Claim:
1. A method of fabricating fatty acids through transacylation, comprising steps of: (a) reacting an organic nitrogen-containing compound with an alkyl sultone to obtain a white solid of a zwitterionic compound; after being purified and dried, obtaining a powder of said white solid to be reacted with a Bronsted strong acid in acetic acid (HOAc) to obtain a clear viscous water-based acidic ionic liquid (IL), (b) adding a mixture of an oil (triglyceride, TG) and HOAc in said IL; using said oil and HOAc as a reactant feedstock and said IL as a catalyst to process transacylation and addition acetoxylation under reaction conditions of a temperature of 50˜150 celsius degrees (° C.) and a reaction time of 1˜72 hours (hr), (c) after reactions, recycling HOAc through vacuuming by heating under a reduced pressure; stratifying a product and said IL by staying still; taking out said product at upper layer and leaving said IL at lower layer to be recycled to repeatedly process transacylation and addition acetoxylation with said reactant feedstock added; and obtaining fatty acids, including a stabilized acetoxy fatty acid (AFFA), from said product at upper layer after taking out glycerol triacetate (GTA) through vacuum distillation.
