Loneoceans Laboratories - Acetone Peroxide Synthesis
TATP Synthesis | Sulfuric Acid | Explosive Material
While making 6-amino-penicillanic acid -oxide, there was an explosion in our laboratory, at which time one man was injured. The cause of the accident has been found to be trimeric acetone peroxide.
When oxidized, acetone forms acetone peroxide as a byproduct, ..
The explosion of trimeric acetone peroxide was probably caused by the combined effect of static energy and friction. The static energy accumulated in man can be 30 mJ. We performed different sensitivity tests with the isolated substance. It exploded moist with an 11.5-mJ electric spark. In impact sensitivity tests, it ignited repeatedly with a weight of 2 kg from 10 cm’s height. In friction sensitivity tests, the sample ignited with a weight of 0.5 kg. The ignition sensitivity increased when the substance was dried.
Peróxido de hidrogênio
Firstly, 11ml of 30% Hydrogen Peroxide is pipetted into 10ml of Acetone in a small 100ml conical flask. A beaker can be used but I chose to use a small conical flask to reduce acetone evaporating. This was then cooled in a salt ice bath until the temperature was around 5C. Secondly, 2ml of Sulphuric Acid was added. (It is recommended to cool the acid before adding to reduce temperature rise.) This is a critical step. The acid has to be added slowly drop wise. Do Not let the temperature rise to over 10C, otherwise there will be formation of the unstable dicyclo iosmer. Temperature is held between 0 - 10C. Constantly stir solution. It's alright if the solution is yellowish. When all acid is in, the solution is stirred for another few minutes. You will see that white precipitate starts to form already. Another plus point for the conical flask is that it's easier to mix by shaking.
