On the basis of the differential equations of transfer 
of energy and mass, a mathematical description of the crystallization 
of solutions by decreasing continuously the pressure of the medium 
has been developed. The kinetic dependences obtained from the experiments 
have been used in simulating the process of crystallization of hexamethylene 
tetramine. By comparing the experimental and calculated data, the 
adequacy of the mathematical model to the actual process has been 
established.
