Reaction Steps
In a pressure reactor 26 g of ethylene oxide (0.59 mole) and 60 g of 2-hydroxyethyl carbamate (0.57 mole) are contacted in the presence of 1 g of potassium carbonate (0.0072 mole) at 110° C. for two hours. This resulted in an 85.3 percent conversion of 2-hydroxyethyl carbamate to products, with a selectivity to N-hydroxyethyl-2-oxazolidinone of 9.7 percent and to 2-oxazolidinone of 84.4 percent.
