Deuterated acetone
Deuterated acetone ((CD3)2CO), also known as Acetone-D6, is a form (called an isotopologue) of acetone (CH3)2CO in which the hydrogen atom ("H") is replaced with deuterium (heavy hydrogen) isotope ("D"). Deuterated acetone is a common solvent used in NMR spectroscopy.

Properties
As with all deuterated compounds, the properties of deuterated acetone are virtually identical to those of regular acetone.
Manufacture
Deuterated acetone is prepared from heavy water, D2O, by what amounts to an aldol reaction. In this case, the base used is a deuterated version of lithium hydroxide:[1]

In order to fully deuterate the acetone, the process is repeated several times, distilling off the acetone from the heavy water, and re-running the reaction in a fresh batch of heavy water.
gollark: Your personal computer probably has basically as much single-threaded performance as the best available ones now, give or take 40%, which is actually quite substantial but oh well.
gollark: That probably doesn't help if your thing isn't already parallel.
gollark: GPU acceleration is hard. Running mostly independent things in parallel on CPU probably isn't.
gollark: Does Matlab have some kind of profiler to find the slowest bits?
gollark: Can you evaluate each configuration in parallel in the genetic algorithm bit?
