Examples
Embodiment 1
[0016] Example 1: Add isopropyl nitrate (20mL, 0.2mol), sodium hydroxide (6.4g, 0.16mol), water (40mL, 2.22mol) into the autoclave, heat to 140°C in the autoclave, and the pressure is 0.9MPa , start to react, after reacting for 30 minutes, cool down to room temperature, distill the reaction solution, collect fractions at 80-84°C, gas detection, the results are as attached image 3 shown, with the attached figure 1 It can be seen that the raw material isopropyl nitrate reacts almost completely, and with the attached figure 2 It can be seen that the peak at the retention time of 0.56 min is the isopropanol peak. The calculated removal rate of isopropyl nitrate is 98.4%, and the yield of isopropanol is 66.8%.
Embodiment 2
[0017] Example 2: Add isopropyl nitrate (20mL, 0.2mol), sodium hydroxide (8.8g, 0.22mol), water (80mL, 4.44mol) into the autoclave, heat to 140°C in the autoclave, and the pressure is 0.8MPa , start to react, after reacting for 30 minutes, cool down to room temperature, distill the reaction solution, collect fractions at 80-84°C, gas detection, the results are as attached image 3 shown, with the attached figure 1 It can be seen that the raw material isopropyl nitrate reacts almost completely, and with the attached figure 2 It can be seen that the peak at the retention time of 0.56 min is the isopropanol peak. The calculated removal rate of isopropyl nitrate is 99.1%, and the yield of isopropanol is 63.6%.
Embodiment 3
[0018] Example 3: Add isopropyl nitrate (20mL, 0.2mol), sodium hydroxide (12g, 0.3mol), water (100mL, 5.56mol) into the autoclave, heat to 140°C in the kettle, pressure 0.8MPa, Start the reaction, after reacting for 30 minutes, cool down to room temperature, distill the reaction solution, collect fractions at 80-84°C, and test the gaseous quality. The results are shown in the attached image 3 shown, with the attached figure 1 It can be seen that the raw material isopropyl nitrate reacts almost completely, and with the attached figure 2 It can be seen that the peak at the retention time of 0.56 min is the isopropanol peak. The calculated removal rate of isopropyl nitrate is 99.7%, and the yield of isopropanol is 64.8%.
