Abstract
In this work, the conversion of carbon dioxide into cyclic carbonates via cycloaddition involving epoxides with 1-butyl-3-methylimidazolium hydrogen sulphate as the catalyst is performed. These reactions have a potential atom economy of more than 99.9% and the ionic liquid catalysts are effective green reagents as they can be easily separated and reused after each reaction. The starting point for this work is based on previous experiments by K. Jasiak and A. Siewniak at the Silesian University of Technology in which carbon dioxide is reacted with propylene oxide in the presence of eight different ionic liquids. Important targets of this research are to study the efficiency of the production of three cyclic carbonates, propylene carbonate, 1,2-butylene carbonate, and 1,2-hexylene carbonate across a range of parameters. Reactions were run for either 12 or 24 hours at 105, 127, or 145 °C, and at a starting pressure of 15 bar. Average yields ranged from 0.0-66.0% and energy efficiency ranged from 236.0 kJ-590 kJ per 1% yield.
