o-Chloranil Use and Manufacturing
Pentachlorophenol is obtained by reacting with nitric acid in chloroform. Suspend dry pentachlorophenol in chloroform, slowly add nitric acid at 15-17℃, react for half an hour at 20-25℃, add water, cool to below 10℃, filter, and let the filtrate stand to remove the water layer and wash with water Bring the chloroform layer to pH 6-7, recover the chloroform to dryness under reduced pressure, add 0.4 times benzene, heat to dissolve, add 0.4 times gasoline, cool, filter, wash with cold benzene-gasoline, and recrystallize with benzene-gasoline to get four Chloro-o-benzoquinone.
The raw material of the contraceptive pill medroxyprogesterone.
