摘　　要：以过量的乙二醇与三氧化二锑进行脱水反应 ,用苯为带水剂将生成的水带出 ,反应产物通过定性分析证明为乙二醇锑。采用正交实验设计方法确定较佳的合成条件为 :三氧化二锑与乙二醇的摩尔比为 1∶ 5 0 ,温度为 1 80℃ ,反应时间为 1 5 0 min。The synthetic method of antinomy glycolate from Sb 2O 3 and excess HOC 2H 4OH with benzene as water carrying agent was studied by orthogonal experiment design. The optimum conditions were found that the mole ratio of Sb 2O 3∶HOC 2H 4OH=1∶50, reaction temperature 180 ℃ and reaction time 150 min. The advantages of this method were discussed.
