lets assume were staring with 100g of Safrole
to that we add 5g of KOH, and get about 95g of isosafrole and 10g of tar back.
forming the epoxide via Oxone of the remaining 95g of Isosafrole, we need 1.2L(1kg) of methanol, 3L(3kg) of water, 450g of Oxone, and 150g of sodium bicarbonate. You will also need 450g of DCM to extract if you wash your water afterwards(optional, but recommended for yeild. You better be reclaiming all of your DCM!)
to rearrange the 85g of epoxide to ketone, we will need ~1L(1.15kg) of 15% sulfuric acid, 700ml (600g?) of ether, 2L (2kg) of water and ~50g of sodium hydroxide for washes.
reductive amination of ketone to MDMA is the real killer though. We'll base our numbers around a nitromethane Al/Hg on 55g ketone return from before. you'll use 116g of aluminum foil, 45ml(50g) of nitromethane, 2L(1.6kg) of methanol, and 400mg of HgCl2 (ouch!). for extraction, you will need 1.5L(1.5kg) of water and 550g of sodium hydroxide, 1L(900g?) of toluene(which will be reclaimed), 6L (6kg) of water and 50g of NaCl for washes. After adding ~20g of muriatic acid, you will have ~40g of crystals.
Time to recap:
100g of safrole
5g of KOH
1000g + 1600g Methanol
3000g + 900g + 2000g + 1500g +6000g Water
450g Oxone
150g Sodium Bicarbonate
150g Sulfuric acid
600g ether
50g + 55 g sodium hydroxide
50g nitromethane
115g aluminum
0.4g mercuric chloride
20g hydrochloric acid
50g table salt
so to make 40g of MDMA, you produce ~18kg of waste. not counting water (all water get contaminated when waste is disposed of recklessly, so it's kind of a mute point), we end up with ~4.4kg of waste for 40g of MDMA, or a ratio of 110:1 product to waste.
In other words, that retard playing the rave video game is working harder than OPEC to fuck up the environment.
