Embodiment 1
[0030] Put 2mol of 1-ethyl-3-methylimidazolium bromide and 6mol of isopropanol in a three-necked flask with reflux condensation, stir and heat at 80°C for 30min, and obtain mixture i after cooling; mix 2g of anhydrous magnesium acetate, 0.5g of Aqueous zinc acetate and 100g of mixture i were placed in a three-necked flask with reflux condensation, stirred and heated at 80°C for 30min, and cooled to obtain mixture ii; sulfuric acid with a concentration of 98wt% was added dropwise to mixture ii under vigorous stirring to make the mixture pH is 6.0, the mixture iii is obtained after cooling; the mixture iii is vacuum-dried at 80° C. for 30 min, and the desired catalyst is obtained after cooling.
[0031] Add the above 1.0g catalyst to 100g methyl laurate, and put it into a 1L autoclave while stirring; the autoclave is heated to 80°C, vacuum-dried for 10min, and then replaced with high-purity nitrogen for 3 times, and the temperature is raised to 150°C. Introduce EO, keep the temp...
Embodiment 2
[0034] Put 2mol of 1-ethyl-3-methylimidazolium bromide and 6mol of isopropanol in a three-necked flask with reflux condensation, stir and heat at 80°C for 30min, and obtain mixture i after cooling; mix 2g of anhydrous magnesium acetate, 0.5g of Water cadmium acetate and 100g of mixture i are placed in a three-necked flask with reflux condensation, stirred and heated at 80°C for 30min, and cooled to obtain mixture ii; the sulfuric acid with a concentration of 98wt% is added dropwise to mixture ii under vigorous stirring to make the mixture pH is 6.0, the mixture iii is obtained after cooling; the mixture iii is vacuum-dried at 80° C. for 30 min, and the desired catalyst is obtained after cooling.
[0035]Add the above 1.0g catalyst to 100g methyl laurate, and put it into a 1L autoclave while stirring; the autoclave is heated to 80°C, vacuum-dried for 10min, and then replaced with high-purity nitrogen for 3 times, and the temperature is raised to 150°C. Introduce EO, keep the te...
Embodiment 3
[0038] Put 2mol of 1-ethyl-3-methylimidazolium bromide and 6mol of isopropanol in a three-necked flask with reflux condensation, stir and heat at 80°C for 30min, and obtain mixture i after cooling; mix 2g of anhydrous barium acetate, 0.5g of Aqueous zinc acetate and 100g of mixture i were placed in a three-necked flask with reflux condensation, stirred and heated at 80°C for 30min, and cooled to obtain mixture ii; sulfuric acid with a concentration of 98wt% was added dropwise to mixture ii under vigorous stirring to make the mixture pH is 6.0, the mixture iii is obtained after cooling; the mixture iii is vacuum-dried at 80° C. for 30 min, and the desired catalyst is obtained after cooling.
[0039] Add the above 1.0g catalyst to 100g methyl laurate, and put it into a 1L autoclave while stirring; the autoclave is heated to 80°C, vacuum-dried for 10min, and then replaced with high-purity nitrogen for 3 times, and the temperature is raised to 150°C. Introduce EO, keep the tempera...
