摘要
对全氟辛酸、ω－氯代氧杂全氟癸酸、癸酸钠及三种ａ－磺基癸酸盐与烷基三甲铵盐混合水溶液起泡性质进行了研究。结果表明，ω－氯代氧杂全氟癸酸有很低的临界胶团浓度，仟低水表面张力的能力很强，并有很好的起泡性能。它与溴化辛基三甲铵混合体系的起泡性却与一般正负表面活性剂混合体系迥异，混合体系的起泡性反劣于单一体系。这破归之于ω－氯代结构的特殊影响。全氟辛酸和三种ａ－磺基癸酸衍生物与烷基三甲铵盐混合水溶肤泡沫性质比单一溶液均显著增强，而癸酸钠与烷基三甲铵盐混合水溶液起泡性却明显削弱。
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.
