The catalytic activity of an ionic liquid catalyst decreased during the transesterification of propylene carbonate (PC) with methanol to di-Me carbonate (DMC). The interaction between the strong basic sites of ionic liquid catalyst and carbonyl compounds of PC and/or DMC was considered to attribute to this deactivation. The presence of H2O accelerated this process by the formation of OH–. The strong basic ionic liquid reacted with the trace amount of H2O in the reaction system to generate OH–, which then reacted with the carbonyl structure in PC and/or DMC to form the inactive compound HCO3–, resulting in the deactivation of the ionic liquid catalyst. A plausible mechanism was proposed for the deactivation of the ionic liquid catalyst in this reaction. In the experiment, the researchers used many compounds, for example, 1,2-Propanediol (cas: 57-55-6Synthetic Route of C3H8O2).
1,2-Propanediol (cas: 57-55-6) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.Synthetic Route of C3H8O2
