[Pressure-course events in the tabletting of phenylbutazone]

The distribution to different compression phases via formation of the 1. derivation of the increased force curve is elucidated by the example of the phenylbutazone (2. AB-DDR) compression by means of an instrumented, slow-motion (1 r. p. m.) excentric press, equipped with piezoelectric force recorders and semiconductor transducers articulated to the upper stamp. In the case of phenylbutazone it is subdivided into at least three sections.
