Zusammenfassung:	The present invention relates to a process for hydrolysis of carbonates, in particular polycarbonates, in the presence of at least one phase-transfer catalyst. The process according to the invention makes it possible to recover valuable raw materials from industrially produced carbonates, in particular polycarbonates, once these have fulfilled their original intended purpose. It thus avoids a loss of such raw materials, such as would arise in the event of disposal by incineration or landfill for instance.
