合成2,3,5-三甲酚催化剂的研究

Synthesis of 2,3,5-Trimethylphenol over an Iron Catalyst

采用等体积浸渍法制备负载型催化剂用于3,5-二甲酚甲基化反应,在固定床反应器中考察了载体的焙烧温度、助剂、催化剂的焙烧温度和焙烧时间等因素对催化剂活性影响分析。结果表明:Fe2O3-Cr2O3/Al2O3催化剂在反应中具有较高的反应活性和选择性。

Gas-phase alkylation of 3,5-xylenol by methanol over a catalyst containing iron oxide as the main component in a fixed-bed continuous process was studied. The effects of the support grill temperature, Cr content, the calcination temperature and time of catalysts were investigated. By means of some experiments, it was found that the catalysts had good activity and selectivity in the reactivity.
