synthesis of potassium picramate with sugar
In a beaker with 1000 ml water dissolve 20 g of picric acid and heat to 80 C with a magnetic stirrer. Than in small amounts add 25 g of sodium
carbonate and let dissolve all. (fumes bubble of) than add to the mixture 30 g of sugar and heat the mixture additional 60 minutes. The colour must go
to red brown.
Than cool to 0-1 C for 4 hours and filter out the brown neddles of potassium picramate and wash with a little amount of destilled water (water
solouble).
the synthesis can be used for the potassium picrate synthesis without the addition of sugar !

No need to get angry....
Anger management...
One shouldn't accept or resort to the mutilation of science to appease the mentally impaired.
