Abstract: A novel, salt-free monoamphopropionate amphoteric surfactant is prepared in yields of from 75% to 80%, from a reaction comprising an imidazoline and a mixture of acrylic acid and sodium acrylate in an aqueous medium. The acrylic acid/sodium acrylate mixture is comprised of the two components in a range of molar ratios of from about 1:6 to about 1:3, respectively, and by replacing methyl acrylate, the reaction does away with the production of methanol which is an unwanted, hazardous and toxic byproduct. The imidazoline reacts in amounts in excess of 90% resulting in the highly pure yields and any left over unreacted acrylic acid can be easily removed by treating it with sodium bisulfate.
