Water-Doped Br ønsted Acidic Protic Ionic Liquids for Enhanced Tributyl Citrate Synthesis in a Two-Phase Esterification System

Chem Asian J. 2024 Mar 3:e202400006. doi: 10.1002/asia.202400006. Online ahead of print.ABSTRACTTributyl citrate (TBC) plays a crucial role as a plasticizer, enhancing the flexibility of polymers like polyvinyl chloride. Its biodegradability and non-toxic nature contribute to its eco-friendly appeal, making it a preferred additive in diverse industries, including food packaging, medical devices, toys, and consumer goods. Herein, a method for the synthesis of TBC using inexpensive Brønsted acidic protic ionic liquids (ILs) in a two-phase reaction system is presented. The esterification process is carried out with high yield (>99%), selectivity (up to 98%) and short reaction time of 2h. The catalyst in the form of IL shows excellent performance and stability, desirable for industrial applications.PMID:38433098 | DOI:10.1002/asia.202400006
