Embodiment 1
[0015] Add 19.21 g citric acid (0.1 mol), 33.35 g n-butanol (0.45 mol) and 0.38 g (NH 4 ) 0.5 Ag 0.5 h 2 PW 12 o 40 Catalyst, start stirring, raise the temperature to 155°C, start timing when the reflux phenomenon starts to appear in the condenser tube, and react for 4 hours. After the reaction system was cooled to room temperature, it was separated by filtration, and the filtrate was detected by gas chromatography. The product yields are shown in Table 1.
Embodiment 2
[0017] Using the same reaction conditions and detection method as in Example 1, only the amount of catalyst was changed to 0.20 g, and the product yield is shown in Table 1.
Embodiment 3
[0019] Using the same reaction conditions and detection method as in Example 1, only the amount of catalyst was changed to 0.80 g, and the product yield is shown in Table 1.
