Beschreibung
Zusammenfassung:	The invention relates to a new method for preparation of plant oil fatty acid ethyl ester, wherein the method comprises the following steps: (1) taking plant oil, and preheating the plant oil to 65-75 DEG C; (2) taking KOH, putting the KOH into absolute ethyl alcohol, and making the KOH completely dissolved in the absolute ethyl alcohol by ultrasonic treatment, to obtain a KOH ethyl alcohol solution; (3) mixing the preheated plant oil with the KOH ethyl alcohol solution, then connecting to a hydrodynamic cavitation device, and carrying out a circular reaction for 10-30 min under a condition of the temperature of 65-75 DEG C; and (4) after the end of the reaction, adjusting the pH value of the product to neutral, and carrying out rotary evaporation for 25-35 min under a condition of the temperature of 65-75 DEG C, to obtain the plant oil fatty acid ethyl ester. With the plant oil as the main raw material, and with use of the hydrodynamic cavitation technology, the fatty acid ethyl ester is prepared, the prepar
