Abstract The foaming performances of perluo-rooctanoic acid (C_7FH ),ω-chloro-oxaperfluo-rodecanoic acid(CICF),sodium a-sulfonate de-canoic acid (NaSDCH),disodium a-suldfonatedecanoate(NaSDCNa),sodium a-sulfonate de-canoic propyl ester(NaSDCP),Sodium de-canoate(DCNa)and their mixtures withalkvltrimethylammonium bromide have beeninvestigated. The aqueous solution of CICFperforms good foaming ability which is muchbetter than that of C_7FH. The mixed aqueoussolutions of C_7FH C_8N,NaSDCNa C_(10)N,NaSDCN C_(10)N,NaSDCP C_(10)N and DCNa C_(10)N show synergism in foaming performance.But CICF C_8N system is quite differentshowing weaker foaming ability,which hasbeen attributed to the particular effect of theω-chloro atom. Besides,the mixed aqueous so-lution of DCNa and C_(10) N shows low foamcharacteristics.
