General description
Thermal decomposition of dipropyl carbonate at 300-400°C yields carbon dioxide, alkene and alcohol. Dipropyl carbonate reacts with hydrous titanium dioxide (TiO2 ·nH2O, n=0.15-1.23) at 453-573K to yield titanium tetraalkoxides [Ti(OPrn)4]. N435-catalyzed transesterification of diethyl carbonate with dipropyl carbonate to form ethyl propyl carbonate has been reported.
