Keto-RDX/RDX crystal question

fredsci93 - 21-9-2021 at 16:43

Here I have multiple large crystals from acetone, these crystals were prepared by boiling a crude mix of Keto-RDX/RDX with ethyl acetate separation of the liquid, a wash, and finally what was left was dissolved in acetone and evaporated over a week or so, based on solubility I would assume all the Keto-RDX would dissolve quickly in the ethyl acetate meaning these crystals would be RDX, however, these crystals are rhombic in structure and quite sensitive (I am aware sensitivity increases with crystal size however the sensitivity is that of a primary). Has anyone here made large RDX crystals or large Keto-RDX crystals that could serve for comparison (if you want to make crystals like this I used new glassware, seed crystals, and a conical evaporator) any help with characterizations would be highly appreciated.

Well, according to http://www.sciencemadness.org/talk/viewthread.php?tid=157509... k6 is more powerful than rdx, so if you had a sample of pure rdx crystals, then you could compare the two.
