METHOD OF LEATHER AND FUR TREATMENT

A process for the preparation of compounds of the formula I in which R1 denotes a saturated or unsaturated alkyl radical or alkoxyalkyl radical having 1 - 22 carbon atoms, preferably 12 - 18 carbon atoms, R2 denotes an alkyl radical having 1 - 18 carbon atoms, a saturated or unsaturated carboxyalkyl...

Summary:A process for the preparation of compounds of the formula I in which R1 denotes a saturated or unsaturated alkyl radical or alkoxyalkyl radical having 1 - 22 carbon atoms, preferably 12 - 18 carbon atoms, R2 denotes an alkyl radical having 1 - 18 carbon atoms, a saturated or unsaturated carboxyalkyl radical having 3 - 4 carbon atoms, a carboxyphenyl radical or a carboxyl radical (-COOH), R3 denotes hydrogen or CH3 and X denotes hydrogen, alkali metal, alkaline earth metal, ammonium, alkylammonium or alkanolammonium and A represents C=O, SO2, or an alkylene radical having 0-3 C atoms, which is characterised in that alkylamines of the formula R1-NH2, in which R1 has the meaning described above, are added to (meth)acrylic acid and the resulting N-alkylaminopropionic acids are reacted with carboxylic anhydrides, carbonyl chlorides, sulphonyl chlorides, isocyanates, halocarboxylic acids or (meth)acrylic acids and are then optionally at least partially neutralised. Novel N-alkyl-N-(2-carboxyethyl)sulphonamides and N-alkyl-N-(2-carboxyethyl)ureas are additionally described.
