Embodiment 1
[0022] Weigh 50 g of glycerin (chemically pure), 150 g of acetic acid (chemically pure), 100 g of n-propyl acetate (chemically pure), and Catalyst (BILE-3, alkyl imidazole sulfonate, produced by Enze Biomass Fine Chemical Beijing Key Laboratory) 10g, put into a 500ml glass reactor; the glass reactor is connected to a glass rectifier with 20 theoretical plates Tower, react at 100°C and stirring for 3 hours, control the temperature at the top of the rectification tower between 82-85°C; add 7.5g of acetic anhydride to the reaction kettle after reacting for 3 hours, continue at 100°C and stirring React for 1 hour; after the reaction finishes, open the vacuum pump at the top of the tower to maintain the vacuum of the reaction system at 50KPa, steam the reaction solvent n-propyl acetate and excess acetic acid, and use the mixture of solvent n-propyl acetate and acetic acid as the next batch of raw materials. The residue in the kettle is a mixture of catalyst ionic liquid and product...
