摘要
研究了磷钨酸、活性炭负载磷钨酸催化α 蒎烯的异构化反应 ,考察了反应条件对α 蒎烯转化率和产物选择性的影响。结果表明 :活性炭负载磷钨酸催化α 蒎烯的异构化反应具有反应温度低、催化活性高、莰烯和烯选择性高等优点 ,将磷钨酸负载于活性炭载体上以后 ,其催化活性和稳定性增大 ,并可重复使用。
Isomerization of α pinene was studied over phosphotungstic acid and activated carbon supported phosphotungstic acid catalysts.Influences of the reaction condition on conversion and selectivity of products were investigated.The experimental results show that solvents and temperature have obvious influence on activity of the catalyst and that HPW catalyst has both high catalytic activity and selectivity even at lower temperature to produce the expected camphene and limonene isomers.After being supported on activated carbon, the catalytic activity and stability of phosphotungstic acid have been improved greatlty and the catalyst can be reused.
