摘要：NOVELTY - A process for continuously preparing diethyl carbonate features that the diethyl carbonate is prepared from dimethyl carbonate and alcohol through reaction and rectification in the presence of catalyst. After the alcohol, diethyl carbonate and catalyst are separated from each other, the alcohol and catalyst can be cyclically used and the concentration of diethyl carbonate can reach 99.5 wt. %. After the methanol and alcohol at tower top are separated, the alcohol can be cyclically used.
