Synthesis of new betaine-type amphoteric surfactants from tall oil fatty acid

Synthesis of new betaine-type amphoteric surfactants from tall oil fatty acid

Two new betaine-type amphoteric surfactants — betaineN,N'-dihydroxyethyl-N-ethyl fatty acid ester and ammoniumN-(fatty acid ester) ethyl-N,N-bis (2-hydroxyethyl)-3-(2-hydroxypropyl) sulfonate — were synthesized using tall oil fatty acids as the raw materials. Processing conditions suitable for...

Zusammenfassung:Two new betaine-type amphoteric surfactants — betaineN,N'-dihydroxyethyl-N-ethyl fatty acid ester and ammoniumN-(fatty acid ester) ethyl-N,N-bis (2-hydroxyethyl)-3-(2-hydroxypropyl) sulfonate — were synthesized using tall oil fatty acids as the raw materials. Processing conditions suitable for synthesizing the intermediates and final products were probed. In addition, the chemical structures of the intermediates and the final products were identified by infrared spectroscopy, hydrogen nuclear magnetic resonance spectroscopy, and elemental analysis.
