Supply and Demand in the Ball Mill: Competitive Cocrystal ReactionsAug 19, 2016 . The stability of different theophylline cocrystals under milling conditions was investigated by competitive cocrystal reactions. To determine the most stable cocrystal form under milling conditions, the active pharmaceutical ingredient theophylline was either ground with two similar coformers (benzoic acid,.ball mill for cocrystal insrtument,In Situ Investigation of a Self-Accelerated Cocrystal . - MDPIJul 14, 2016 . In a typical experiment, 1 g of the reaction mixture was ground in a ball mill (Pulverisette 23, Fritsch, Germany) in a Perspex jar for 20 min at 50 Hz. In the case of neat grinding an equimolar mixture of pyrazinamide with oxalic acid dihydrate cocrystal formation occurs very rapidly (Figure 4), (see Figure S7.
