2,2-双(3-氨基-4-羟基苯基)六氟丙烷的制备方法

Preparation of 2,2-Bis (3-amino-4-hydroxyphenyl) hexafluoropropane

2,2-双(4-羟基苯基)六氟丙烷与硝酸钾、磷酸,反应得到2,2-双(3-硝基-4-羟基苯基)六氟丙烷,再经锌粉还原得到2,2-双(3-氨基-4-羟基苯基)六氟丙烷。该方法具有原材料易于购买,收率较高,反应条件温和,操作简单等优点。

2,2-bis(4-hydroxyphenyl) hexafluoropropane react with potassium nitrate and phosphoric acid were synthesized by reaction of 2,2-bis(3-nitro-4-hydroxyphenyl) hexafluoropropane and then reduced by zinc powder to 2,2-bis(3-amino-4-hydroxy phenyl) hexafluoropropane. The method has the advantages of easy purchase of raw materials,high yield,mild reaction conditions, simple operation.
