Reaction Steps
In a reactor 30 g of 2-hydroxyethyl carbamate (0.29 mole) are contacted with 25 g of ethylene carbonate (0.29 mole) in the presence of 0.6 g of potassium carbonate (0.0043 mole) at 150° C. for five hours. The reaction results in a conversion of 91 percent of the 2-hydroxyethyl carbamate with a selectivity to 2-oxazolidinone of 53 percent and N-(2-hydroxyethyl)-2-oxazolidinone of 18 percent.
