中文摘要:
      以月桂醇为原料,经丙氧基化、乙氧基化、硫酸酯化和中和等系列反应合成了月桂基聚氧丙烯-聚氧乙烯醚硫酸钠(SLP3E3S)。采用FTIR、ESI-MS和1HNMR表征了其结构。测定了SLP3E3S的界面化学性质和应用性能,并与十二烷基硫酸钠(SDS)、月桂基聚氧乙烯醚硫酸钠(SLE3S)和月桂基聚氧丙烯醚硫酸钠(SLP3S)对比,考察引入聚氧乙烯链(PEO)与延展型表面活性剂中聚氧丙烯链(PPO)的协同效应。结果表明,PEO链与PPO链的协同效应使SLP3E3S在低泡性(49 mL)、对极性油的乳化力(19.4 min)和钙皂分散力(55.8 mol/mol)等方面显著优于另3种表面活性剂;而其电解质抗性(尤其是钙离子抗性)远超SDS和SLP3S,并达到与SLE3S同等水准。
英文摘要:
      Sodium lauryl polyoxypropylene-polyoxyethylene ether sulfate (SLP3E3S) was synthesized from lauryl alcohol by propoxylation, ethoxylation, sulfation and neutralization, and characterized by FTIR, ESI-MS and 1HNMR. The interfacial and application properties of SLP3E3S were tested and compared with those of sodium lauryl sulfate (SDS), sodium laureth sulfate (SLE3S) and sodium lauryl polyoxypropylene ether sulfate (SLP3S). The synergistic effects of polyoxyethylene (PEO) and polypropylene chain (PPO) of extended surfactants were investigated. The results showed that the synergistic effects of PEO and PPO led to SLP3E3S displaying the best low foamability (49 mL), emulsifying power of polar oil (19.4 min) and lime soap dispersing power (55.8 mol/mol) among four surfactants, and the electrolyte tolerance (especially the calcium ion tolerance) of SLP3E3S is as good as that of SLE3S while much better than SDS and SLP3S.
