| 英文摘要 | both the crystallizing molecule without long-range ordered arrangement and the complex interactions between solvent, anti-solvent, and molecule crystal challenge the imaging of molecule configurations during anti-solvent crystallization. here, the structural evolution of nh4h2po4 during anti-solvent crystallization was tracked by in situ atr-ir spectroscopy. the nh4h2po4 molecule undergoes d-2d -> c-2v -> d-2d or c-2v -> d-2d during anti-solvent crystallization, depending on both v(h2o)/v(ethanol) ratio and the concentration of nh4h2po4 aqueous solution. moreover, ir spectroscopy can also be used to confirm the anti-solvent role of ethanol in the nh4h2po4-h2o-ethanol crystallization system. the volatilization of ethanol has been demonstrated as an effective approach to control the dissolution process of nh4h2po4, which can be used to study the crystallization-dissolution-recrystallization process. the present study can shed light on the anti-solvent crystallization physical and chemistry of nh4h2po4 from a molecule-level viewpoint. |
