Abstract

See full text

Fatty acids are produced through transacylation. An organic nitrogen-containing compound is reacted with alkyl sultone to generate a white solid of a zwitterionic compound. After being purified and dried, the white solid is powdered to be reacted with a Bronsted strong acid for obtaining a clear viscous water-based acidic ionic liquid (IL) as a catalyst used used to effectively process transacylation between oil and acetic acid (HOAc) for fabricating fatty acid (FFA) and glycerol triacetate (GTA). Therein, unsaturated fatty acid is simultaneously processed through addition acetoxylation to obtain stabilized acetoxy fatty acid (AFFA). After, HOAc is recycled through vacuuming. Then, the product and the IL are stratified. The product at upper layer is taken out. The IL at lower layer can be recycled for processing transacylation and addition acetoxylation repeatedly. Therein, fatty acids including the stabilized AFFA are obtained from the product after taking out GTA through vacuum distillation.
