“…The mechanisms of the reaction have been studied and proven by many researchers [21,23]. As analyzed by the GC-MS method in this work, the main products in the one-pot reaction from CO2, ethanol and PO were 1,2-propanediol (PG), DEC and propylene carbonate (PC) with the side-product 1-ethoxy-2-propanol (EP).…”

The EP might be formed from propylene oxide by ethanolysis [23,24] in the basic catalytic environment. The possible equations of these reactions are presented as follows (Scheme 1).…”

Abstract:One-pot syntheses of diethyl carbonate (DEC) from CO 2 , propylene oxide and ethanol were carried out using different solid catalysts. The supercritical CO 2 extraction method was used to separate the liquid products and reactants from the catalysts after reaction. The KNO 3 -CeO 2 and KBr-KNO 3 -CeO 2 were found to be active for the reaction after calcinations. The catalyst was also reusable. The thermodynamic properties of the reaction were also evaluated. The effects of various conditions, such as reaction time, amount of catalysts, molar ratio of the reactants, the composition and calcination temperature of the catalysts on the conversion and yields, were investigated, and the yield of DEC was about 13.0% with a selectivity of 38.5% over KBr-KNO 3 -CeO 2 . The yield of DEC was improved about 10-fold by using KBr-KNO 3 -CeO 2 catalyst compared to CeO 2 .

“…Huang [284] has reported details of the synthesis of DMC using KI, K 2 CO 3 , KOH, and NaOH supported on MgO or ZnO as catalysts in scCO 2 . Both the KI/ZnO and K 2 CO 3 -KI/ZnO combinations were shown to produce good catalysts, with complete conversion of epoxides being achieved in 4 h, with a high selectivity.…”

“…Unfortunately, this method is not successful because of the large amount of the by-products produced from the alcoholysis of epoxides (Scheme 2, second line) [16][17][18] . Therefore, the key to carry out the one-pot reaction is that the catalyst should be active for both the reactions Unauthenticated Download Date | 5/10/18 6:44 AM bomb before and after charging.…”

The improved one-pot synthesis of dimethyl carbonate and propylene glycol from propylene oxide, supercritical carbon dioxide, and methanol with potassium bicarbonate as the catalyst has been reported in this paper. As far as we know, it is the fi rst time to use potassium bicarbonate only as the catalyst in the production process which is simple and cheap. Satisfactory conversion rate of propylene oxide and yield of the products could be achieved at the optimized conditions with quite a small amount of by-products. Our new method offers an attractive choice for the production of dimethyl carbonate in large-scale industry effi ciently and environmental friendly.
