooth reaction in one operation. For example, this mixture of quaternary salts is formed in a short time when the starting materials mentioned are heated to 50-100 ° C. under pressure. However, the reaction can also be carried out in the presence of water. In general, one works under the pressure which is established when working in a closed reaction vessel under the reaction conditions. However, you can also increase the pressure by forcing inert gases such. B. of nitrogen, still increase.
The end product, from which the base mixture can be set free, can be used, for example, as a valuable aid for the textile industry and related fields, as an intermediate dye product or for pharmaceutical purposes.
The parts given in the following example are parts by weight. <I> Example: </I> 245 parts of a mixture of the tertiary dimethylamines, which contain the higher molecular weight alkyl radicals as third N-substituents, which occur in the alcohols obtainable by reaction of the palm kernel fatty acids, are mixed with 500 parts of water stirred ver and neutralized with 200 parts of 25% sulfuric acid. The solution obtained is heated to 90-100 ° C. in a pressure vessel with 50 parts of ethylene oxide.
After one hour, all of the ethylene oxide is absorbed. <B> You </B> hold 1000 parts of an approximately 34% solution of a mixture of quaternary ammonium sulphates, each containing two methyl groups, one ethanol group and one higher molecular weight alkyl group of the type specified above contain. The mixture of these quaternary salts is obtained as a colorless mass of syrupy consistency by evaporation.
