用固定床积分反应器对合成桃金娘烯醛催化剂评价

Appraising on catalyst of α-pinene oxidation making use of firmed bed reaction

松节油用减压填料塔来精馏、收集 1 0 0～ 1 0 5℃馏分 ,得α -蒎烯 ,浓度达 95%以上。将α-蒎烯催化氧化成桃金娘烯醛 ,催化剂体系为SeO2 -V2 O5-硅藻土。采用固定床积分反应器对催化剂进行了活性、选择性和稳定性的评价。其评价结果 :选择性达 85%以上 ,催化剂使用寿命长 ,且再生性能良好 ,再生方法简便 ,催化反应条件温和且易于控制。

The reetificafion under vacuum is introduced for the separation of α-pinene from turpentine, collect α-pinene in 100～105 ℃,concentration is high 95%,appraisig catalyst SeO 2-V 2O 5 of α-pinene oxidation is conducted making use of the firmed bed reaction, The results of evaluation test: selectivity 85%; satability 75% , and the catalyst has high catalytic activity.
