Embodiment 1
[0066] exist figure 1 Carry out the preparation of isobutyric acid in the shown device, at first in reactor 1, be filled with 2 kilograms of oxygen through gas feed pipe 2, the mixed emulsion of isobutyraldehyde and water (the content of isobutyraldehyde in the mixed solution is 50% by weight ) enters the liquid distributor 8 in the reactor 1 through the liquid feed pipe 2 through the feed pump 21; the circulation pump 31 pumps the gas in the upper part of the reactor 1 into the gas distributor 9 by the gas circulation line 7; the liquid distributor 8 The isobutyraldehyde-water mixture coming from the gas distributor 9 is driven by oxygen and sprayed into the reaction kettle 1 through the atomization unit 5 (specifically, the atomization nozzle) for rapid oxidation. The temperature in the reaction kettle 1 is 80°C and the pressure is 0.25°C. MPa, the reaction time is 2h. The liquid at the bottom of the reaction kettle 1 is discharged through the discharge pipe 4 for oil-water...
Embodiment 2
[0069] First, 8 kilograms of oxygen are charged into the reactor 1 through the gas feed pipe 2, and the mixed emulsion of isopropanal and water (the content of isobutyraldehyde in the mixed solution is 60% by weight) is passed through the feed pump 21 by the liquid feed pipe 2. Enter the liquid distributor 8 in the reactor 1; the circulation pump 31 pumps the upper gas in the reactor 1 into the gas distributor 9 through the gas circulation line 7; the isobutyraldehyde water coming from the liquid distributor 8 and the gas distributor 9 is mixed The liquid is driven by oxygen and sprayed into the reaction kettle 1 through the atomization unit 5 (specifically, the atomization nozzle) for rapid oxidation. The temperature in the reaction kettle 1 is 30° C., the pressure is 0.25 MPa, and the reaction time is 3 hours. The liquid at the bottom of the reaction kettle 1 is discharged through the discharge pipe 4 for oil-water separation, and the isobutyric acid contained in the water ph...
Embodiment 3
[0072] At first in reactor 1, be charged with 5 kilograms of oxygen through gas feed pipe 2, the mixed emulsion of isopropanal and water (the content of isobutyraldehyde in the mixed solution is 70% by weight) by liquid feed pipe 2 through feed pump 21 Enter the liquid distributor 8 in the reactor 1; the circulation pump 31 pumps the upper gas in the reactor 1 into the gas distributor 9 through the gas circulation line 7; the isobutyraldehyde water coming from the liquid distributor 8 and the gas distributor 9 is mixed The liquid is driven by oxygen and sprayed into the reaction kettle 1 through the atomization unit 5 (specifically, the atomization nozzle) for rapid oxidation. The temperature in the reaction kettle 1 is 50°C, the pressure is 0.4MPa, and the reaction time is 3h. The liquid at the bottom of the reaction kettle 1 is discharged through the discharge pipe 4 for oil-water separation, and the isobutyric acid contained in the water phase is further separated.
