The present application relates to a process for the preparation, the polycarbonate manufacturing apparatus of the polymer solution and the polycarbonate of the polycarbonate. An exemplary method for manufacturing polycarbonate of the present application, there can be provided a polycarbonate polymer liquid purified by using a dichloromethane solvent for re-use to a distillation tower includes a very small amount tetrachloromethane and dichloroethane, or not at all. Therefore, it saves the cost of the process by reusing the solvent when using the method for producing the polycarbonate, only can minimize the environmental contamination not contain trace amounts of impurities, such as tetrachloromethane, and dichloroethane, or containing no polycarbonate and to reduce the energy used to produce a polymer solution can be necessary in the drying process of solution polymerization, it is possible to increase the production of the polycarbonate prepared the same energy.
