Abstract
A process for improving the recovery of solid triphenylboron-pyridine compound (TPBP), while retaining desirable particle characteristics comprises the addition of an acid to neutralize at least a portion of the alkali contained in the aqueous mother liquor. By adjusting the pH of the product slurry to between about 8.5 and about 12, it is possible to increase product recovery by more than 10%, while maintaining desirable particle characteristics.
