摘要

Emulsification of lauric acid in an aqueous eth~nol solution in- cluding lauric acid solute has been observed during cooling before crystallization of lauric acid occurs. The nature of two different so:lu- bility curves was explained for the system of lauric acid and aqueous ethanol solution. The mutual solubility of the twoliquid phases con- trols emulsification; the solid solubility of lauric acid controls crys- tallization. The mutual solubility curve appears at relatively high temperature, and the solid solubility curve at relatively low temper- ature. Crystallization essentially generates a solid metastable zone under the solid solubility curve. A supersaturated solution can be ob- tained in the metastable zone. However, no nucleation occurs in the metastable zone. The metastable zone, therefore, still caused emul- sification at low temperature before crystallization of lauric acid occurred. The hypothetical mutual solubility curve for the aqueous solution including hydrophobic solutes appeared invariably even at low temperature in the metastable zone under the solid solubility.
