YieldReaction ConditionsOperation in experiment
54.8% at 130℃; for 8 h; Autoclave; High pressure General procedure: The one-step synthesis of DMC from carbon dioxide, epoxides and methanol was carried out in a sealed Teflon-lined stainless steel high pressure autoclave with inner volume of 50mL provided with a magnetic stirrer and an electric heater. Typical conditions and procedures are described as follows: a certain amount of methanol, propylene oxide (PO), catalyst and cocatalyst were added into the above autoclave. Alkali halides were used as catalysts, several typical crown ethers (i.e., [2,4],-dibenzo-18-crown-6 (DBC), 18-crown-6, 15-crown-5 and 12-crown-4) were used as cocatalysts, and polyethylene glycol (MW=4000, abbreviated as PEG4000) was used as comparison for the crown ether. Then CO2 (gas, > 99.99percent) was injected up to a certain pressure at room temperature. The autoclave was heated to a certain temperature and the mixture was stirred at that temperature for several hours. After the reaction, the autoclave was cooled to about 10°C with ice-water mixture and then depressurized. The liquid reaction mixture was analyzed by gas chromatograph (GC 2060) equipped with a capillary column (HP-INNOWAX, 30m×0.32mm×0.25μm) and flame ionization detector (FID) using n-butyl alcohol as an internal standard, and further identified by gas chromatography-mass spectrometry (Agilent 7890-5975C) by comparing retention times and fragmentation patterns with authentic samples. The temperature of the GC column was set at 60°C for 3min and then was programmed to rise to 80°C at the rate of 5°Cmin−1, and further reached 220°C at the rate of 30°Cmin−1 and remained at that temperature for 3min.

YieldReaction ConditionsOperation in experiment
11.8 %Chromat. at 60℃; for 12 h; Autoclave; Supercritical conditions General procedure: PO synthesis reaction from propylene in presence of ex situ H2O2, as oxidizing agent, were performed in a 3 mL round bottom glass reactor in which the stirring was driven by a Teflon-coated magnetic stirrer. Known amounts of TS-1 catalyst (2.5 mg), methanol (1.2 g), and propylene (9 mmol) were added, followed by the addition of the oxidant, 35percent wt H2O2 in water (0.4 mmol). Then, the mixture was heated at 60°C, and the reaction was monitored for 5 h. The experiments for the direct synthesis of PO with in situ generated H2O2 were carried out in a 15 mL stainless steel reactor which contained a relief valve, for safety. The stirring was driven by a Teflon-coated magnetic stirrer. Known amounts of catalyst (15 mg), acidity inhibitor (ammonium acetate, 0.01 g) and co-solvent (0.2 gof different co-solvents) were added to the reactor, followed by the addition of propylene (2 mmol) and CO2, reaching carbon dioxide vapor pressure (>55 bar). Oxygen and hydrogen were added to the reactor by means of high pressure burettes, and then the reactor was heated up to desired temperature (ranging from room temperature to 80°C, according each experiment). The reaction experiments were carried out for 5 h, unless otherwise stated. At the end of the reaction, the reactor was cooled down and the pressure was slowly released by venting, accumulating the gaseous mixture in an inert gas sampling bag. 3-pentanone was used forrecovering any product that could be retained on the reactor walls. The amount of formed products, i.e., propylene oxide, acetone, propionaldehyde, acrolein, isopropanol, 1-methoxy-2-propanol (MP1), 2-methoxy-1-propanol (MP2), propylene glycol (PG) and propylene carbonate were analyzed using a Shimadzu Gas chro-matograph GC-2010 Plus provided with FID detector and 20 m length, 0.10 mm ID, 0.10 m df. Permabond FFAP column. The amounts of propane and unreacted propylene, oxygen and hydrogen were analyzed using a Bruker 450-GC which contains two different independent channels. The first one is provided with a thermal conductivity detector (TCD) and three different columns: Hayesep N (0.5 m length), Hayesep Q (1.5 m length) and molsieve 13× (1.2 m length), using argon as carrier. The second one is provided with two different flame ionization detectors (FID) and three different columns: capillary column CP-Wax (1 m length and 0.32 mm ID), CP-Porabond Q (25 m length and 0.32 mm ID) and CP-Wax (5 m length and 0.32 mm ID).

YieldReaction ConditionsOperation in experiment
17.6 %Chromat. at 60℃; for 7 h; Autoclave; Supercritical conditions General procedure: PO synthesis reaction from propylene in presence of ex situ H2O2, as oxidizing agent, were performed in a 3 mL round bottom glass reactor in which the stirring was driven by a Teflon-coated magnetic stirrer. Known amounts of TS-1 catalyst (2.5 mg), methanol (1.2 g), and propylene (9 mmol) were added, followed by the addition of the oxidant, 35percent wt H2O2 in water (0.4 mmol). Then, the mixture was heated at 60°C, and the reaction was monitored for 5 h. The experiments for the direct synthesis of PO with in situ generated H2O2 were carried out in a 15 mL stainless steel reactor which contained a relief valve, for safety. The stirring was driven by a Teflon-coated magnetic stirrer. Known amounts of catalyst (15 mg), acidity inhibitor (ammonium acetate, 0.01 g) and co-solvent (0.2 gof different co-solvents) were added to the reactor, followed by the addition of propylene (2 mmol) and CO2, reaching carbon dioxide vapor pressure (>55 bar). Oxygen and hydrogen were added to the reactor by means of high pressure burettes, and then the reactor was heated up to desired temperature (ranging from room temperature to 80°C, according each experiment). The reaction experiments were carried out for 5 h, unless otherwise stated. At the end of the reaction, the reactor was cooled down and the pressure was slowly released by venting, accumulating the gaseous mixture in an inert gas sampling bag. 3-pentanone was used forrecovering any product that could be retained on the reactor walls. The amount of formed products, i.e., propylene oxide, acetone, propionaldehyde, acrolein, isopropanol, 1-methoxy-2-propanol (MP1), 2-methoxy-1-propanol (MP2), propylene glycol (PG) and propylene carbonate were analyzed using a Shimadzu Gas chro-matograph GC-2010 Plus provided with FID detector and 20 m length, 0.10 mm ID, 0.10 m df. Permabond FFAP column. The amounts of propane and unreacted propylene, oxygen and hydrogen were analyzed using a Bruker 450-GC which contains two different independent channels. The first one is provided with a thermal conductivity detector (TCD) and three different columns: Hayesep N (0.5 m length), Hayesep Q (1.5 m length) and molsieve 13× (1.2 m length), using argon as carrier. The second one is provided with two different flame ionization detectors (FID) and three different columns: capillary column CP-Wax (1 m length and 0.32 mm ID), CP-Porabond Q (25 m length and 0.32 mm ID) and CP-Wax (5 m length and 0.32 mm ID).
