Using the spectrophotometric method, as a new method, the influence of dextran on the sucrose solubility and metastable zone width has been studied. In agreement with the literature the experimental data show that the dextran has a negligible effect on the sucrose solubility. The results also show that this impurity decreases the sucrose metastable zone width. The study of the nucleation kinetics performed, using Nyvlt’s approach, shows that the dextran accelerates the nucleation and that the nuclei are formed in the solution by instantaneous nucleation. The presence of dextran in the system causes a decrease in the growth rate of sucrose. The growth process of sucrose is governed by a Birth and Spread mechanism. The kinetic parameters of sucrose growth in aqueous solutions without and with dextran were estimated.

Solubility of pentaerythritol in water has been determined using literature data, the polythermal method and the dry residue method. Densities of its aqueous solutions have been measured using a pycnometer. Kinetics of crystallization of the pentaerythritol has been determined in laboratory experiments. In this paper, metastable zone width measurements have been employed for the assessment of the primary nucleation rate.
