摘要：

The influence of solvents (acetone-water mixtures) on the crystal growth kinetics of 3-methyl-4-nitropyridine-1-oxide (POM) has been investigated. Variation of the ratio of solvent components changes the solubility, with its maximum being at a water mole fraction of about 0.5, and the growth rates of individual crystal faces, and also affects the processes of defect formation. It has been shown by IR and NMR Spectroscopy that POM molecules in solution interact with those of the solvent. The surface entropy factor (alpha) for the faces of POM crystal for three different solvents has been estimated. The principal kinds of defects and their distribution in the grown crystals have been studied relative to solution compositions.
