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%。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.
