Embodiment 1
[0013] Measure absolute ethanol with a molar ratio of 5:2:3, tetrabutyl titanate, and nitric acid with a concentration of 1mol / L. Then add the solution dropwise to the above-mentioned nitric acid, stir vigorously to form a transparent solution, then adjust the pH value to 2 with a NaOH solution with a concentration of 0.5mol / L, and stir fully at the same time until a transparent solution is formed. use. Take the purified bentonite, the amount of which is 8 times the number of moles of tetrabutyl titanate, and fully infiltrate it with water, then add cetyltrimethylammonium bromide, whose mole number is 10 times that of bentonite, and react for 12 hours after fully stirring , then add dodecylamine whose molar number is 10 times that of bentonite, continue to react for 24 hours, mix it with the transparent solution prepared above, stir vigorously at 80°C for 2 hours, and then add a molar amount of tetrabutyl titanate 0.5 times the magnesium nitrate and copper nitrate of the este...
Embodiment 2
[0015] Measure absolute ethanol with a molar ratio of 15:5:3, tetrabutyl titanate, and nitric acid with a concentration of 1mol / L. Then add the solution dropwise to the above-mentioned nitric acid, stir vigorously to form a transparent solution, then adjust the pH value to 2 with a NaOH solution with a concentration of 0.5mol / L, and stir fully at the same time until a transparent solution is formed. use. Take the purified bentonite, the amount of which is 20 times the number of moles of tetrabutyl titanate, and fully infiltrate it with the same quality of water, then add cetyltrimethylammonium bromide, whose number of moles is 5 times that of bentonite, and stir thoroughly After reacting for 12 hours, add dodecylamine whose molar number is 5 times that of bentonite. After continuing to react for 12 hours, mix it with the transparent solution prepared above, stir vigorously at 60°C for 2 hours, and then add a molar amount of titanium Magnesium nitrate and copper nitrate 1.0 ti...
Embodiment 3
[0017] Measure absolute ethanol with a molar ratio of 12:3:5, tetrabutyl titanate, and nitric acid with a concentration of 1mol / L. Then add the solution dropwise to the above-mentioned nitric acid, stir vigorously to form a transparent solution, then adjust the pH value to 2 with a NaOH solution with a concentration of 0.5mol / L, and stir fully at the same time until a transparent solution is formed. use. Take the purified bentonite, the amount of which is 15 times the number of moles of tetrabutyl titanate, and fully infiltrate it with the same quality of water, then add cetyltrimethylammonium bromide, whose number of moles is 5 times that of bentonite, and stir thoroughly After reacting for 24 hours, add dodecylamine whose molar number is 10 times that of bentonite. After continuing to react for 12 hours, mix it with the transparent solution prepared above, stir and react vigorously at 80°C for 6 hours, and then add a molar amount of titanium Magnesium nitrate and copper nit...
