Manganese Hydroxide. Manganese hydroxide [18933-05-6] is a weaMy amphoteric base having low solubihty in water. Mn(OH)2 crystals are reported to be almost pure white and darken on exposure to air. Manganese dihydroxide occurs in nature as the mineral pyrochroite and can also be prepared synthetically by reaction of manganese chloride and potassium hydroxide that is scmpulously free of oxygen. The entire reaction is conducted under reducing conditions (36). 

Dipping solution Dissolve 0.2 g manganese chloride tetrahydrate in 30 ml water and add 30 ml methanol. Mix well and then carefully add 2 ml cone, sulfuric acid dropwise.

These materials are essentially combustion improvers and tend to have fairly simple formulations (e.g., 3% copper chloride, 7% manganese chloride, 90% ammonium chloride). They are designed to change the crystalline structure within the clinker crystal lattice and raise the clinker eutectic point, thus minimizing the formation of noncombustible clinker, residual ash, and other deposits. Feed rates are approxiimately 0.5 to 2.0 lb per bone-dry ton.

Copper-Catalyzed Alkylation of Organomanganese Reagents Preparation of 2,2-Dimethyldecane from tert-Butyl Manganese Chloride. 

Manganese chloride, 98%, was purchased from Aldrich Chemical Company, Inc., or from Janssen Chimica. It must be finely pulverized then dried by heating at 180°-200°C (0.1 mm to 0.01 mm) for 6 hr (for example, in a vacuum oven) prior to use. The anhydrous salt is very hygroscopic and must be protected against moisture (a well-closed bottle is convenient). It can, however, be handled very quickly without any special precaution. 

Manganese-copper-catalyzed conjugate addition of organomagnesium reagents to a,p-enones is a general synthetic method. Table I shows that the reaction can be successfully performed even with enones of low reactivity. 30% Manganese chloride is necessary to obtain good yields. In most cases, however, 0.1% cuprous chloride is sufficient.3... 

Manganese chloride is inexpensive and the work-up is easier with manganese than with copper. This is an advantage, especially for large-scale preparations. 

Manganese chloride (MnClj) is used in the pharmaceutical industry as a dietary supplement and is added to fertilizers.
