Manganese(II) nitrate is the precursor to manganese(II) carbonate (MnCO 3), which is used in fertilizers and as a colourant. The advantage of this method, based on the use of ammonia (NH 3) and carbon dioxide (CO 2) as reaction intermediates, being that the side product ammonium nitrate (NH 4 NO 3) is also useful as a fertilizer.

The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. The suffix -ol appears in the International Union of Pure and Applied Chemistry (IUPAC) chemical name of all substances where the hydroxyl group is the functional group with the ...
Manganese(III)-mediated radical reactions begin with the single-electron oxidation of a carbonyl compound to an α-oxoalkyl radical. Addition to an olefin then occurs, generating adduct radical 2 . The fate of 2 is primarily determined by reaction conditions—in the presence of copper(II) acetate, this intermediate undergoes further oxidation ...
One method starts with natural manganese dioxide and converts it using dinitrogen tetroxide and water to a manganese(II) nitrate solution. Evaporation of the water leaves the crystalline nitrate salt. At temperatures of 400 °C, the salt decomposes, releasing N 2 O 4 and leaving a residue of purified manganese dioxide. [8]
The chemical reaction, in which ethylene (C 2 H 4) is oxidised by potassium permanganate (KMnO 4) to carbon dioxide (CO 2), manganese oxide (MnO 2) and potassium hydroxide (KOH), in the presence of water, is presented as follows: [55] 3 C 2 H 4 + 12 KMnO 4 + 2 H 2 O → 6 CO 2 + 2 H 2 O + 12 MnO 2 + 12 KOH
Organomanganese chemistry is the chemistry of organometallic compounds containing a carbon to manganese chemical bond.In a 2009 review, Cahiez et al. argued that as manganese is cheap and benign (only iron performs better in these aspects), organomanganese compounds have potential as chemical reagents, although currently they are not widely used as such despite extensive research.
Manganese(II) acetate are chemical compounds with the formula Mn(CH 3 CO 2) 2 ·(H 2 O)n where n = 0, 2, 4. These materials are white or pale pink solids.
Excess molten sodamide at 240 °C reduces manganese oxides to nitrides, with the final product dependent on stoichiometry, through the following reaction. 3 Mn 2 O 3 + 9 NaNH 2 → 2 Mn 3 N 2 + 9 NaOH + N 2 + 3 NH 3. The waste sodium hydroxide selectively dissolves in an aqueous ethanol wash. [7] Manganocene ammonolyzes at 700 °C to give Mn 3 ...
