Copper Acetate

Kovoc - 7-8-2019 at 10:39

I recently made some copper acetate without thinking about what I'm actually gonna use it for, could someone give me some reactions it's used in. Thanks!!!

It is sometimes used as a catalyst in organic chemistry, but there aren't too many other uses of it as far as I know. It acts like most weak acidic copper compounds do.

Its thermal decomposition is pretty interesting: pyrophoric copper and offgassings which can be condensed or ignited:

You can use it to make copper aspirinate and other copper(II) salts.

Test for reducing sugars.

Copper acetate grows most beautiful crystals I have seen, If you end up not doing anything with it, maybe grow some.

totally agree, completely dark and perfect sharp edges, mesmerizing

Per a recent thread of mine:

but decided to attempt a prep because of this very recent (May 2019) article at https://advances.sciencemag.org/content/5/5/eaav7689 . To quote:

"The higher OH yield in the presence of UV light might be due to a photo-Fenton–like reaction (R4), where Fe(III) and organic ligands, such as acetate, which is a product of the initial Fenton-like reaction (R3), form a complex leading to the reduction of Fe and the formation of an organic radical that will form OH.

Fe(III)+CH3C(O)O−+hυ→Fe(II)+CH3C(O)O→OH radical formation (R4) "

The above implies to me that UV light activated Ferric acetate may be of use as a source of photo induced hydroxyl radical creation and as a path to recycling ferric to ferrous in a photo-fenton reaction.

Now, this is not unique, iron oxalate, a case in point, but if one has a good path to the basic iron acetate, that many be of interest to some.

The ferric acetate is recently cited because it apparently naturally occurs in clouds (authors fields include Atmospheric and Environmental Sciences)!

I will not be surprised on a similar property for copper acetate (as Cu like Fe, is a transition metal, albeit not found significantly in clouds) relating to a photo-fenton-type reaction, as it is based on copper, and not the classic iron fenton (or photo-fenton) reaction.

Why and how would iron go into the sky?

Per a source 'Characterization of Atmospheric Iron Speciation and Acid Processing at Metropolitan Newark on the US East Coast', by
Guojie Xu and Yuan Gao, in Atmosphere 2017, 8(4), 66; https://doi.org/10.3390/atmos8040066 or https://www.mdpi.com/2073-4433/8/4/66/htm , to quote:

"The natural source of atmospheric Fe is aeolian dust derived from major deserts in Asia, North Africa, South America, and Australia that is transported and deposited to the ocean [2,3,4,5]. Atmospheric Fe may also come from anthropogenic sources, in particular from regions with heavy air pollution in the Northern Hemisphere. Major anthropogenic sources for Fe include agricultural practices [4], biomass burning [6,7] and combustion emissions [8,9,10]. Recent model results suggest that combustion-derived Fe can represent a large portion of soluble Fe fluxes, with the highest values (30%) close to the East Asian continent in the North Pacific [11]."
