Description
Verfahren zur Darstellung eines quaternären Aminobenzylacylamins. Es wurde gefunden, dass durch Umsetzung von Aminobenzyl-aminoarylverbindungen mit nicht aromatischen Carbonsäureamiden in ein- facher und glatter Reaktion bisher nicht be schriebene Aminobenzylacylamine erhalten werden können.
Diese Reaktion geht nach folgendem allgemeinen Schema vor sich
EMI0001.0007
Dabei bedeuten: R # CO- den Acylrest einer höher mole kularen, aliphatischen oder alicyclischen, mehr als 5 C-Atome enthaltenden Fettsäure, die zudem gesättigt oder ungesättigt, substituiert oder unsubstituiert sein kann, R' R" Alkyl-, Cycloalkyl- oder Aralkyl- radikale, die gleich oder verschieden sein dür fen und wovon eines auch Wasserstoff sein darf.
Die als Ausgangsmaterial verwendeten Aminobenzyl-aminoarylverbindungen werden allgemein dargestellt durch Umsetzung von primären Aminoverbindungen, die mit Form aldehyd keine oder wenigstens keine beständi gen Anhydroverbindungen bilden, wie z. B.
p-Toluidin, Sulfanilsäure, ihre Isomeren urrd Ho mologen, Aminonaphthalinsulfonsäuren <B>USW.</B> mit Formaldehyd oder wie diese reagierenden Stoffen und sekundären und tertiären aroma tischen Aminen mit freier p-Stellung, welche die oben angegebenen N-Substituenten R' und R" enthalten.
Solche Verbindungen, zum Beispiel die- jenige aus Sulfanilsäure, Formaldehyd und Dimethylanilin finden sich in der deutschen Patentschrift Nr. 116959 beschrieben, nach deren Verfahren diese Verbindungen mit aro matischen Aminen mit freier p-Stellung zu Diphenylmethanderivaten umgesetzt werden. Dabei kommt es zu einer neuen C-C-Bindung des Methankohlenstoffatomes mit einem Koh- lenstoffatom des Benzolringes des aromatischen Amins.
Nach der oben beschriebenen neuen Ar beitsweise dagegen tritt überraschenderweise eine Umsetzung dieser Aminobenzyl-amino- arylverbindungen mit dem N-Atom des nicht aromatischen Carbonsäureamides unter Bil dung einer neuen durchaus stabilen C-N-Bin- dung ein. Damit ist ein interessantes, glatt verlaufendes neues Verfahren zur Darstellung von p-Aminobenzylaminderivaten gefunden worden.
Durch Behandlung nach üblichen Verfah ren mit unsubstituierten oder durch Halogen und/oder Hydrogylgruppen substituierten Al- kylierungsmitteln lassen sich die erhaltenen Aminobenzylacylamine in die quaternären Verbindungen überführen, wodurch neue und wertvolle Netz-, Dispergier- und Emulgier- mittel, insbesondere aber Weichmachungsmit- tel für Baumwolle oder umgefällte Zellulose erhalten werden.
Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung der Verbindung der Formel
EMI0002.0029
gekennzeichnet durch Umsetzung von Stearin- säureamid mit p-Dimethylaminobenzylsulfanil- säure zum p-Dimethylaminostearoylbenzyl- amin und Umwandlung dieses Acylamines mit Diäthylsulfat in die entsprechende qua- ternäre Verbindung.
Die neue Verbindung wird als weiche Masse erhalten, die sich leicht in Wasser löst und wertvolle kapillaraktive Eigenscbaf- ten besitzt. Sie eignet sich insbesondere als Weichmacher für Baumwolle und umgefällte Zellulose.
Beispiel: 1 Mol. Stearinsäureamid und 1,1 Mol p Dimethylamino-benzylsulfanilsäure werden in ammoniakalischer Lösung 6 Stunden im Rühr- autoklaven auf 150 C erhitzt. Nach dem Erkalten wird die Reaktionsmasse abgesaugt und mit Wasser nachgewaschen.
