The kinetics of growth and dissolution of adenine sulphate in 1.5 mol · 1 −1 H 2 SO 4 at different super‐ and undersaturations has been studied. The solubility of adenine sulphate in H 2 SO 4 was determined over the temperature range 20–50 °C. The growth rate of the (100) face is by about 25% higher than that of (111) and the crystal habit is changed by a high supersaturation almost to a bipyramide. The surface diffusion was determined as a prevailing processes and the BaS model gives the best fit with experimental data.
