• TITLE: Unsubstituted β-Alkyl Aspartates as Highly Biodegradable and Almost Nontoxic Surfactants

  AUTHORS: Sindija Brica, Maris Klavins, Andris Zicmanis

  KEYWORDS: Biodegradability, Surface Tension, Synthesis, Toxicity, Zwitterionic Surfactants

  JOURNAL NAME: Green and Sustainable Chemistry, Vol.6 No.3, August 11, 2016

  ABSTRACT: Zwitterionic surfactants—β-alkyl aspartates are prepared by the addition reaction of ammonia to alkyl maleates. Factors are discussed that influence the quality and yields of obtained β-alkyl aspartates. Structures of obtained surfactants are confirmed by 1H NMR and IR spectra. The applicability of these materials is characterized by evaluation of their surface activity, toxicity and biodegradability.
