Synthesis Method of 2,2' -bis[4-(4-aminophenoxy)phenyl]propane

2,2＇-bis[ 4-（4-nitrophenoxy）phenyl ]propane is synthesized by reaction among alkali metal carbonate or alkali metal hydroxides, 2,2- bis（4-hydroxyphenyl）propane and p-chloro nitrobenzene in a suitable solvent. Then 2,2＇-bis[4-（4-nitroophenoxy）phenyl]propane is reduced into 2, 2＇-bis [4-（4-aminophenoxy）phenyl]propane by different methods. The advantage and disadvantage of some production methods are presented from many aspects, such as the reaction conditions, yield of product, purity and whether it is suitable for large-scale production, etc. The research and development trend of 2,2＇-bis[4-（4-aminophenoxy）phenyl]propane are also pointed out.
