摘要: 研究了酯基三甲氧基有机硅季铵盐(ETOQAS)的表面活性、润湿铺展性和生物降解性。结果表明:25 ℃时采用表面张力法测得ETOQAS的cmc=0.01 g/L,γcmc=15.72 mN/m;随着体系中NaCl浓度的增加,通过稳态荧光法测得的ETOQAS水溶液的cmc呈减小的趋势;随着ETOQAS水溶液质量浓度的增加,其在铁块和石蜡上的接触角逐渐减小;ETOQAS能够在3 d内降解完全。

关键词: 酯基三甲氧基有机硅季铵盐, 表面活性, 接触角, 生物降解性

Abstract: The surface properties and biodegradation characteristics of the ester trimethoxy organosilicon quaternary ammonium salt (ETOQAS) were measured.The results showed that at 25 ℃,the critical micelle concentration (cmc) of ETOQAS measured by surface tension method is 0.01 g/L,and γcmc is 15.72 mN/m.Meanwhile,NaCl was added into ETOQAS aqueous solution,and its cmc,measured by steady-state fluorescence method shows decreasing.As the mass concentration of ETOQAS increases,the contact angle on surface of iron and paraffin wax decreases.ETOQAS can be completely biodegraded within 3 d.

Key words: ester trimethoxy organosilicon quaternary ammonium salt, surface activity, contact angle, biodegradation
