Differences in Density for TATP/DADP: Is the Dimer Form More Unstable?

AI Thread Summary
The discussion revolves around the storage and stability of triacetone triperoxide (TATP) in water, with observations about the density of the substance causing some of it to float while the rest sinks. The user speculates that the presence of a dimer form of acetone peroxide (AP) could explain this behavior, noting its lower density compared to the trimer form. They express interest in separating and testing the two forms for stability characteristics. However, the conversation is quickly redirected as participants emphasize that discussions about explosives are not permitted, and one member questions the validity of the density calculations provided. The thread is subsequently locked due to the topic's nature.

I have recently been experimenting with triacetone triperoxide (tatp), and I have been storing it under water since that is the only way it is stable. However, I have noticed that most of the powder suspended in water is clearly denser than the water, and about a fifth of it is floating on top of the water. I am guessing that the process to make the tatp yields some of the dimer form of the AP, which is about 148.157g/mol, which is slightly less than 1g/cm3 which would explain it floating on the water, whereas the trimer of AP is about 222.24g/mol, which would make it denser than 1g/cm3, thus causing it to sink. I am curious about this because the dimer is way more unstable than the trimer, and could be worth skimming the dadp off of the top and storing it separately, and do some small scale testing and comparing the friction, heat, and shock sensitivity of each. Input would be greatly appreciated! :) -Zak

1. We don't discuss explosives here.

2. I am not aware of any sure way of converting molar masses to densities, so I don't see where your numbers come from. But it is a moot in the light of the point 1.

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
