Reactions
Manganese (II) acetate can be formed by reacting acetic acid with either manganese (II,III) oxide or manganese (II) carbonate : Mn3O4 + 2CH3COOH → Mn(CH3COO)2 + Mn2O3+ H2O If manganese (II,III) oxide is used , manganese (III) oxide is produced as a byproduct. If the anhydrous form needs to be produced, manganese (II) nitrate can be reacted with acetic anhydride.
Purification Methods
Crystallise it from water acidified with acetic acid. [Beilstein 2 IV 120.]
Check Digit Verification of cas no
The CAS Registry Mumber 638-38-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 638-38:
(5*6)+(4*3)+(3*8)+(2*3)+(1*8)=80
80 % 10 = 0
So 638-38-0 is a valid CAS Registry Number.

Mn(iv) acetate was generated in acetic acid solutions and characterized by UV-vis spectroscopy, magnetic susceptibility, and chemical reactivity. All of the data are consistent with a mononuclear manganese(iv) species. Oxidation of several substrates was studied in glacial acetic acid (HOAc) and in 95 : 5 HOAc-H2O. The reaction with excess Mn(OAc)2 produces Mn(OAc)3 quantitatively with mixed second-order kinetics, k (25.0 °C) = 110 ± 4 M-1 s-1 in glacial acetic acid, and 149 ± 3 M-1 s-1 in 95% AcOH, ΔH ? = 55.0 ± 1.2 kJ mol-1, ΔS ? = -18.9 ± 4.1 J mol-1 K-1. Sodium bromide is oxidized to bromine with mixed second order kinetics in glacial acetic acid, k = 220 ± 3 M-1 s-1 at 25 °C. In 95% HOAc, saturation kinetics were observed.

A method for modifying ethylenic unsaturation in a triglyceride. One or more unsaturated fatty acyl moieties present in the triglyceride are substituted with a lactone or ketone moiety via a electron donor mediated reaction. The resulting reaction products are useful, for example, as formulations for lubricants, hydraulic fluids, dielectric fluids, and intermediates for polymer synthesis.
