Webb18 juli 2024 · The Prout–Tompkins autocatalytic model satisfactorily described the reactions, resulting in activation energy values E a within 45−54 kJ/mol. However, for the CO/PE blend, the difference between the reactivity of the polyols and the solubility parameter with pMDI results in a two-step reaction kinetics. WebbThe anhydrous acidic form of ampicillin is very stable in solid phase. Therefore, it can be recomended to be formulated in peroral ampicillin pharmaceutical preparations. Ampicillin trihydrate, now used in pharmaceutical formulations, is less stable than the last mentioned compound. It degrades according to Prout-Tompkins' model.
