中文摘要: |
基于氢转移原理,以醇为氢源,将RANEY©Ni催化剂用于三乙酸内脂(TAL)的加氢反应.通过筛选醇溶剂等条件,在氮气气氛中,以异丙醇为氢源,50℃下反应10 h可高选择性地制得89%的4-羟基-6-甲基四氢-2-吡喃酮.循环稳定性实验和氨基酸毒化实验证实RANEY©Ni催化剂在该反应中优异的稳定性. |
英文摘要: |
A catalytic transfer hydrogenation process was developed for the production of 4-hydroxy-6-methyltetrahydro-2-pyrone from biologically derived platform molecule triacetic acid lactone (TAL) under mild conditions. With isopropyl alcohol as hydrogen donor, RANEY©Ni showed high activity with selectivity of 89% within 10 h. After 17 rounds of recycle experiments, RANEY©Ni still exhibited good catalytic activity and it also showed high stability during TAL hydrogenation to 4-hydroxy-6-methyltetrahydro-2-pyrone in the presence of amino acid. |
