| Abstract: | Using a laser monitoring observation technique, the solubilities and crystallization metastable zone of DL-p-hydroxyphenylglycine in water-acetone solvent are determined. It is found that, the solubilities increase slightly with the increase of water in solvent,but increasing the acid concentration results in significant increase of solubilities.Acid concentration also affect the metasable zone significantly.By means of solubility model to correlate the experimental results, the calculated solubilities show good agreement with experimental values. |
