| titleOfInvention | Method for recovering phenol and acetone from cracking reaction product of bisphenol A residue |
| abstract | Disclosed is a method for recovering phenol and acetone from a cracking reaction product of bisphenol A residue, by which economic feasibility and efficiency can be improved by using a phenol/acetone purification process for preparing bisphenol A. The process for recovering phenol and acetone from the cracked reaction product of bisphenol a residue comprises: (a) a step of cracking cumene hydroperoxide produced by the oxidation reaction of cumene, and separating phenol and acetone; (b) a step of separating bisphenol A produced by reacting the separated phenol and acetone and cracking a purge gas stream containing the unseparated bisphenol A or a purge gas stream further concentrated by discharging and recovering part or all of the phenol in the alkaline aqueous solution; and (c) a step of separating phenol and acetone by adding a reaction product of the cracking reaction to a separation process of phenol and acetone, wherein the step (a) and the step (c) are simultaneously performed. |
