Abstract
The kinetics of detachment of the acid anions and their transfer into solution is investigated for the preparations of succinic acid obtained mechanochemically. It is established that under the experimental conditions this process goes on almost completely within 1 min for the composites based on talc and for the known pharmaceutical preparations «Yantar-antitox» and «Yantarnaya kislota» (succinic acid). Dissolution of the composites based on kaolinite occurs gradually during 20 min and depends on activation time. The reasons of differences in the solubility of preparations are discussed.
