合成维生素E工业过程中炔醇选择性加氢催化剂的研究进展

Research Progress on Catalysts for the Selective Hydrogenation of Propargylic Alcohols in the Industrial Processes for the Synthesis of Vitamin E

综述了用于合成维生素E工业过程中重要炔醇,包括去氢芳樟醇、去氢橙花叔醇和去氢异植物醇,选择性加氢催化剂的研究进展。此外,毒化剂,例醋酸铅、喹啉、吡啶等,对选择性加氢催化剂的活性和选择性的影响进行了概述。最后,对这类选择性加氢催化剂的改进提出了展望。

The catalysts used for the selective hydrogenation of propargylic alcohols,including dehydrolinalool,dehydronerolidol,and dehydroisophytol,as important intermediates for the synthesis of vitamin E are overviewed.Additionally,the effects of different poisons,such as lead acetate,quinoline,and pyridine et al.,on the catalytic activity and selectivity of selective hydrogenation catalysts are addressed.Finally,the improvement of this type of selective hydrogenation catalysts is anticipated.
