Syntheses and Surface Active Properties of Amphoteric Surfactant(4) - Syntheses of Sulfonated or Sulfated Derivatives from Imidazoline -

1-(2-hydroxyethyl)-2-undecyl-2-imidazoline[Ⅰ] was converted into various types of sulfonated or sulfated amphoteric surfactants as following. ㆍ1-(2-hydroxyethyl)-1-(3-sulfonatedpropyl)-2-undecyl-2-imidazolium[Ⅲ] ㆍ1-(2-sulfatedethyl)-1-methyl-2-undecyl-2-imidazolium[Ⅳ] ㆍ1-dioxylethylene methyl sulfonated-l-methyl-2-undecyl-2-imidazolium[Ⅴ] ㆍN-[N -(2-hydroxyethyl-N -(3-sulfonatedpropylammonio]ethyl dodecanoylamide[Ⅵ] ㆍMono sodium N-[N -(2-hydroxyethyl)-N -disulfonatedpropylammonio]ethyl dodecanoyl amide [Ⅶ] ㆍN-[N -(2-hydroxyethyl-N -(2-hydroxypropl-N (3-sulfonatedpropyl)ammonio] ethyl dodecanoyl amide[Ⅷ] The alkylimidazolines could be readily hydrolyzed to give amidoamines, but by quaternerization, hydrolysis stability of imidazoline and amide type amphoteric surfactantes were increased in the alkali and acid conditions. Also, at least three carbon chains introduce to the main group, water solubility was sparingly increased.
