Ingredients needed for 1,5kg of Picric Acid secondary/booster

1. 10 liters of 90%+ sulfuric acid (requires 2 days of labour, cost: aprox 200 euro)

2. 1,6 kg of Acetylsalicylic acid (requires 4 days + 2 days of labour, cost: aprox 1500 euro)

3. 3 kg of Sodium Nitrate (pre-ordered at apothecary, 1 week delivery time, cost: aprox 500 euro). This can also be synthesized relatively easily if you are having trouble buying it.

4. 80 liters of distilled water/distilled ice cubes (cost: aprox 440 euro)

1. 10 liters of 90%+ sulfuric acid

Estimated time required: 1-3 days to purchase the product (28-37%) and it requires 2-3 days of labour to concentrate it to 90%+.

Boiling down 35 liters of un-concentrated sulfuric acid (28-37%) to 10 liters of 90%+ concentration

In order to concentrate sulfuric Acid bought from stores (containing 28-37%) you will have to boil down the liquid. In order to get 10 liters of 90%+ sulfuric acid you need approximately 30 liters containing 28-37%.

I bought a container of 25 liters (28%) from one supplier (supplies car shops etc) and I bought 5 bottles from 3 other retailers each containing 1 liter. I also bought 4 car batteries in case I needed more.

I was uncertain how I should approach the "boiling down process" at first. The guides I had reviewed suggested you use specialty hot-temperature porcelain plates, use of specialty lab beakers, use of cooking stones to prevent sprouting and to use all necessary protection gear. As such; I assumed you needed specialty cooking plates that could reach very high temperatures and that I would need boiling stones and specialty laboratory glassware that could sustain extreme temperatures. Needless to say; the guide was wrong on all accounts! You don't need any of this to concentrate sulfuric acid! Not hot-temperature porcelain plates (any plates will do), not specialty lab beakers (any regular Duran lab beakers will do) and not boiling stones (I tried with boiling stones and it made it harder).

I initially bought 3 induction plates (flat porcelain) but they didn't function as my 2L beakers didn't cover the minimum diameter required for the induction plates to function. I used standard inexpensive lab beakers made from Duran glass btw. I also broke two other beakers made from Duran glass (crushed them to small pieces with a hammer under a towel) in order to use it as boiling stones (to prevent the liquid from sprouting).

As the induction plates didn't work for me I purchased 2 regular single cooking plates; the more expensive ones with iron plates retailing for 140 euro a piece. I had a very cheap single plate from before. Using the boiling stones was a failure for me so I reduced the amount of stones until I decided to remove them all and try without. I was also unsure how to store the concentrated sulfuric acid once I was done boiling. Some sources said glass was required while other said you needed specialty plastic. This was incorrect, as I stored my 90-95% acid in regular plastic bottles, in both 1 liter bottles (the bottles which were intended for 28% sulfuric acid) and 4 liter bottles (bottles produced for distilled water). I encountered absolutely no problems doing this whatsoever (I had them in these bottles for up to 6 weeks).
