【摘要】 以香兰醛为原料,通过Claisen-schmidt缩合制得脱氢姜酮,再以Pd/C或Raney-Ni催化加氢制备姜酮。比较了使用不同催化剂时姜酮的收率。更多还原

【Abstract】 From 4-hydroxy-3-methoxybenzaldehyde> dehydrogenated-zingerone was synthesied by " Claisen Schmidt" condensation, then zingerone was prepared by catalytic hydrogenation of dehydrogenated-zingerone. The catalyst was Pd/C or Raney-Ni. The productive rates of different catalysts were compared .更多还原
