Embodiment 1
[0034] The processing method of cyproterone acetate mother liquor thing, flow chart is as figure 1 As shown, the specific steps are as follows:
[0035] Take diatomaceous earth and silica gel and fill them into filter cartridges with appropriate diameters in sequence. First fill in silica gel with a height of about 0.8m, add filter cloth and then fill with diatomite with a height of about 0.2m; after taking the concentrated dry solvent produced by CPA industry 10kg of the oily mother liquor, add mixed solvent 15kg (dichloromethane: sherwood oil=1:8, volume ratio) carry out normal pressure filtration after stirring and dissolving, add 40kg same mixed solvent after filtering and wash, washing liquid and filtrate merge , respectively collect the combined solution and the silica gel layer;
[0036] The combined solution was concentrated to dryness to obtain a combined solution concentrate, which was stored for future use. Soak and wash the silica gel layer with an appropriate am...
Embodiment 2
[0039] The processing method of cyproterone acetate mother liquor thing, concrete steps are as follows:
[0040] Take diatomaceous earth and silica gel and fill them into filter cartridges with suitable calibers in turn, first fill in silica gel with a height of about 0.7m, add filter cloth to isolate, and then fill with diatomite with a height of about 0.2m; after taking the concentrated dry solvent produced by CPA industry 10kg of the oily mother liquor, add mixed solvent 18kg (chloroform: hexanaphthene=1:10) and stir and dissolve and carry out normal pressure filtration, add the mixed solvent of 50kg same proportion after filtering and wash, washing liquid and filtrate merge, Collect the combined solution and the silica gel layer respectively;
[0041] The combined solution was concentrated to dryness to obtain a combined solution concentrate, which was stored for future use. The silica gel layer was soaked and washed with an appropriate amount of methanol for 3 times, the...
Embodiment 3
[0044] The processing method of cyproterone acetate mother liquor thing, concrete steps are as follows:
[0045] Take diatomaceous earth and silica gel and fill them into filter cartridges with appropriate diameters in turn, first fill in silica gel with a height of about 0.5m, add filter cloth to isolate, and then fill with diatomite with a height of about 0.3m; after taking the concentrated dry solvent produced by CPA industry 10kg of the oily mother liquor, add mixed solvent 20kg (dichloromethane: n-hexane=1:10) and stir and dissolve, carry out normal pressure filtration, add 60kg mixed solvent of the same proportion after filtering and wash, washing liquid and filtrate merge, respectively Collect the combined solution and the silica gel layer;
[0046] The combined solution was concentrated to dryness to obtain a combined solution concentrate, which was stored for future use. Soak and wash the silica gel layer with an appropriate amount of methanol for 3 times, combine th...
