I just found this, on some chinese site,
i am sorry to post it here:
this was the site:

If this is indeed true, i would be proud, but i have to go,..
15 ml benzene, 15 ml acetone, 25 ml AcOH and 5 mmol(1,01 g) Mn(AcO)3
are boiled under N2 atmosphere until the color of the soln changes from dark brown Mn(AcO)3 to pink Mn(AcO)2 - approx.
1,5 h. The rxn mixtr is diluted w/40 ml ether, washed w/25 ml water and 2x25 ml 5% NaHCO3,
the org layer is dried and evap'd to yield 40% phenylacetone(134 mg)
FOAF
I attempted to get help with this a few months ago but to no avail...

A little birdie once told me in a PM that reagarding O-Ethyl Hydrogen Phosphonate:
Phosphorous acid is also called Phosphonic acid.
All salts of Phosphorous acid are called Phosphites and are commonly called Phosphonates. They are all one in the same.
O-Ethyl Hydrogen Phosphonate fungicide:
Mix about 100 grams of the phosphite in 100ml of HCl acid and VERY SLOWLY heat it, you dont want to ever see it boil or bubble. Heat it as high as you can without boiling. After 1/4 of the solution has evaporated it should be ready for use.
Someone also told me this also works for Sodium and Potassium Phosphite but the ratios are slightly different ( 90 grams, 100 ml )
halfkast, does this make sense to you? I'm going to attempt to read your post again and fully understand it someday but the picture is slowly getting less fuzzy...
Three months ago I attempted to do this and then decided not to try it after combining the 30%HCL and the O-Ethyl Phosphonate powder in a mason jar. It now sits in the dark in the mason jar wrapped in a towel in a tuperware container. At this point, expert advice would be much appreciated as to the viability of this endeavor at this point in time and/or whether this should instead be disposed of properly post haste.

I didn't notice at first that it was off topic, as it was discussed above in the three posts listed below. I simply wanted to clarify the procedure when I saw it being discussed.
