Stability of aspirin in solid mixtures.
It has been shown that the degradation of aspirin in mixtures may be monitored by thermal analytical techniques. The methodology employed differential scanning calorimetry and thermal gravimetric analysis by standard techniques providing simple and rapid analysis for screening the stability of aspirin in mixtures. The degradation was found to depend on the nature of the additive but, in particular, the presence of acidic or basic groups within its structure.
