摘　　要：以异构十醇和环氧乙烷(EO)、环氧丙烷(PO)为原料,合成了异构十醇聚氧乙烯聚氧丙烯醚。考察了原料配比、催化剂、反应温度和反应时间等因素对合成异构十醇聚醚的影响。经正交试验确定了合成异构十醇聚氧乙烯聚氧丙烯醚的最优条件为:n(异构十醇)∶n(EO)∶n(PO)=1∶5.5∶3.5,稀土络合催化剂用量为原料质量的0.6‰,反应温度为95～100℃,反应时间为5～6h。验证实验表明,制备的目标化合物相比国内一般工艺生产的产品色泽浅,分子量分散系数小,质量指标稳定性好。Isodecyl alcohol polyoxyethyelene polyoxypropylene ether was synthesized with isodacanol,ethylene oxide（EO）and propylene oxide（PO）.The effect of raw material ratio,catalyst,reaction temperature and reaction time on the synthesis of isomeric lauryl polyether was studied.Based on orthogonal experiment,the optimum conditions for the synthesis of isodecyl alcohol polyoxyethylene polyoxypropylene ether was determined and the results were as follows：n（isodecyl alcohol）∶n（EO）∶n（PO）=1∶5.5∶3.5,the amount of catalyst is 0.6‰ of the total mass.reaction temperature is 95～100℃,reaction time is 5～6 h.The experimental results showed that target product is light color,narrow distribution and stability of quality indicators,our product is better than those produced by domestic general process.
