Abstract: Synthesizing bio-plasticizers with acidic ionic liquids as catalysts. The acidic ionic liquids are Bronsted acidic ionic liquids, which are composed of alkyl sulfone pyridinium and strong Bronsted acid. Epoxidized fatty acid alkyl esters could be obtained via epoxidation of fatty acid alkyl esters using the acidic ionic liquids as catalysts. The epoxidized fatty acid alkyl esters perform well as bio-plasticizers, which could be substituted for phthalate ester plasticizers. The acidic ionic liquids catalysts provide good catalytic performance, are easy to separate, reusable, and may reduce corrosion of pipelines.

Abstract: 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.

Abstract: The present invention uses a nitrogen-containing organic compound to be reacted with an alkyl sultone to obtain a zwitterion compound. The zwitterion compound is reacted with a heteropoly acid (HPA) to obtain an ionic liquid HPA (IL-HPA). The IL-HPA is used for acetylation of polyol and HOAc for obtaining polyol acetate. The IL used in the reaction can be recycled. Thus, problems of product separation, waste acid handling, and corrosion of facilities are solved and production through esterification is improved with a green catalysis.
