Abstract:
Object To study the technological conditions of refining ?-linolenic acid by short-path distillation (SPD). Methods According to the characteristic of SPD, the effect of the operating parameters, such as the distillation temperature, the system pressure, the feeding rate, and the agitating speed, were studied on the purity of ?-linolenic acid. Results The appropriate process conditions for the purification of ?-linolenic acid by SPD are: distillation temperature 90 ℃—120 ℃, pressure 0.3 Pa, feeding temperature 60 ℃, feeding rate 90—100 mL/h, and rotating speed 150 r/min. Conclusion Refining ?-linolenic acid by SPD is a simple and convenient method. It is easy to achieve industrialization.
