| titleOfInvention | Method for producing 2,2-bis (3-amino-4-hydroxyphenyl) propane |
| abstract | PROBLEM TO BE SOLVED: To provide a high yield and high purity by a series of steps of producing a dinitro form of bisphenol A without leaving a nitrate group, and then reducing the dinitro form without leaving a metal of a catalyst. Provided is a method for producing 2,2-bis (3-amino-4-hydroxyphenyl) propane, which is the target substance. SOLUTION: First, an acetic acid solution of bisphenol A is added with 21. The required amount of concentrated nitric acid is added dropwise at a temperature of ~ 100 ° C, and then the remaining concentrated nitric acid is added dropwise at a temperature of 0 to 20 ° C to obtain a corresponding dinitro compound. Reduction using a palladium catalyst and hydrazine, and after the completion of the reduction reaction, removing all solvents including hydrazine to obtain a target product, 2,2-bis (3-amino-4-hydroxyphenyl) propane Take the process. |
