摘要: 以天然生物腰果酚为原料,经过磺化和中和两步反应合成了两种腰果酚磺酸盐表面活性剂.FT-IR光谱证实两种腰果酚磺酸盐的化学结构.采用滴体积表面张力仪和全自动旋滴界面张力仪测定了两种腰果酚磺酸盐水溶液的表面张力和油水界面张力,结果表明,两种生物质腰果酚磺酸盐具有良好的表面活性和界面活性,25℃时侧链不饱和的腰果酚磺酸盐和侧链饱和的腰果酚磺酸盐的临界胶束浓度分别为38.1mg/L和28.2mg/L,此浓度下的表面张力分别38.54mN/m和37.35mN/m;饱和腰果酚磺酸盐质量分数高于0.8%时,可将油水界面张力降低至10-3mN/m,但不饱和腰果酚磺酸盐仅能将油水界面张力降低至10-1mN/m.侧链饱和的腰果酚磺酸盐的表面活性和界面活性均优于侧链不饱和的腰果酚磺酸盐.

Abstract: Using natural cashew phenol as raw material,two cashew phenol (cardanol) sulfonates were prepared through sulfonation reaction and alkaline neutralization reaction. The products were identified by FT-IR. Their surface activity and interface activity were measured by drop volume surface tension meter and automatic spinning drop interfacial tension meter. Cardanol sulfonates had good surface activity and interface activity. the cmc values of cardanol sulfonate and saturated cardanol sulfonate in aqueous solution were 38.1mg/L and 28.2mg/L respectively,and the values of γcmc were 38.54mN/m and 37.35mN/m respectively. When the concentration was above 0.8%,interface tension of oil and water decreased to 10-3mN/m by saturated cardanol sulfonate,and interface tension of oil and water decreased to 10-1mN/m by cardanol sulfonate. Surface activity and interface activity of saturated cardanol sulfonate were superior to those of cardanol sulfonate.

Key words: cashew phenol, surfactant, surface activity, interface activity
