制备了固体酸Hβ/SO_4~(2-)-TiO_2催化剂,以正丁醇与环氧丙烷为原料、固体酸Hβ/SO_4~(2-)-TiO_2为催化剂进行连续管式反应制备丙二醇丁醚。以环氧丙烷转化率和选择性为目标,首先考察单因素反应压力、反应温度、原料配比及空速等因素对合成丙二醇丁醚的转化率和选择性的影响,然后通过正交试验进一步优化管式反应的条件,确定最佳合成工艺条件。 The solid acid Hβ / SO_4 ~ (2 -) - TiO_2 catalyst was prepared by continuous tubular reaction of n - butanol with propylene oxide and solid acid Hβ / SO_4 ~ (2 -) - TiO_2 as catalyst . To propylene oxide conversion and selectivity as the goal, first of all, single-factor reaction pressure, reaction temperature, the ratio of raw materials and space velocity and other factors on the synthesis of propylene glycol butyl ether conversion and selectivity, and then by orthogonal test Optimization of tubular reaction conditions, to determine the best synthetic process conditions.
