Description
Verfahren zur Herstellung eines Netz-, Dispergier-, Emulgier- und Waschmittels. Es wurde gefunden, dass man zu einem neuen, wertvollen Netz-, Dispergier-, Emul- gier- und Waschmittel gelangen kann,
wenn man das durch Reduktion der Ester der Kokos- oder Palmkernfettsäure erhältliche Fettalkoholgemisch mit Chloressigsäure ver- estert und dieses Estergemisch mit wasser löslichen Salzen der hydroschwefligen Säure umsetzt.
Der entstandene neue Körper stellt in reiner Form ein weisses, kristallinisches Pul ver dar, das in Wasser leicht löslich ist, Fehlingsche Lösung reduziert und sich als vorzügliches Netz- und Waschmittel eignet. Die von einem solchen Tegtilhilfsprodukt heute geforderten Echtheiten werden erfüllt.
<I>Beispiel:</I> 200 Teile des im Handel befindlichen, durch Reduktion der Palmkern- oder Kokos- fettsäureester erhältlichen Fettalkoholgemi- sches und 120 Teile Chloressigsäure werden mit Hilfe von Salzsäuregas verestert und hierauf unter starkem Rühren mit der Tur bine einer Lösung von 250 Teilen Natrium hydrosulfit 85 % in 900 Teilen Wasser zu gegeben und 12 Stunden unter Rückfluss ge- kocht.
Ist die Umsetzung beendet und der Gefässinhalt erkaltet, so scheidet sich ein Teil des neuen Produktes in halbfester Form aus.
Dasselbe löst sich in Wasser klar und unter intensiver Schaumbildung und zeigt alle von einem guten Waschmittel geforder ten Echtheiten.
Process for the production of a wetting, dispersing, emulsifying and washing agent. It has been found that a new, valuable wetting, dispersing, emulsifying and washing agent can be obtained,
when the fatty alcohol mixture obtainable by reducing the esters of coconut or palm kernel fatty acid is esterified with chloroacetic acid and this ester mixture is reacted with water-soluble salts of hydrosulphurous acid.
The resulting new body is in its pure form a white, crystalline powder that is easily soluble in water, reduces Fehling's solution and is suitable as an excellent wetting agent and detergent. The fastness properties required today of such a Tegtil auxiliary product are met.
<I> Example: </I> 200 parts of the commercially available fatty alcohol mixture obtainable by reducing the palm kernel or coconut fatty acid esters and 120 parts of chloroacetic acid are esterified with the aid of hydrochloric acid gas and then a solution with vigorous stirring with the turbine of 250 parts of sodium hydrosulfite 85% in 900 parts of water are added and the mixture is refluxed for 12 hours.
When the reaction has ended and the contents of the vessel have cooled down, part of the new product is deposited in semi-solid form.
The same dissolves in water clearly and with intensive foam formation and shows all the fastness properties required of a good detergent.
