D. Enjalbert et al., Preparation of new long-chain beta-amino acids and their conversion to F-alkylated double-chain carboxybetaines, J FLUORINE, 93(2), 1999, pp. 145-152
The synthesis of amphoteric F-alkylated bitailed surfactants derived from n
ew beta-aminoacid intermediates is described. N-alkyl N-benzyl amines or N-
alkyl N-methyl amines are added to acrylic acid. The beta-amino acids obtai
ned are quaternized by 2-F-alkyl ethyl acetates or thioacetate bromides to
produce the F-alkylated double-chain carboxybetaines.
