The compatibility and non- isothermal crystallization of fractionated palm oil greatly affect the quality offractionated palm oil- based plastic oils.For better application of fractionated palm oil,the compatibility of theblends of palm stearin (44℃) and palmitin (24℃) was studied by means of pulsed nuclear magnetic resonanceand isothermal crystallization curves,and the non- isothermal crystallization behavior of the blends was investigatedvia differential scanning calorimetry.The results show that the binary system of palm stearin and palmitin is of goodcompatibility and forms a eutectic mixture only when the palm stearin proportion and the temperature are respective-ly higher than 50% and 33.3℃. Moreover,it is found that,during the non- isothermal crystallization of theblends,the exothermic peak broadens and the peak temperature increases with the palm stearin proportion at a con-stant cooling rate,and that the enthalpy variation increases with the cooling rate when the palm stearin proportionkeeps constant.
