The nucleation and crystal growth of sodium chloride in aqueous solution during crystallization by ethanol droplet feeding were investigated by determining the suspension density and crystal size distribution. Crystallization was conducted in a microwave reactor, and the effect of the power, stirring speed, and ethanol concentration were investigated to clarify the anti-solvent effect under microwave radiation. Molecular diffusion was accelerated by fine particle production due to microwave radiation when the stirring speed was low and ethanol concentration was high. However, moderate microwave power and stirring speed were required for efficient molecular diffusion.

通过测定悬浮密度和结晶尺寸分布，研究了乙醇滴入结晶过程中氯化钠在水溶液中的成核和晶体生长。在微波反应器中进行结晶，考察了功率、搅拌速度和乙醇浓度对微波辐射下的抗溶剂效应的影响。当搅拌速度低、乙醇浓度高时，微波辐射产生的细颗粒加速了分子扩散。然而，适当的微波功率和搅拌速度需要有效的分子扩散。
