Description
Verfahren zur Herstellung einer höher molekularen a-substituierten Benzylaminsulfonsäure. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung einer höher molekularen a-substituierten Benzylaminsul- fonsäure, dadurch gekennzeichnet, dass man a,-IIeptadecylbenzyl-dimethylamin sulfiert.
Die neue Sulfonsäure bildet als Natrium salz ein hellgelbes Pulver, dessen wässrige Lösungen schwach schäumen. Sie kann als Wasch- und Netzmittel und als Kalkseifen emulgator Verwendung finden.
<I>Beispiel:</I> 1 Mol Stearoylbenzol wird in alkoholi schem AmmonialL (dreifachem Überschuss) gelöst und im Autoklaven bei 80 bis 90 und <B>1.10</B> Alm. katalytisch hydriert. Nach dem Abfiltrieren des Katalysators und Abdamp fen des Alkohols wird das rohe a-Hepta- decylbenzylamin im Vakuum destilliert, Kpo.e mm 210 bis 212 .
In 800 Teilen trockenem Chlorbenzol wird Mol a-IIeptadecyl-benzylamin gelöst, 60 Teile feste Soda zugesetzt und bei 90 bis <B>100'</B> langsam 65 Teile Dimethylsulfat ein getropft. Nach 12 Stunden wird das Ganze mit dem gleichen Volumen Wasser vermengt und das Lösungsmittel mit Wasserdampf ab getrieben. Durch Ausäthern des Rückstandes und nachfolgende Vakuumdestillation ge winnt man das reine a-Heptadecylbenzyldi- methylamin, gp"5 m. 223 .
0,1 Mol a-Heptadecylbenzyldimethylamin löst man in 100 Teilen Schwefelsäuremono- hydrat und lässt bei Zimmertemperatur 50 Teile 26 %iges Oleum zutropfen. Man rührt so lange, bis sich eine Probe des Sul- furationsgemisches in verdünnter Lauge klar löst, giesst auf 600 Teile Eis, neutralisiert mit Natronlauge und gewinnt das Natrium- salz der Sulfonsäure durch Eindampfen.
Es stellt ein hellgelbes Pulver dar, dessen wäss- rige Lösungen schwach schäumen.
Process for the preparation of a higher molecular weight α-substituted benzylamine sulfonic acid. The present patent relates to a process for the preparation of a higher molecular weight α-substituted benzylamine sulphonic acid, characterized in that α, -IIeptadecylbenzyl-dimethylamine is sulphated.
The new sulfonic acid forms a pale yellow powder as sodium salt, the aqueous solutions of which foam slightly. It can be used as a detergent and wetting agent and as a lime soap emulsifier.
<I> Example: </I> 1 mol of stearoylbenzene is dissolved in alcoholic ammonia (three-fold excess) and catalytically hydrogenated in the autoclave at 80 to 90 and <B> 1.10 </B> Alm. After the catalyst has been filtered off and the alcohol is evaporated, the crude α-heptadecylbenzylamine is distilled in vacuo, Kpo.e mm 210 to 212.
Mol a-IIeptadecylbenzylamine is dissolved in 800 parts of dry chlorobenzene, 60 parts of solid soda are added and 65 parts of dimethyl sulfate are slowly added dropwise at 90 to 100 parts. After 12 hours, the whole thing is mixed with the same volume of water and the solvent is driven off with steam. The pure α-heptadecylbenzyldimethylamine, gp "5 m. 223, is obtained by etherifying the residue and subsequent vacuum distillation.
0.1 mol of α-heptadecylbenzyldimethylamine is dissolved in 100 parts of sulfuric acid monohydrate and 50 parts of 26% strength oleum are added dropwise at room temperature. The mixture is stirred until a sample of the sulphuration mixture dissolves clearly in dilute lye, poured onto 600 parts of ice, neutralized with sodium hydroxide solution and the sodium salt of the sulphonic acid is obtained by evaporation.
It is a light yellow powder, the aqueous solutions of which foam slightly.
