An aqueous solution of diazonium salts is prepared in the absence of organic solvents by reducing a water-soluble aromatic nitro compound in aqueous solution with hydrogen and a hydrogenation catalyst to give the aromatic amino compound, and diazotizing this amino compound in the aqueous solution.

Process for the preparation of aqueous diazonium salt solutions

Compounds of the following formula are suitable as activators for peroxy compounds in laundry detergents and cleaning products:

Bleaching-active metal complexes

What is claimed is a process for preparing macropolycyclic polyamines of the formula ##STR1## where A.sup.1, A.sup.2, A.sup.3 and A.sup.4 are as defined in the description. These compounds are prepared by a novel improved process by reacting a cyclic amine of the formula ##STR2## with a compound of the formula X--A.sup.2 --Y or X--A.sup.3 --Y where A.sup.1, A.sup.2, A.sup.3 and A.sup.4 are as defined in the description and X and Y are a leaving group.

Process for preparing macropolycyclic polyamines

Use of compounds of the formula ##STR1## where the radicals R.sup.1, R.sup.2 and A are as defined in the description, as bleach activators in bleaching detergents and cleaners.

Use of aminonitrile N-oxides as bleach activators

Surfactant mixtures based on acyloxyalkanesulfonates prepared by reacting more than one mole of one or more fatty acids with one mole of a mixture of alkali metal and/or alkanline earth metal hydroxyalkanesulfonate and ammonium hydroxyalkanesulfonate in the presence of an esterification catalyst at a temperature from 100 to 260.degree. C.

Surfactant mixtures comprising acyloxyalkanesulfonates

The invention relates to the use of compounds of the formula ##STR1## as bleach activators in detergents and cleaners, where R.sup.1, R.sup.2, R.sup.3 and R.sup.4, X and A are as defined in the description.

Use of formamidinium salts as bleach activators

Surfactant mixtures containing acyloxyalkanesulfonates, which are prepared by mixing different acyloxyalkanesulfonates, the total quantity of acyloxyalkanesulfonates comprising a mixture of ammonium and alkali metal and/or alkaline-earth metal cations.
