摘　　要：在（Ⅰ）报与（Ⅱ）报的基础上，考虑脂肪酸乳液结晶过程的特殊性，提出了以降温速率Ｔ表示结晶过程推动力的非等温结晶过程动力学方程式：ｍ＝ｋＴｎ。实验求取了不同分离温度下不同饱和酸（ＳＦＡ）含量的体系之ｋ及ｎ值，大多数物系ｎ＝０．９２±０．０５，ｋ＝０．８０～１．３０。n the basis of the previous papers. authors considered the speciality of the crystal process of fatty acids from emulsion, and took the decreasing rate of temperature as the driving force of the crystal process, and then presented the kinetic equation of the non-thermal process of crystallization: m=kTn. By experiments authcrs got the values of k and n of systems which are separated at several temperatures, and found out that n is equal to 0.92±0.05 and k is equal to 0.80￣l.30 in most cases.
