摘　　要：实验考察了不同催化剂对1,4 二氧六环收率的影响,选用了复合钛酸作为催化剂,二甘醇法合成1,4 二氧六环,确定了合成二氧六环的理想的工艺方法和操作条件,最终产品收率达70%,纯度达99%以上.The effects of different kinds of catalysts on the yield of 1,4-dioxane were investigated. Selecting the compound tianic acid as catalyst, 1,4-dioxane was synthesized with method of diethylene glycol. The optimum process and operating conditions of synthesizing 1,4-dioxane were determined. The results show that the final yield is 70% and the purity is over 99%.
