摘要 |
The present invention relates to a method for preparing dialkyl carbonate, which enables the preparation of a dialkyl carbonate, such as dimethyl carbonate, at a higher yield rate in an eco-friendly and economically advantageous manner while reducing the generation of by-products. The method for preparing dialkyl carbonate comprises a step of reacting urea, alkyl carbamate having 1 to 3 carbon atoms or a mixture thereof, and a monovalent alcohol having 1 to 3 carbon atoms in the presence of a room-temperature ionic liquid and a catalyst comprising salts of transition metals or rare-earth metals. |
