Re: Phenidone



I am also concerned about over-heating so I never go over 150F. There have been some reports that phenidoine does break down over about 175F, but I don't know for sure they are accurate.

Does the Phenidone break down at a certain temperature? I took the first
batch (Mytol) and heated to 140F and that helped a lot.

You won't need to heat it very much. I use a
magnetic stirrer and the phenidone is in solution
way before the glycol gets up to 100F.

Ethylene glycol will probably work just as well, but I won't swear to it.

  You could dissolve it in propylene glycol. Should keep indefinitely.
