Reaction Steps
1712 g (5.00 mol) of bisphenol A (BPA, Bayer AG) are melted at 190° C. under a nitrogen atmosphere. 20.4 g (0.05 mol) of solid sodium bisphenolate (Na2BPA) are then added. The phenol formed is removed from the resultant melt at a bottoms temperature of 180-190° C. by distillation under a water-jet vacuum (15-20 mbar). The batch preparation is repeated five times and the crude material, from which the phenol has been removed (after separation of a total of 353 g; 3.75 mol of phenol), is combined.
