Abstract
Process for the preparation of wetting and cleaning products biocides, amphoteric, of general formula ** (See formula) ** in which A means a bivalent, aliphatic or cycloaliphatic radical that completes the nitrogen-containing ring in a 5- to 6-membered heterocycle, and in which R1 means a lipophilic hydrocarbon radical consisting of an alkyl radical of 10-16 carbon atoms, or containing one such, and R2 an alkylene radical of 1-5 carbon atoms, characterized in that a compound of the general formula is transposed ** (See formula) ** wherein R1 and A have the above meaning, with a halogen compound that introduces a carboxyalkyl radical of 2-4 carbon atoms, which compound contains the halogen atom capable of reacting in alpha, or beta position with respect to the carboxyl group , and why a conjugated carboxyl group is eventually converted to a free carboxyl group.