Darauf wird das Produkt zur Reinigung in heissem Amyl- alkohol aufgenommen, das Wasser abgetrennt und die amylalkoholische Lösung vom Un gelösten abfiltriert. Nach dem Abdestillieren des Lösungsmittels erhält man das sub8ti- tuierte Fettsäureamid als hellbraune wachs artige Masse.
Durch zweistündiges Erwärmen mit der gleichen Gewichtsmenge<B>an</B> Diäthylsulfat er hält man die quaternäre Ammoniumverbin- dung als weiche Masse, die sich leicht in Wasser löst und wertvolle kapillaraktive Ei genschaften besitzt. Sie eignet sich insbeson dere als Weichmacher für Baumwolle und umgefällte Zellulose.
Process for the preparation of a quaternary aminobenzylacylamine. It has been found that by reacting aminobenzyl-aminoaryl compounds with non-aromatic carboxamides in a simple and smooth reaction, aminobenzylacylamines not previously described can be obtained.
This reaction proceeds according to the following general scheme
EMI0001.0007
Here: R # CO- denote the acyl radical of a higher molecular, aliphatic or alicyclic fatty acid containing more than 5 carbon atoms, which can also be saturated or unsaturated, substituted or unsubstituted, R 'R "alkyl, cycloalkyl or aralkyl - radicals that can be the same or different, one of which can also be hydrogen.
The aminobenzyl-aminoaryl compounds used as starting material are generally represented by reacting primary amino compounds that form no or at least no stable anhydro compounds with formaldehyde, such as. B.
p-Toluidine, sulfanilic acid, its isomers and homologues, aminonaphthalenesulfonic acids <B> ETC. </B> with formaldehyde or substances that react like these and secondary and tertiary aromatic amines with a free p-position which contain the above-mentioned N-substituents R. 'and R "included.
Such compounds, for example those made from sulfanilic acid, formaldehyde and dimethylaniline, are described in German Patent No. 116959, according to whose process these compounds are reacted with aromatic amines with a free p-position to give diphenylmethane derivatives. This leads to a new C-C bond between the methane carbon atom and a carbon atom on the benzene ring of the aromatic amine.
According to the new procedure described above, however, a reaction of these aminobenzyl-amino-aryl compounds with the N atom of the non-aromatic carboxamide surprisingly occurs, with the formation of a new, thoroughly stable C-N bond. An interesting, smoothly running new process for the preparation of p-aminobenzylamine derivatives has thus been found.
The aminobenzylacylamines obtained can be converted into the quaternary compounds by treatment by customary methods with unsubstituted or halogen and / or hydrogyl-substituted alkylating agents, thereby creating new and valuable wetting, dispersing and emulsifying agents, but especially plasticizers for Cotton or reprecipitated cellulose can be obtained.
The present patent relates to a process for the preparation of the compound of the formula
EMI0002.0029
characterized by the reaction of stearic acid amide with p-dimethylaminobenzylsulfanilic acid to give p-dimethylaminostearoylbenzylamine and conversion of this acylamine with diethyl sulfate into the corresponding quaternary compound.
The new compound is obtained as a soft mass that dissolves easily in water and has valuable capillary-active properties. It is particularly suitable as a softener for cotton and reprecipitated cellulose.
Example: 1 mol. Of stearic acid amide and 1.1 mol of p-dimethylaminobenzylsulphanilic acid are heated to 150 ° C. in an ammoniacal solution for 6 hours in a stirred autoclave. After cooling, the reaction mass is filtered off with suction and washed with water.
The product is then taken up in hot amyl alcohol for cleaning, the water is separated off and the undissolved amyl alcoholic solution is filtered off. After the solvent has been distilled off, the substituted fatty acid amide is obtained as a light brown, wax-like mass.
By heating for two hours with the same amount of diethyl sulfate by weight, the quaternary ammonium compound is kept as a soft mass that dissolves easily in water and has valuable capillary-active properties. It is particularly suitable as a softener for cotton and reprecipitated cellulose.
