Functional poly(ionic liquid) with unique zwitterionic structure as efficient catalyst for the conversion of ethylene carbonate to dimethyl carbonate.

ABSTRACT: Dimethyl carbonate (DMC) is an important chemical raw material extensively used in organic synthesis, lithium-ion battery electrolytes, etc. The primary method for industrial synthesis of DMC involves transesterification between ethylene carbonate and MeOH but faces issues with difficult catalyst separation and low catalytic activity. Based on the synergistic catalytic activity of cation and anion, this study develops poly(ionic liquid)s of [N_XPIL][PHO] and [N₃PIL][Y] with varying alkaline sites and alkalinity levels. This is accomplished by constructing functional polymer monomers containing free radical polymerization sites and nitrogen-containing alkaline groups, and by polymerizing them with suitable cross-linking monomers in a specific ratio before exchang
