Process for producing cyclosiloxanes from silicone waste

Abstract

The invention relates to a process for producing at least one cyclosiloxane by catalyzed depolymerization of silicone waste comprising or consisting of the steps: (i) dissolving at least a portion of the silicone waste in at least one solvent containing or consisting of at least one aliphatic hydrocarbon (K) using at least one depolymerization catalyst (D1), (ii) optionally deactivating the at least one depolymerization catalyst (D1) and adding at least one further depolymerization catalyst (D2), (iii) distillative removal of the at least one cyclosiloxane from the mixture, characterized in that the at least one aliphatic hydrocarbon (K) comprises at least 16 carbon atoms.
