Recovering method of phenol and acetone from cracking reaction product of bisphenol-a residue |
| abstract |
Disclosed is a process for recovering phenol and acetone from a bisphenol-A decomposition reaction product, which can improve economic efficiency and efficiency by utilizing a phenol / acetone purification process used in the production of bisphenol-A. The method for recovering phenol and acetone from the decomposition product of bisphenol-A residue comprises: (a) decomposing and purifying cumene hydroperoxide produced by the oxidation reaction of cumene to separate phenol and acetone; (b) isolating the bisphenol-A produced by reacting the separated phenol and acetone, and purifying the purge stream or the phenol containing the bisphenol- Decomposing the stream under an alkaline aqueous solution; And (C) feeding the reaction product obtained by the decomposition reaction to a step of separating the phenol and acetone to separate phenol and acetone, wherein the steps (a) and (c) are performed simultaneously . |
