Description

Wasch- und Reinigungsmittel Es ist bekannt, für Wasch- und Reinigungszwecke, insbesondere für Textilien, die Schwefelsäureester oder Orthophosphorsäureester der hochmolekularen aliphatischen Alkohole bzw. deren Alkalisalze zu verwenden.Detergents and cleaning agents It is known for washing and cleaning purposes especially for textiles containing sulfuric acid esters or orthophosphoric acid esters to use the high molecular weight aliphatic alcohols or their alkali salts.

Es wurde nun gefunden, daß die Alkalisalze der sauren Pyrophosphorsäureester der höher molekularen aliphatischen Alkohole, die man z. B. durch Umsetzung von Pyrophosphorsäure mit den höheren Alkoholen und Neutralisation erhalten hat, ein noch wesentlich besseres Waschvermögen besitzen als die besten bisher bekannten synthetischen Waschmittel, die Fettalkoholsulfonate. Wäscht man bei gleichen Bedingungen in bezug auf Konzentration, Temperatur und PH-Wert einmal mit dem Alkalisalz des sauren Pyrophosphorsäureesters und einmal mit dem Alkalisalz des Schwefelsäureesters, so ist der Wascheffekt, der am besten durch Aufhellung einer Standardanschmutzung dokumentiert werden kann, im ersten Falle wesentlich besser.It has now been found that the alkali salts of the acidic pyrophosphoric acid esters the higher molecular weight aliphatic alcohols, which are z. B. by implementing Pyrophosphoric acid obtained with the higher alcohols and neutralization have much better washing power than the best known so far synthetic detergents containing fatty alcohol sulfonates. One washes under the same conditions Concentration, temperature and pH value once with the alkali salt des acidic pyrophosphoric acid ester and once with the alkali salt of sulfuric acid ester, so is the washing effect, which is best achieved by lightening a standard soiling can be documented, in the first case much better.

Die neuen Waschmittel können in folgender Weise hergestellt werden: i. .too g Kokosfettalkohol werden auf 9o° erwärmt und in i8o g ebenfalls auf 9o° erwärmte Pyrophosphorsäure eingerührt. Die Temperatur steigt dabei auf i io°, und es entsteht eine violettbraune sirupöse Masse, welche unter Kühlung in 8o g Ätznatron 300 ccm Wasser eingerührt und neutralisiert wird. Die erhaltene homogene gelblichweiße Paste ist fast vollständig alkohollöslich. Das umkristallisierte getrocknete Produkt hat einen Gehalt von 64,3 % Fettalkohol.The new detergents can be prepared in the following ways: i. .too g of coconut fatty alcohol are heated to 90 ° and stirred into 18o g of pyrophosphoric acid, also heated to 90 °. The temperature rises to 10 °, and a violet-brown syrupy mass is formed which, while cooling, is stirred into 80 g of caustic soda, 300 cc of water, and neutralized. The homogeneous yellowish-white paste obtained is almost completely soluble in alcohol. The recrystallized, dried product has a fatty alcohol content of 64.3%.

2. Zoo g Kokosfettalkohol werden auf 9o° erwärmt und in 540 g auf 95° erwärmte Pyrophosphorsäure eingerührt. Die Temperatur steigt dabei auf iio°. Nach dem Erkalten wird mit 36o g Ätznatron iooo.ccm Wasser unter Kühlung neutralisiert. Der entstandene Pyrophosphorsäureester wird ausgeschieden. Die, Paste trennt sich in zwei Schichten. Das Wasser wird abgegossien und die gelblich- _ weiße Paste wiederholt mit heißem Alkohol extrahiert. Es ist ganz wenig alkohollöslicher Ester entstanden. Der mit Äther gereinigte und getrocknete Rückstand enthält 2.1. °/o Fettalkohol und ist leicht wasserlöslich.2. Zoo g of coconut fatty alcohol are heated to 90 ° and in 540 g 95 ° warmed pyrophosphoric acid stirred in. The temperature rises to 10 °. After cooling, it is neutralized with 36o g of caustic soda 100o.ccm water while cooling. The resulting pyrophosphoric acid ester is excreted. The, paste separates in two layers. The water is poured off and the yellowish-white paste is repeated extracted with hot alcohol. Very little alcohol-soluble ester was formed. The residue, cleaned with ether and dried, contains 2.1. ° / o fatty alcohol and is easily soluble in water.

3. 5-.o g auf 9o° erwärmter gehärteter Spermölalkohol, verestert mit i8o g Pyrophosphorsäure, ergibt ein Produkt von 8o °/o Fettalkoholgehalt, welches warm wasserlöslich ist.3. 5-o g hardened sperm oil alcohol heated to 90 °, esterified with 18o g of pyrophosphoric acid gives a product with 80 per cent fatty alcohol content, which is warm water soluble.

.4. 270 g gehärteter Spermölalkohol werden auf 9o° erwärmt und mit 54o g Pyrophosphorsäure verestert und wie oben neutralisiert. Das reine getrocknete Produkt enthält 25,7)/, Fettalkohol..4. 270 g of hardened sperm oil alcohol are heated to 90 ° and esterified with 54o g of pyrophosphoric acid and neutralized as above. The pure dried product contains 25.7) /, fatty alcohol.
