99% Isopropyl for dissolving Glycin??greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread
Just finished mixing a batch(1000 mL) of PF FX-2 developer pt.A (FX2 is a 2-part developer). 50mL of 99% ISO Alcohol was used to help dissolve the Glycin. My question is whether or not this is too much (99% ISO)alcohol for the solution. I can smell alcohol in the finished solution, and I was wondering what, if any, ways this could affect the results. Your responses are greatly appreciated.

That would work out to 2.5mL to every litre of working solution. And why would Benzyl (alcohol) be better?

Crawley recommends 50ml of isopropyl alcohol, if the glycin won't dissolve in the solution after 3 minutes of stirring. He recommends boiling the water first, then cooling to 30 degrees C. I tend to think it would dissolve if the glycin were fresh, but I've never tried to mix FX-2, and solution A may not be alkaline enough.
