I followed the video and read through entire instruction, when I reach the point of inserting mercury nitrate solution, 5ml (from 2g Hg + 15ml nitric acid 68%), then 1 liter of cold water, I then got the result like the video, cloudy gray water and some aluminium foil rinsed up, as the video and instruction mentioned is advised to add more water after first drain, and to repeat the drain process, so i add another 1 liter of cold water

Unexpected issue:
1. it turns cloudy gray again and looks more thicker mixture than the beginning
2. then it started bigger bubbles
3. it has more heat now i tried to touch it, so I pour out again and add the third 1 liter of cold water
4. 3 mins after I pour out all the cloudy gray water, the aluminium foil react itself and produce smoke cover entire lab, the flask is so cold and has water droplets on the flask surface

should I pour P2NP solution directly after the first cloudy gray water drain? because the later reaction seems like the reactions of adding P2NP in the video

No problem, the amalgam is ready, and you can pour a solution of phenylnitropropene.
Or, to gain experience with the first synthesis, you can not wash from mercury salts in order to clearly see the process of the chemical reaction

i had successfully reach the stage on all foil rise up and covered with small bubbles, in cloudy gray water

A



then I drain the water from it through a fine sieve

then instructions say advisable to add water again in order to rinse the amalgam from residues of mercury nitrate

so I added cold tap water, the reaction started to get more and bigger bubbles, and that is how the mass goes wrong

so I having thoughts on this stage:

No problem, the amalgam is ready, and you can pour a solution of phenylnitropropene.
1. if the amalgam is ready, shouldn't drain out and add more cold distilled water to rinse out residues of mercury nitrate?

2. if we need to rinse out the mercury nitrate, I should add cold distilled water, yes?

Must drain, and pour quickly a fresh portion of clean water. But if there is little experience, do the first reactions without additional washing.

Not necessarily ice water, the main thing is pure (drinking) water

many thanks to your reply sir, will get a few experiments again

I need it for 500g amaphetamin sulfat each process.
Have you also just run out of battery in your calculator, or do you not know how to calculate it?
I can give you some advice, one mole of P2NP theoretically becomes one mole of freebase and with half a mole of sulfuric acid we get half a mole of sulfate. The actual percentage yield is calculated using this theory. The rest should be a walk in the park.
