摘要
以脂肪醇、二苯醚和发烟硫酸为原料,经烷基化、磺化、中和反应合成了一系列烷基二苯醚双磺酸钠(C12ADPOS、C14ADPOS和C16ADPOS),并采用高效液相色谱(HPLC)对磺化产物进行了分析.测定了ADPOS的表面张力、乳化和泡沫性能.C12ADPOS、C14ADPOS和C16ADPOS的临界胶束浓度分别为2.16×10-4、5.98×10-5和6.84×10-5mol/L,临界胶束浓度时的表面张力分别为37.3、36.3和34.8 m N/m,泡沫和乳化能力随ADPOS碳链的增长先增大后减小.
Alkyl diphenyl oxide disulfonates (C12ADPOS, C14ADPOS and C16ADPOS) were synthesized us-ing fatty alcohols, diphenyl oxide and oleum as raw materials through alkylation-sulfonation-neutralization. The sulfonation product was analyzed using HPLC. Surface tension, emulsification and foam performance of AD-POS were determined. Critical micel e concentration (cmc) of C12ADPOS, C14ADPOS and C16ADPOS was 2.16 × 10^-4, 5.98 × 10^-5 and 6.84 × 10^-5 mol/L, respectively. Surface tension of C12ADPOS, C14ADPOS and C16ADPOS at cmc was 37.3, 36.3 and 34.8 mN/m, respectively. Foam and emulsification performance of ADPOS increased first, and then decreased with increasing the carbon chain.
