RECOVERY OF PHENOL AND ACETONE FROM BISPHENOL-A STREAMS
IN A METHOD OF RECOVERING PHENOL AND ACETONE FROM A FEED STREAM CONTAINING BISPHENOL-A AND ISOMERS THEREOF, THE FEED STREAM IS CONTACTED WITH WATER AND A SOURCE OF HYDROXYL IONS UNDER CONDITIONS EFFECTIVE TO DECOMPOSE AT LEAST PART OF SAID BISPHENOL-A AND ISOMERS THEREOF TO PHENOL AND ACETONE. THE C...

| description | IN A METHOD OF RECOVERING PHENOL AND ACETONE FROM A FEED STREAM CONTAINING BISPHENOL-A AND ISOMERS THEREOF, THE FEED STREAM IS CONTACTED WITH WATER AND A SOURCE OF HYDROXYL IONS UNDER CONDITIONS EFFECTIVE TO DECOMPOSE AT LEAST PART OF SAID BISPHENOL-A AND ISOMERS THEREOF TO PHENOL AND ACETONE. THE CONDITIONS INCLUDE A TEMPERATURE OF ABOUT 150 °C TO 300 °C, A PRESSURE SUFFICIENT TO KEEP THE WATER SUBSTANTIALLY IN THE LIQUID PHASE AT SAID TEMPERATURE, AND A MOLAR RATIO OF HYDROXYL IONS TO HYDROXYPHENYL GROUPS IN THE RESIDUE STREAM FROM 0.3:1 TO 0.9:1.
