Done exactly like in the video, except adding 62.5ml of 80% acetic acid. At the beginning I was worried about acid concentration s obas of the age and quality of P2NP (about 10 months in jar, got little oily wet). l've failed Al/Hg recipe from "scribd" site three times, si i was hopeless. But reaction was so vigorous that I had to rinse condenser with additional 20ml IPA. I've dried 99% acetone over molecular sieve baked 300°C, but somehow after adding 96% sulphuric acid it turned into brown thick goo. So I had to acidify it phosphorous way. Final product is very potent, yield is 7.2g dry from 10.3g P2NP. In the next week I'd take a sample to my workplace and take a quality shot on GC-MS/MS.
Also, I'm curious if I can replace GAA with different acid eg. formic? The smell of spilled 80% vinegar is horrible
