【摘要】 在乙醇介质中 ,以Fe(OH) 3 /C为催化剂 ,用 80 %水合肼将 2 ,2 二 ( 4 羟基 3 硝基 )苯基丙烷还原为 2 ,2 二 ( 4 羟基 3 氨基 )苯基丙烷。产率 99.0 % ,纯度 98.5 %。考察了 1 0种金属离子对催化剂活性的影响 ,结果发现Pb2 + 会引起催化剂中毒 ;Mg2 + ,Cu2 + 和Zn2 + 钝化了催化剂的催化活性 ;Ba2 + 和Cr3 + 不影响催化剂的活性 ;Al3 + ,Ni2 + ,Ti3 + 和Ti4+ 能活化催化剂 ,使反应速度加快 ,但它们单独使用时无催化活性。更多还原

【Abstract】 Bis(4-hydroxy-3-amido-phenyl)-propane was reduced from 2,2-bis(4-hydroxy-3-nitro-phenyl)-propane using Fe(OH) 3/C as a catalyst in the alcohol solvent with hydrazine hydrate. The yield was 99% and the purity was 98.5%. The influence of some metal ions on the catalytic activity of Fe(OH) 3/C was investigated. The results shown that Pb 2 + brought about the catalyst poisoning, Mg 2 + , Cu 2 + and Zn 2 + blunt the catalytic activity, Ba 2 + and Cr 3 + had hardly affect the catalytic activity, Ni 2 + , Al 3 + , Ti 3 + and Ti 4 + can activate the catalyst, but they had no activity to the reaction as a catalyst alone.更多还原
