# Mixing Oxalic acid and glycerin

I am doing an experiment for a miticide for honey bees. I will be dissolving 600g of 99.6% Oxalic Acid in one liter vegetable Glycerin at 150°F. I have been told it will give off formic acid fumes while mixing and heating, I don't think it will untill it get to the melting temp. of Oxalic acid? Is there any safety concern? Also what would the shelf life of the mixture be?

• 150 °F is about 65 °C, for those who are wondering. – Martin - マーチン May 17 '17 at 7:27
• Martin, how to refer you by Latin based @username in case of need ? Is "Martin" or "Martin -" enough ? – Poutnik Oct 12 at 5:32

• "Formic acid has almost unlimited shelf life if unopened and is protected from heat and light sources." I have read it needs to be stored with a vent because of slow decomposition $\ce{HCOOH -> H2O + CO}$ – Poutnik Oct 12 at 5:36
