Solvent-free synthesis of cyclic carbonates

Pyo, Sang Hyun LU orcid ; Persson, Per ; Lundmark, Stefan and Hatti-Kaul, Rajni LU (2011) WO2011159219A1
Abstract
Disclosed is a process for production of a cycloaliphatic carbonate from a diol, triol or polyol and a carbon dioxide source, such as a dialkyl carbonate. Said process is performed in a solvent-free medium using a N-heterocyclic carbene or N-heterocyclic carbene complex as catalyst. Said N-heterocyclic carbene or carbene complex is preferably attached to a lipase. Said process comprises preferably a transesterification step and a thermal disproportionation step and yielded cycloaliphatic carbonate is in preferred embodiments a monocyclic carbonate having a five-membered or a six-membered ring.
