seeding during ultrasound-enhanced deracemization. We theorized that by introducing larger seed crystals to the system after the establishment of the monodispersed sized crystals (~2 hours)‚ we would broaden the crystal size distribution and thus allow the deracemization process to resume. To test this idea we performed seeded experiments using ultrasound‚ in which we introduced 2.5 g of large seed crystals (~200 µm‚ e_0= 40%) after sampling of the 2nd hour.
