Phenylacetone is called MDP2P (3,4-methylenedioxy phenyl-2-propanone) which is used in the clandestine synthesis of MDMA (3,4-methylenedioxymethamphetamine), commonly known as ecstasy.

Synthesis of Acetone peroxide – Thomas' Chemistry

Acetone Peroxide can be made from common easily obtainable items - Acetone, Hydrogen Peroxide and a catalyst such as sulphuric acid. AP is usually used as a primary explosive (detonator) and never used as a main filler explosive, due to it's sensitivity. AP will easily detonate in contact with fire, heat or friction. When ignited in small amounts, it creates a large fireball. When confined or large amounts are used, it detonates without any flame. AP is one of the most friction sensitive explosive known, and great care is needed to handle this explosive. Furthermore, as with other explosive peroxides, AP is very volatile. If left 10 days at RTP, almost 50% of the sample will completely volatize. Due to it's vaporizable nature, it would have to be used almost immediately after manufacture. Mixtures of R.D.X. and Picric acid with acetone peroxide are reported to be used between primary explosive and the base charge. Mixtures such as picric acid / acetone peroxide (40/60) or similar mixtures with R.D.X. and P.E.T.N. will give explosives greatly increased resistance to impact without losing much performance. These dried crystals would be ready to load into detonators for immediate use as the storage stability is not very good.

Carbon-11 labeled acetone is a useful radiosynthetic precursor

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.
