Abstract
Abstract Triamine-trioxides of the formula ##STR1## in which R denotes a saturated or an olefinically unsaturated hydrocarbon radical which has 1 to 3 double bonds and 8 to 22 carbon atoms, n 1 and n 2 represent an integer from 2 to 3, and n 1 and n 2 can be identical or different, and a, b, c and d, which are identical or different, each is a number from 1 to 5, with the proviso that the sum (a+b+c+d) should be at most 10. The compounds are prepared from primary amines of the formula RNH 2 by dicyanoalkylation, hydrogenation, ethoxylation and oxidation with hydrogen peroxide. They are suitable for formulating industrial and also cosmetic cleaning agents.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
85 words
A triamine-trioxide of the formula ##STR7## in which R denotes a saturated or an olefinically unsaturated hydrocarbon radical which has 1 to 3 double bonds and 8 to 22 carbon atoms, n 1 and n 2 represent an integer from 2 to 3, and n 1 and n 2 can be identical or different, and a, b, c and d, which are identical or different, each is a number from 1 to 5, with the proviso that the sum (a+b+c+d) should be at most 10.
Claim 2
Dependent Claim
85 words
A triamine-trioxide of the formula ##STR7## in which R denotes a saturated or an olefinically unsaturated hydrocarbon radical which has 1 to 3 double bonds and 8 to 22 carbon atoms, n 1 and n 2 represent an integer from 2 to 3, and n 1 and n 2 can be identical or different, and a, b, c and d, which are identical or different, each is a number from 1 to 5, with the proviso that the sum (a+b+c+d) should be at most 10.
Claim 3
Dependent Claim
95 words
A process for preparing a triamine-trioxide as claimed in claim 1, in which, first, a primary amine of the formula RNH 2 (II) is reacted with 2 moles of at least one reactive nitrile of 2 to 3 carbon atoms to give a compound of the formula ##STR8## which is reduced in the presence of hydrogen to give a compound of the formula ##STR9## which is condensed with ethylene oxide to give a compound of the formula ##STR10## which process comprises oxidizing this compound of the formula (V) in an aqueous solution with hydrogen peroxide.
Claim 4
Dependent Claim
46 words
An industrial cleaning agent, containing water as a liquid carrier, at least one surfactant from the group consisting of anionic, cationic, nonionic and amphoteric surfactants and, cleaning-promoting additives and customary auxiliaries, which comprises a surface active effective amount of a triamine-trioxide as claimed in claim 1.
Claim 5
Dependent Claim
45 words
A cosmetic cleaning agent, containing water as a liquid carrier, at least one surfactant from the group consisting of anionic, cationic, nonionic and amphoteric surfactants, customary cosmetic additives and auxiliaries, which comprises a surface active effective amount of a triamine-trioxide as claimed in claim 1.
