Abstract:
1. A process for producing bis-N-alkyl polyether, bis-N-alkenyl polyether, bis-N-cycloalkyl polyether, bis-N-aryl polyether bis-beta or alpha-amino acids or their salts having the formula XII where: R R R R R R n and m can have values from 1 to 250, and i can have values of 0 and 1: In the radical —COOX used in R —H, an alkyl, alkenyl group, a cycloalkyl or aryl group, or a metal; wherein said process comprises the reaction scheme wherein the secondary amine of Formula VIII is reacted with a compound of Formula IX to obtain the compound of Formula IX to obtain the compound of Formula X, wherein said compound of Formula IX is selected from the group consisting of unsaturated alpha or beta acids and salts thereof, halogenated acids and salts thereof, and unsaturated esters, and reacting the resulting compound of Formula X with a compound of Formula XI, where X is selected from the group consisting of bromide, chloride and iodide, and R
