【摘要】利用Pt／Al2O3催化剂，采用固定床连续工艺催化合成得到高纯度、高产率的2，3，5－三甲基氢醌，考察了反应温度、氢气分压、空速等因素对反应的影响，并通过条件试验确定了比较理想的加氢工艺条件。更多还原

【Abstract】 2,3,5-Trimethylhydroquinone with high quality and yield was synthesized by a fixed-bed continuous process with Pd/Al2O3 catalyst. The effects of reaction temperature, hydrogen partial pressure and gas velocity on the hydrogenation reaction were investigated, and the better hydrogenation conditions were found by some conditional reactions.更多还原
