Sodium nitrite is really easy to make if you have access to nitric acid and a small chemistry lab. Its all about the nitric acid, every step calls for nitric acid.
Basically you react sodium bicarbonate with nitric acid, and that makes sodium nitrate. You can heat the nitrate in a pan until it melts, then add powdered charcoal. They have an exothermic reaction akin to gunpowder that produces CO2 and leaves behind impure nitrite but also some unreacted nitrate and maybe some sodium oxide. You dissolve this powder in water and add some sodium bicarbonate to neutralize the sodium oxide, then boil the water the liquid and dissolve again but in pure ethanol. Some solids will be left behind, unable to dissolve in ethanol, sodium carbonate and bicarbonate. The remaining liquid will be a mixture of nitrate and nitrite in ethanol which can be boiled off.
To analyze the nitrite/nitrate ratio you can take a small amount of powder, say 1 gram, as a sample and dissolve in water. Then you add some silver nitrate, in excess. This silver nitrate will turn the sodium nitrite into silver nitrite, which is not soluble in water and will sink to the bottom. Carefully rinse the water and weight the remaining dry powder, you'll get 1 molecule of silver nitrite for each molecule of sodium nitrite present in your sample. This wont help you purify anything, just tells you what the purity is. Silver nitrate is made by reacting silver metal or silver nitrite with nitric acid, so it can be recycled after the test.
One laborious way of purifying sodium nitrite is by taking advantage of its 10% lower solubility in water compared with sodium nitrate. Dissolve an excess of a mixture of nitrite/nitrate salts in water and the nitrates will dissolve a bit easier than the nitrites. Rinse off the water and repeat, with each wash the nitrite concentration will get progressively closer to 99%, but will lose a great deal of salts with each wash (though these can be recycled). You can also do the reverse and start from a "still available-not yet banned" product like Prague powder #1, which is 6.25% sodium nitrite and 93.75% table salt. Dissolve this in pure ethanol, the table salt will not dissolve at all but the nitrite will. Rinse off the liquid and boil it off, leaving pure nitrite.
Nitric acid itself is a controlled substance but it can be inefficiently made at home with a high voltage source, as used to power neon signs, by burning atmospheric nitrogen with a very hot electric arc, and bubbling nitrogen dioxide in water. The same process happens in nature with lighting and was used industrially in the early 20th century.
I wish i knew how to make Fentanyl.
