Synthesis method
Experiment In-house preparation method: 100 mL In a three-necked flask,Add the measured amount of phenol, Main catalyst concentrated hydrochloric acid, Heat to set temperature A certain temperature,Add measured Ding Ketones and cocatalysts, Constant temperature stirring reaction is certain Time. Pour while hot100mL Cooling in ice water,Leave overnight. Reduced pressure filtration,Wash in cold water until neutral. Vacuum drying of filter cake to remove moisture and high vacuum to remove phenol,The solid was recrystallized from toluene,Very pure bisphenol can be obtainedB.
Purpose
Chemical Engineering intermediate. Generally used in petroleum, energy and chemical industries.
