DIBUTYL CARBONATE Usage And Synthesis
Chemical Propertiesliquid
UsesDibutyl Carbonate is a potential fuel substitute due to the observed decrease in CO2 emissions. Also used in CO2 catalytic activation.
PreparationA 160 mL Parr autoclave was charged with butanol 982 (2.22 g, 0.03 mol), N-cyclohexyl-N',N',N'',N''-tetramethylguanidine (CyTMG; 6.9 g, 0.035 mol), and acetonitrile (30 mL). The autoclave was attached to a pressure head, and 160 psig CO2 was introduced with stirring at room temperature. An exothermic reaction ensued, leading to an increase in temperature to ca. 40℃. In a Fischer–Porter bottle was placed a solution of 1-chlorobutane (8.33 g, 0.09 mol) in acetonitrile (10 mL). This bottle was attached to a pressure head, and 80 psig CO2 was introduced above the solution. After 1 h, the solution of 1-chlorobutane was added in one portion under 80 psig CO2 to the pre-formed carbonate anion solution generated in the autoclave. After the addition, the pressure was increased to 160 psig with CO2, and the reaction mixture was warmed to 85 ℃ for 16 h. Thereafter, the reaction mixture was allowed to cool to room temperature, and then the pressure was released. An aliquot was removed, diluted with diethyl ether, and CyTMGH+Cl- was filtered off; by GC analysis using biphenyl as an internal standard, the yield of dibutyl carbonate was calculated as 73%; oil.
