以2,2-二(3-硝基-4-羟基苯基)六氟丙烷为主要原料,水合肼作还原剂,乙醇作做溶剂,钯碳做催化剂,合成了2,2-二(3-氨基-4-羟基苯基)六氟丙烷。通过正交实验确定了其最佳合成条件:反应温度为80℃,n(2,2-二(3-硝基-4-羟基苯基)六氟丙烷)∶n(水合肼)=0.25∶1,m(钯碳)∶m(2,2-二(3-硝基-4-羟基苯基)六氟丙烷)=0.015∶1,m(乙醇)∶m(2,2-二(3-硝基-4-羟基苯基)六氟丙烷)=4∶1,反应时间12 h,产品收率达到92.2%。 Using 2,2-bis (3-nitro-4-hydroxyphenyl) hexafluoropropane as the main raw material, hydrazine hydrate as reducing agent, ethanol as solvent and palladium carbon as catalyst, 2,2- Amino-4-hydroxyphenyl) hexafluoropropane. The optimal synthesis conditions were confirmed by orthogonal experiments: the reaction temperature was 80 ℃, n (2,2-bis (3-nitro-4-hydroxyphenyl) hexafluoropropane): hydrazine hydrate = 0.25: M (ethanol): m (2,2-bis (3-nitro-4-hydroxyphenyl) hexafluoropropane) = 0.015: - nitro-4-hydroxyphenyl) hexafluoropropane) = 4: 1, the reaction time 12 h, the product yield reached 92.2%.
