The invention provides a process for the preparation of dialkyl carbonates of general formula (1) wherein R=alkyl (C1-C8) or C6H5CH2. The said process comprises a reaction between cyclic carbonate and alcohol, in the presence of a solid, double metal cyanide complex catalyst, at a temperature in the range of 140-180 0C., for a period of 4-10 hrs, followed by the separation of catalyst from the above said reaction mixture by known methods to obtain the desired product.
