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.
