Synthesis of Methyl propyl carbonate (cas 1333-41-1) via gas-phase transesterification over TiO2/Al2O3

Add time:08/17/2019    Source:sciencedirect.com

A heterogeneous catalyst, TiO2 supported on Al2O3 was used for the synthesis Methyl propyl carbonate (cas 1333-41-1) (MPC) by the transesterification of dimethyl carbonate (DMC) and propanol. The morphological and chemical states of titanium species in TiO2/Al2O3 were characterized by means of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and CO2-TPD, respectively. The effect of reaction conditions, such as temperature, gaseous hourly space velocity (GHSV), and the molar ratio of propanol/DMC on the reaction were discussed. The results showed that under the optimized reaction conditions, the reaction temperature 403 K, the molar ratio of propanol/DMC of 0.5:1, and a GHSV 360 h−1, the conversion of DMC was 62%, the yields of MPC was 51%.
