Preparation and surface active properties of alkali salts of N-perfluorooctanoylamino acids

Preparation and surface active properties of alkali salts of N-perfluorooctanoylamino acids. Kimura, Chikai; Kashiwaya, Kageaki; Kobayashi, Mitsunobu; Murai, Koichi; Nishiyama, Tatsuo (Min. Coll., Akita Univ., Akita, Japan). Yukagaku, 33(12), 838-42 (English) 1984.Several reagents such as 3108-24-5 is used here. CODEN: YKGKAM. ISSN: 0513-398X. DOCUMENT TYPE: Journal CA Section: 46 (Surface Active Agents and Detergents) Section cross-reference(s): 23 Et perfluorooctanoate [3108-24-5] was heated 2 h at 30° in EtOH with the Et ester of glycine [56-40-6], D,L-a-alanine [302-72-7], or b-alanine [107-95-9] to prep. the N-perfluorooctanoyl derivs. of amino acid esters which were sapond. to give the Na, K, and Li salts. The surfactant properties of these nine salts were detd. The glycine derivs. had low soly. in water and poor surface activity. The a- and b-alanine derivs., esp. the latter, had good surface activity, giving surface tensions as low as 15 dynes/cm. .

Preparation and surface-active properties of sulfopropylated N-alkylperfluorooctanamides

Preparation and surface-active properties of sulfopropylated N-alkylperfluorooctanamides. Kimura, Chikai; Kashiwaya, Kageaki; Kobayashi, Mitsunobu; Nishiyama, Tatsuo (Min. Coll., Akita Univ., Akita 010, Japan). JAOCS, J. Am. Oil Chem.Several substances with their cas registry numbers 89685-57-4 and 89685-56-3 may be metioned in this study. Soc., 61(1), 105-7 (English) 1984. CODEN: JJASDH. DOCUMENT TYPE: Journal CA Section: 46 (Surface Active Agents and Detergents) Section cross-reference(s): 23 Nine amides C7F15CONHR (R = H, Me, Et, C3H7, C4H9, C6H13, C8H17, C10H21, C12H25) were prepd. by the reaction of Et perfluorooctanoate [3108-24-5] with NH3 or an alkylamine and then converted to the amides C7F15CONR(CH2)3SO3Na by treatment with propanesultone [1120-71-4]. The sulfonate having R = C4H9 generally had the best surfactant properties. .
