分别利用催化剂，采用固定床连续工艺，由2，3，5-三甲基苯醌合成出了高产率的2，3，5-三甲基氢醌，并与催化剂进行了性能比较。结果表明，催化剂具有较高的初选择性；同时，随着2，3，5三甲基苯醌空速的提高，初活性的下降幅度小于初活性的下降幅度。

The 2,3,5-trimethylhydroquinone with high yield was synthesized by the catalytic hydrogenation of 2,3,5-trimethylbenzoquinone with bimetallic catalysts by fixed bed continuous process. The catalytic properties of Pt catalysts were compared with those of Pd/catalysts. The results showed that Pt catalyst could increase the initial selectivity greatly. The initial activity of Pt decreased less than those of catalysts with the increase of 2,3,5-trimethylbenzoquinone space velocity.
