Description
Verfahren zur Herstellung einer höher molekularen a-substituierten Benzylaminsulfonsäur e. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung einer höher molekularen, a -substituierten Benzylamin- sulfonsäure, dadurch gekennzeichnet, dass man N - Benzyl - N - methyl - co - undecyl - (4 methylbenzyl)-amin sulfiert.
Die neue Sulfonsäure bildet als Natrium salz ein helles Pulver, das sich in Wasser gut löst. Sie kann als Wasch- und Netz- mittel und als galkseifenemulgator Ver wendung finden.
Beispiel: -1/2 Mol N-Benzyl-a-undecyl-(4-methyl- benzyd)-amin, hergestellt nach den Angaben im Zusatzpatent Nr. 211796, löst man in 1000 Teilen trockenem Chlorbenzol und fügt 63 Teile feste Soda hinzu. Unter gutem Rühren werden 65 Teile Dimethylsulfat bei 90-100' zugetropft und 12-15 Stunden bei dieser Temperatur gehalten.
Nach dem Abkühlen wird die Chlorbenzollösung mit Wasser gewaschen, das Lösungsmittel im Vakuum entfernt und die erhaltene tertiäre Base destilliert, Kpo,#- n,", 170-215 .
Das, so erhaltene N-Benzyl-N-methyl-a-unclecyl-(4- methylbenzyl)-amin wird in 110 Teilen Sehwefelsäuremonohydrat bei Zimmertem peratur gelöst, auf 0 abgekühlt, langsam 50 Teile 26%iges Oileum eingetragen und gerührt, bis sich eine Probe in verdünnter I\Tatronlauge klar löst. Man giesst auf 600 Teile Dis und neutralisiert mit Kali lauge. Nach dem Eindampfen und Trocknen erhält man ein helles Pulver, dass sich in Wasser gut löst.
Process for the preparation of a higher molecular weight α-substituted benzylamine sulfonic acid e. The subject of the present patent is a process for the preparation of a higher molecular weight, α-substituted benzylamine sulfonic acid, characterized in that N-benzyl-N-methyl-co-undecyl- (4-methylbenzyl) -amine is sulfated.
As sodium salt, the new sulphonic acid forms a light powder that dissolves well in water. It can be used as a detergent and wetting agent and as a soap emulsifier.
Example: -1/2 mol of N-benzyl-a-undecyl- (4-methylbenzyd) -amine, prepared according to the information in additional patent no. 211796, is dissolved in 1000 parts of dry chlorobenzene and 63 parts of solid soda are added. 65 parts of dimethyl sulfate are added dropwise at 90-100 'with thorough stirring and the mixture is kept at this temperature for 12-15 hours.
After cooling, the chlorobenzene solution is washed with water, the solvent is removed in vacuo and the tertiary base obtained is distilled, Kpo, # - n, ", 170-215.
The N-benzyl-N-methyl-a-unclecyl- (4-methylbenzyl) amine thus obtained is dissolved in 110 parts of sulfuric acid monohydrate at room temperature, cooled to 0, 50 parts of 26% iges oil are slowly added and stirred until a sample clearly dissolves in dilute sodium hydroxide solution. It is poured into 600 parts of Dis and neutralized with potassium hydroxide. After evaporation and drying, a pale powder is obtained that dissolves well in water.
