主 题:ciprofloxacin hydrochloride monohydrate induction period primarynucleation diffusion growth
摘 要:A general expression for the relationship between induction periodand supersaturation was developed based on polynuclear *** mechanism of primary nucleation in solution can beillustrated by the expression. The results of induction perioddetermined by laser scattering method shows that the crystallizationof ciprofloxacin hydrochloride monohydrate in water/ethanol oraqueous solution is by the mechanism of primary nucleation followedby one-dimensional diffusion growth, and then on-dimensionalcontinuous or birth and spread growth on crystal face. The growthmechanism on the crystal face is affected by temperature and solvent.
