| 摘 要： | 求文假设在不同碱催化剂存在下的脂肪醇聚氧乙烯醚合成反应皆按等速率离子反应机理进行。从产物分布方程出发，通过适当的理论推导发现：在一定温度范围内，增加催化剂的用量，反应速度明显加快，提高催化剂的碱度也会加快反应，而产物分布随催化剂碱性及用量的增加将变宽。实验结果也证实了这些规律。

| Abstract: | In this paper. we assume that the reaction of ROH and EO was obedient to the ionic reaction mechanism of the same speed constants to the defferent catalysts. By means of the distribution formation and theroitical inference. we discover that the stronger alkalinity of catalyst and the more quantity of catalyst. the faster the reaction speed and the wider the distribution of the producti. The rule is proved by the exprimental data. |

| Keywords: | AEO catalyst The reaction speed alkalinity |
