Description

Seifenfreie Waschmittel Es wurde gefunden, daß Mischungen aus wasserlöslichen Cellulos.e:alkyläthern, die im Alkylrest eine endständige Sulfonsäuregruppe enthalten, und Alkalisalzen von Naphthalinsulfonsäuren ausgezeichnet als Waschmittel brauchbar sind. Man verwendet die sulfonsäuregruppenhaltigen Cellulosealkyläther vorteilhaft in Form ihrer Alkalisalze. Besonders gut sind .die Alkalisalze der Celluloseäthyläther-ß'-sulfonsäure geeignet. Es können auch Mischäther der Cellulose verwendet werden, die neben den sulfonsäuregruppenhaltigen Alkylresten noch unsubstituierte oder in anderer Weise substituierte Alkylreste, wie Methyl- oder Oxäthylgruppen,enthalten.Soap-free detergents It has been found that mixtures of water-soluble Cellulos.e: alkyl ethers which contain a terminal sulfonic acid group in the alkyl radical, and alkali salts of naphthalenesulfonic acids are excellent as detergents are. The cellulose alkyl ethers containing sulfonic acid groups are advantageously used in the form of their alkali salts. The alkali salts of cellulose ethyl ether-ß'-sulfonic acid are particularly good suitable. It can also be used mixed ethers of cellulose, which in addition to the sulfonic acid group-containing alkyl radicals or unsubstituted or otherwise substituted alkyl radicals such as methyl or oxethyl groups contain.

Als Naphthalinsulfonsäuren eignen sich insbesondere Alkylnaphthalinsulfonsäuren. Geeignete Produkte sind beispielsweise dimethylnaphthalinsulfonsaures Natrium, dibutylnaphthalinsulfonsaures Natrium oder dinonylnaphthalinsulfonsaures Natrium. Auch aralkylnaphthalinsulfonsaure Salze können benutzt werden.Particularly suitable naphthalenesulphonic acids are alkylnaphthalenesulphonic acids. Suitable products are, for example, sodium dimethylnaphthalenesulphonic acid and dibutylnaphthalenesulphonic acid Sodium or sodium dinonylnaphthalenesulfonic acid. Also aralkylnaphthalenesulfonic acid Salts can be used.

-Die Waschmittel gemäß der Erfindung besitzen eine gute Schaum- und Reinigungskraft. Die neuen Waschmittel können infolge ihrer Neutralität bei den verschiedensten Waschvorgängen verwende', werden: Sauerstoffabgebende Salze können ihnen ohne die Gefahr eines Zerfalles zugesetzt werden. Außerdem kann man sie im Gemisch mit anderen üblichen Waschmittelzusätzen verwenden. Die neuen Waschmittel eignen sich besonders gut für die Baumwollwäsche.-The detergents according to the invention have a good foam and Cleaning person. The new detergents can be due to their neutrality with the various washing processes are used: Oxygen-releasing salts can be added to them without the risk of disintegration. You can also use them in Use a mixture with other common detergent additives. The new detergents are particularly suitable for cotton laundry.

Waschmittel, die neben Alkalisalzen von Alkylnaphthalinsulfonsäuren Methyleellulose enthalten, sind bekannt. Die Waschmittel gemäß der Erfindung sind aber wirksamer als die bekannten Waschmittel, insbesondere dann, wenn mit heißen Flotten gewaschen wird. Beispiele i. 5 Teile eines wasserlöslichen Celluloseäthers, der durch Umsetzung von i Mol Alkalicellulose mit 0,5 Mol Äthylenoxyd und i Mol Chloräthansulfonsäure erhalten worden ist, werden mit 3 Teilen Soda und 5 Teilen dibutylnaphthalinsulfonsaurem Natrium in i ooo Teilen Wasser gel'o'st. Die so erhaltene Waschlauge eignet sieh besonders gut zum Reinigen von Leinen oder Baumwolle. Man wäscht damit- zweckmäßig bei höherer Temperatur, beispielsweise bei 9o'. Läßt man bei obiger Zusammensetzung das VZasser fort und stellt in geeigneter Weise eine innige Mischung der anderen Anteile her, so erhält man ein ausgezeichnetes Waschpulver.Detergents which contain methyl cellulose in addition to alkali salts of alkylnaphthalenesulfonic acids are known. However, the detergents according to the invention are more effective than the known detergents, especially when washing is carried out with hot liquors. Examples i. 5 parts of a water-soluble cellulose ether obtained by reacting 1 mole of alkali cellulose with 0.5 mole of ethylene oxide and 1 mole of chloroethane sulfonic acid are dissolved in 3 parts of sodium carbonate and 5 parts of sodium dibutylnaphthalenesulfonate in 1,000 parts of water. The washing liquor obtained in this way is particularly suitable for cleaning linen or cotton. It is advisable to wash it at a higher temperature, for example at 90 '. If the VZasser is omitted from the above composition and an intimate mixture of the other components is produced in a suitable manner, an excellent washing powder is obtained.

2. Man veräthert Al'kalicellulose mit Methyl-' Chlorid und chloräthansulfonsaurem Natrium, bis 0,3 Mol des ersteren und o,; Mol des letzteren mit der Cellulose reagiert haben. i Teil des so erhaltenen Mischäthers gibt mit i Teil dibutylnaplithalinsulfonsaurem Natrium, 2 Teilen Soda und 2 Teilen Natriummetaphosphat ein vorzügliches Waschpulver.2. Alkali cellulose is etherified with methyl chloride and sodium chloroethane sulfonic acid, up to 0.3 mol of the former and o; Moles of the latter have reacted with the cellulose. i part of the mixed ether thus obtained gives an excellent washing powder with i part sodium dibutylnaplithalinsulphonic acid, 2 parts soda and 2 parts sodium metaphosphate.
