摘要：
The present invention relates to a catalyst for the synthesis of organic carbonates, the preparation of the catalyst and the application of this catalyst in the synthesis of organic carbonates from reacting urea and hydroxyl group containing compounds. The catalyst provided in this invention is a calcinate of hydrous salt containing rare earth element at a moderate calcining temperature.
