There is a middle ground. If you dissolve the phenidone and ascorbic acid in propylene glycol to make a stock solution, you can use it with TEA or any other alkali that turns you on. If you like the results you get with TEA, you can mix it with the glycol stock to form a new single solution stock without losing any storage life and without the discoloration that comes from heating TEA too much. Instead of 1+50, use 1+25.
