Method for preparing bisphenol A. phenol crystalline adduct, method for preparing this crystalline adduct, crystallizer therefor and method for producing bisphenol A |
| abstract |
The present invention relates to a process for purifying crystal adducts.n n n The present invention relates to a method for depositing high quality crystal adducts having a low content of microcrystalline adducts in depositing crystal adducts in a crystal column, and separately recovering high quality crystal adducts from a crystal adduct slurry.n n n The present invention also relates to a crystallizer for depositing high quality crystal adducts.n n n The present invention also relates to a process for obtaining high quality bisphenol A, which is excellent in color and free from coloration of the melt in evaporating off the phenol contained therefrom from the crystal adduct.n n n The present invention also provides a high-quality product for producing bisphenol A by a phenol evaporation step of evaporating and removing phenol contained therefrom from a phenol solution containing bisphenol A, and steam stripping the phenol-containing bisphenol A obtained from the phenol evaporation step. It is about how to get A of efficiently. |
