Re: Phenidone
Does the Phenidone break down at a certain temperature? I took the first batch (Mytol) and heated to 140F and that helped a lot. ~m ----- Original Message ----- From: "Sandy King" <sanking@clemson.edu> To: <alt-photo-process-l@usask.ca> Sent: Thursday, June 07, 2007 8:38 PM Subject: Re: Phenidone 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 100ºF. Ethylene glycol will probably work just as well, but I won't swear to it.
