摘要：

Precipitation kinetics of salicylic acid from its hydrotropic solution were investigated in a laboratory-scale agitated vessel using water or dilute sulfuric acid as a precipitant. Salicylic acid concentration and pH profiles were experimentally determined. The method of s-plane analysis was used to deduce simultaneously growth and nucleation rates from transient population density curves measured by a Coulter counter. Growth and nucleation kinetic expressions in terms of significant observable variables were correlated from the experimental results. The calculated time variation of salicylic acid concentration in the solution phase and population density curves using these kinetics correlations and a simulation algorithm compare favorably with experimentally observed profiles.
