Abstract
The crystallization kinetics of 2-chloro-4,6-dinitro-resorcinol were studied by the method of intermittent dynamic analysis. The nucleation rate and crystal growth rate of 2-chloro-4,6-dinitro-resorcinol under three groups of conditions (27°C, 180 rpm; 33°C, 180 rpm; 33°C, 240 rpm) were estimated. The results show that, by increasing the temperature of the solution, both the nucleation rate and crystal growth rate increase. It is further found that, when the stirring rate increases, the nucleation rate increases and the crystal growth rate decreases. On the basis of the study of the crystallization kinetics, the effect of the operational parameters on the crystallization was studied. It is proved that, when the stirring rate is 180 rpm and the solution is cooled slowly to −8°C, the particle size of the crystals is even, the quality of the crystals is good, and the yield of the crystals is 40.6%.
