| 摘 要： | 采用单因素法和正交分析法研究了脂肪醇聚氧乙烯醚(3)硫酸钠(AES-3)直接转化合成脂肪醇聚氧乙烯醚磺酸钠(AESO)工艺。结果表明,优化反应条件为:w(AES-3)=14%,n(SO32-)∶n(AES-3)=4∶1,x(Na2SO3)=92%,190℃压热条件下反应4 h,磺化率为75.4%,水解率为4.6%。在上述工艺条件下磺化脂肪醇聚氧乙烯醚(2)硫酸钠、十二烷基硫酸钠和壬基酚聚氧乙烯醚(4)硫酸钠的磺化率分别为72.3%,73.5%和67.4%。

| Abstract: | Synthesis of ethoxylated fatty alcohol sulfonate(AESO) from direct conversion of ethoxylated fatty alcohol sulfate(AES-3) was studied by using single factor experiment and orthogonal experiment method.The experiment results indicated that the yield of AESO was as high as 75.4% along with only 4.6% of hydrolysis rate of AES under the optimized reaction conditions:n(SO32-)∶n(AES-3)=4∶1,x(Na2SO3)=92% and w(AES-3)=14% in aqueous solution at 190 ℃ for 4 h.Additionally,three other sulfate salts AES-2,sodium dodecyl sulfate(SDS) and sodium nonylphenyl polyoxyethylene ether sulfate(NPS-4) were prepared under the same conditions,and 72.3%,73.5% and 67.4% product yield was obtained respectively. |
