Abstract

Four anionic surfactants having two polyfluoroalkyl chains in a molecule, sodium salt of bis (1H, 1H, 2H, 2H-heptadecafluorodecyl) 2-sulfosuccinate, CF 3 (CF 2) 7 (CH 2) 2 OCOCH 2 CH (SO 3 Na) COO (CH 2) 2 (CF 2) 7 CF 3, sodium salt of bis (1H, 1H, 9H- hexadecafruorononyl) 2-sulfosuccinate, H (CF 2) 8 CH 2 OCOCH 2 CH (SO 3 Na) COOCH 2 (CF 2) 8 H, sodium salt of bis (1H, 1H, 7H-dodecafluoroheptyl) 2-sulfosuccinate, H (CF 2) ...
