Abstract

A powder mixture containing zeolite A and trisodium nitrilotriacetate is prepared by spray drying. The resulting powdered product is used as phosphate substitute in detergents.

Description

Phosphatsubstitut für Waschmittel Phosphate substitute for detergents

Die Erfindung betrifft ein pulverförmiges Phosphatsubstitut für Waschmittel.The invention relates to a powdered phosphate substitute for detergents.

Zeolithpulver des Typs A mit einer spezifischen Teilchenverteilung ist ein ausgezeichnetes Phosphatsubstitut in Waschmitteln.Type A zeolite powder with a specific particle distribution is an excellent substitute for phosphate in detergents.

Bei der Herstellung von Waschmitteln durch den Sprühmischprozess treten Schwierigkeiten wegen der Feinteiligkeit des Zeolithpulvers auf. Dieses neigt in Leitungen und Vorratsbehältern zur Brückenbildung.Step through the spray mixing process when making detergents Difficulties due to the fine division of the zeolite powder. This tends in Lines and storage tanks for bridging.

Es ist bekannt zu diesem Zwecke das Zeolithpulver nach Na2 SO4 zu vermischen (DE-OS 27 38 085).For this purpose it is known to use zeolite powder according to Na2 SO4 mix (DE-OS 27 38 085).

Dieses Verfahren ergibt jedoch ein Zeolithpulvergemisch mit (auf die Gesamtmenge bezogen) eingeschränkten Calciumbindevermögen.However, this method results in a zeolite powder mixture with (on the Total amount related) limited calcium binding capacity.

Aufgabe der Erfindung ist es die Rieselfähigkeit des Zeolithpulvers zu verbessern und das Calciumbindevermögen zu erhalten.The object of the invention is the flowability of the zeolite powder to improve and to maintain the calcium binding capacity.

Gegenstand der Erfindung ist ein pulverförmiges Phosphatsubstitut für Waschmittel, enthaltend Zeolith A und Nitrile triessigsäuretrinatriumsalz.The invention relates to a powdered phosphate substitute for detergents containing zeolite A and nitrile triacetic acid trisodium salt.

In einer bevorzugten Aus führungs form enthält das erfindungsgemäße Phosphatsubstitut Zeolith A und Nitriloessigsäure als alleinige Bestandteile.In a preferred embodiment, the inventive contains Phosphate substitute zeolite A and nitriloacetic acid as sole components.

Das pulverförmige Phosphatsubstitut kann Nitrilotriessigsäuretrinatriumsalz in einer Menge von 3 bis 50 Gew,.-%, vorzugsweise 5 bis 50 Gew.-%, bezogen auf Zeolith A, enthalten.The powdery phosphate substitute can be nitrilotriacetic acid trisodium salt in an amount of 3 to 50% by weight, preferably 5 to 50% by weight, based on zeolite A, included.

Als Zeolith A kann insbesondere ein Zeolithpulver des Typs A eingesetzt werden, wie es in den Druckschriften DE-AS 24 47 C DE-AS 25 17 218, DE-OS 26 51 419, DE-OS 26 51 410, DE-OS 26 51 436, DE-OS 26 51 437; DE-OS 26 51 445 und DE-OS 26 51 4 beschrieben wird.A type A zeolite powder can in particular be used as zeolite A as it is in the publications DE-AS 24 47 C DE-AS 25 17 218, DE-OS 26 51 419, DE-OS 26 51 410, DE-OS 26 51 436, DE-OS 26 51 437; DE-OS 26 51 445 and DE-OS 26 51 4 is described.

Das erfindungsgemäße pulverförmige Phosphatsubstitut für Waschmittel kann derart hergestellt werden, daß man eine wässrige Suspension von Zeolith A und Nitrilotriessigsäuretrinatriumsalz vermischt und anschließend spruh..trocknet Die wässrige Suspension des Zeolith A kann Dispergierhilfsmittel, beispielsweise Talgalkohol, enthalten Derartige Suspensionen sind aus der DE-OS 26 15 698 bekannt Das erfindungsgemäße pulverförmige Phosphatsubstitut weist den Vorteil auf, daß es ein gut handhabbares, gut rieselfähiges Pulver darstellt, welches ein unvermindertes Calciumbindevermögen aufweist.The powdery phosphate substitute for detergents according to the invention can be prepared in such a way that an aqueous suspension of zeolite A and Nitrilotriacetic acid trisodium salt mixed and then spray-dried aqueous suspension of zeolite A may contain dispersants, for example tallow alcohol, Such suspensions are known from DE-OS 26 15 698. The inventive powdery phosphate substitute has the advantage that it is an easy to handle, is a free-flowing powder, which has an undiminished calcium binding capacity having.

Beispiel 1 Das Produkt wurde auf dem Technikumssprühturm hergestellt.Example 1 The product was produced on the pilot plant spray tower.

Zur Herstellung des Slurry werden in 40 kg Zeolith A 40-Master-batch, welches Talgalkohol enthält, 1,8 kg Nitrilotriessigsäuretrinatriumsalz (NTA Na3) eingerührt. Das entspricht einem Nitrilotriessigsäure-Gehalt von ca. 10 % bezogen auf Zeolith A atro. Die Slurry-Konzentration stieg dabei von 44 auf 46 t.To produce the slurry, 40 kg of zeolite A 40 master batch, which contains tallow alcohol, 1.8 kg nitrilotriacetic acid trisodium salt (NTA Na3) stirred in. This corresponds to a nitrilotriacetic acid content of approx. 10% on zeolite A atro. The slurry concentration rose from 44 to 46 t.

Es wurde auf 40 8 Feststoffgehalt verdünnt.It was diluted to a solids content of 40 8.

Es ist ein weißes Pulver, das bessere Fließeigenschaften als reiner Zeolith A besitzt.It is a white powder that has better flow properties than pure Zeolite A possesses.
