I. G. Farbenindustrie Akt.-Ges. in Frankfurt a. M. *) Detergents, wetting agents, dispersants and leveling agents

Patented in the German Empire from 1.6. May 1930 from

It has been found that the alkali salts primary substituted on nitrogen by higher saturated or unsaturated fatty acid residues or secondary amino monocarboxylic acids have properties that make them valuable Make textile auxiliaries. These substances can be used as Detergents, wetting agents, dispersants and leveling agents.

It is known to be amides or higher anilides To use fatty acids as auxiliaries in the production of emulsions of fatty substances : These substances are used as wetting agents and detergents because of their poor solubility Water- out of the question. In the case of the invention The substances to be used, however, are known to have their amide character completely in the Background to the influence of the carboxyl group, which leads to the formation of water-soluble Salts enabled. One had to assume from the outset that these substances were largely effective as auxiliary agents would be like ordinary soaps. Surprisingly, it has now demonstrated that the substances mentioned here McIi behave better than ordinary Be IVn in many respects. Much of the cheaper ones Properties is probably the fact that the new products or their salts are more soluble in water than ordinary soaps.

Of the amides known as wetting agents or anilides of higher sulfonated fatty acids differ from the substances of this invention due to their completely different constitution and new properties, such as B. detergency. This is where the effect comes the completely intact hydrocarbon chain of the fatty acid residue.

Condensation products are also known as wetting agents for alkaline baths low molecular weight organic sulfonic acids with aminocarboxylic acids, with nitrogen substituted sulfamides are formed. However, their effectiveness as a wetting agent only extends on alkaline baths. In contrast, the body used according to the invention on Nitrogen-substituted carboxamides, which before the mentioned wetting agents, except Their other valuable properties, preferring not only in alkaline, but to have a network effect even in neutral bathrooms.

These products are represented in a known manner, e.g. B. by condensation the Fcttsäurechloride either in aqueous alkaline solution with aliphatic aminocarboxylic acids or in pyridine solution with the

Esters of these aminocarboxylic acids with subsequent saponification of the esters of the condensation products obtainable in this way (Zeitschrift für Physiologische Chemie, Vol. 65, pp. 61 to 681. 5

example 1

A sizing liquor of 60 parts by weight is prepared Potato flour and 1 part by weight of oleyl sarcosine (Na-SaIz) in 1000 weight-ιό share water and use it to finish cotton chains. By adding oleyl sarcosine the gelatinized starch penetrates better into the thread, resulting in better tear resistance of the thread is achieved.

Example 2

■ In a solution of 10 parts by weight of oleyl

■ be sarcosine in 100 parts by weight of water 4 parts by weight of methylcyclohexanol entered with stirring. One receives on this A washing preparation that dissolves fats and oils from textiles excellently and which with the usual detergents, such as soap. Alkalis, etc., in common can be used.

Example 3

100 parts by weight of oleyl sarcosine in ι ο 000 parts by weight of a sodium hydroxide solution 23 to 26 ° Be, as used for the purposes of mercerization in the textile industry will. Oleylsarcosine dissolves easily and clearly in these alkalis and increases their wetting ability, which makes the cotton is mercerized faster and more evenly.

Example 4

In addition to the oleyl sarcosine mentioned in Example 2, mixtures of oleyl sarcosine can be used and suitable solvents such as glycol, turpentine oil, acetone, methylcyclohexanone or Monocresol glycol ether and other solvents.

; Example 5

Cotton is dyed with 3% Bauim full red 4 B (Schultz, 6th edition, 1923, no. 307, P. 102), 2 <Vo Soda, 30O / 0 Glauber's salt, i »/ o Oleylsarcosine in a boiling bath. The access

The use of oleylsarcosine results in better wetting and leveling. In a similar way you can also olcylglycine, oleyl-ct- and Use β-aminopropionic acid, etc.

Example 6

300,000 parts by weight of a Wolhvash bath are charged with 300 parts by weight of the sodium salt of oleylbutylaminoacetic acid and 12,000 parts by weight of de-welded wool were washed therein. In contrast to the ordinary Soap, this soap is much more extensive, foams particularly strong, and the washing process experiences a certain acceleration.

Example 7

100 parts by weight of a condensation product of sarcosine and a mixture liquid lower fatty acid such as are obtained from the oxidation of paraffin dissolved in a little water and ioooo parts by weight of a sodium hydroxide solution, as it is for the Purpose of mercerization in the textile industry is used, mixed.

The product mixes easily and clearly in these alkalis and increases the wettability, whereby the cotton mercerises faster and more evenly.

Example p

ro parts by weight Stearylglykokoll represented by aqueous-alkaline condensation of stearyl chloride with glycine, are stirred with 30 parts by weight of olive oil with addition of 10 parts by weight water at a temperature of 6o ^vl C and after vollkom- g ₅ mener Einulgicrung with 100 Gewichtstcilen water with stirring diluted. The result is an emulsion which can be kept well and which can be further diluted as required.

Claims (1)

Claim: Use of the water-soluble salts of nitrogen through higher fatty acid residues substituted aliphatic primary or secondary aminomonocarboxylic acids as washing, wetting, dispensing and leveling agents.
