Embodiment 1
[0063] As shown in the flow process of accompanying drawing, carry out rectification by the rectification condition of table 4 and table 5 after the dehydrogenation of reaction synthesis liquid, wherein the extractant of delight component tower is water, and the mass ratio of consumption and feed liquid is 3:1, added in the second theoretical plate, wherein the height ratio of packing A and packing B in the liquid-liquid stratifier on one side of the dehydration tower is 1:4, and the results are shown in Table 6. It can be seen from Table 6 that the mass fraction of MIBK product finally obtained is 99.56% through the rectification of each rectification column.
[0064] The preparation method of filler A and filler B is as follows: the stainless steel filler is put into potassium permanganate sulfuric acid solution for 18 hours, and then washed with deionized water until neutral to obtain filler A. Spray polytetrafluoroethylene emulsion and sulfonated polyimide emulsion on the ...
Embodiment 2
[0073] As shown in the flow process of accompanying drawing, carry out rectification by the rectification condition of table 7 and table 8 after the dehydrogenation of reaction synthesis liquid, wherein the extractant of delight component tower is water, and the mass ratio of consumption and feed liquid is 2:1, added in the fifth theoretical plate, wherein the height ratio of packing A and packing B in the liquid-liquid stratifier on one side of the dehydration tower is 1:1, and the results are shown in Table 9. It can be seen from Table 9 that the mass fraction of MIBK product finally obtained is 99.67% through the rectification of each rectification column. The preparation method of filler A and filler B is shown in Example 1.
