A Volatile Compound of Copper [PDF]

Nature, 1947
Korosy1 has recently reported that copper formate decomposes when heated, evolving a small amount of a volatile copper compound. I encountered a similar phenomenon when gently igniting a deposit from a copper rectifying column, the deposit containing cupric acetate.
