Good Evening!
At present I am synthesizing some manganese doped nanoparticles. For that I am in need of MnCl3, but it is not available commercially.
Will anyone can help me to synthesis MnCl3.
I have some formula options.
2MnO2+ 8HCl = 2MnCl3+4H2O+Cl2, is it possible to get manganese trichloride using this way.
If not.
KMnO4 + 8HCl = KCl+ MnCl3+4H2O+2Cl2
which one will works.
In the second chemical formula, i want to know how can we get MnCl3 alone as resultant product.
Calculate the change in the standard Gibbs energy for your reactions. If it is negative, then you can get MnCl3 at 25 0C.
In addition, obtain the oxide Mn2O3 by decomposition with t of the oxide MnO2.
Then try to get your salt by the interaction of Mn2O3 powder with gas HCl. You will not get MnCl3 with hydrochloric acid.
Best regards.
About (unstable) manganic salts; you may want to check:

Try to understand, MnCl3 is unstable and so you can not keep it as it will release chlorine and will form Mn(II)chloride. For your work follow in this way: Take Mn(II)Cl2 and dissolved it in water and add dilute NaOH solution to precipitate Mn(OH)2 and this will look fleshy white in color. You can decant the extra liquid and stir this muddy precipitate with a glass rod in air. The colour of the precipitate will change to deep brown. Aerial oxygen will oxidize Mn(II) to Mn(III) hydroxide under alkaline solution and thus the precipitate will change to Mn(III)hydroxide. Under very cold condition add concentrated hydrochloric acid ( ice cooled) into this precipitate to dissolve it to create rown unstable solution of Mn(III) chloride. If you only want to use Mn(III) ion better use manganic(III) acetylacetonate , a nice stable salt of Mn(III) which you can keep in bottle for several days .Hope this will help
Thank you so much for your time and consideration Professor. Sabyasachi Sarkar Sir. Your suggestion is very much useful and I will try the same today. Once again Thank you, Sir.
usually you can use Mn2O3 and HCl to get MnCl3, bu MnCl3 is unstable so use Mn(acac)3 . You can prepare Mn(acac)3 from experimental inorganic book.
MnCl3 is very unstable, I think you can use the complex MnCl3(dioxane)2, which can be prepared by published methods: see R. Usón, V. Riera, M. Ciriano, M. Valderrama. "Pentacoordinate neutral manganese (III) complexes". Transition Met. Chem. 1976, 1, 122-126.
