Procedure: A preparation of manganese propionate is made by combining 114.95 grams of dry manganese carbonate, 300.30 grams of dry acetic acid, and 40.01 grams of sodium hydroxide. The mixture is heated to reflux with constant stirring. Water with some acetic acid is removed by fractional distillation. Heat is increased until the water and about 80 percent of the acetic acid liquid has been removed. Carbon dioxide is released through a vented condenser. The resulting composition of manganese acetate and sodium acetate in residual acetic acid is poured into a flat metal pan and placed in a freezer until cool. After cooling, the solution solidifies into a pink "glass". The "glass" is ground releasing the acetic acid. A white to slightly pink powder is collected containing manganese acetate and sodium acetate.

Procedure: A mixed solution of 1 mole of manganese acetate, ethanol, and water was prepared. This mixed solution and Ketjen Black (KB) were introduced into a rotary reactor, the inner tube was rotated at a centrifugal force of 66,000 N (kgms−2) for 5 minutes to form a thin film of the reactant on the inner wall of the outer tube, and sheer stress and centrifugal force were applied to the reactant to allow promotion of chemical reaction, yielding KB supporting highly dispersed manganese oxide precursor.

Procedure: 1.86 g of manganese(II) acetate (tetrahydrate) were added in portions to a solution of 21.6 g of N,N'-bis-(2-hydroxybenzoyl)-1,2-diaminoethane, [prepared in accordance with: Y. A. Ibrahim, A. H. M. Elwahy, Synthesis 503-508 (1993)] in 30 ml of ethanol and the mixture was heated at reflux for three hours. After the reaction solution had been cooled, the precipitate was separated off, washed with ethanol and dried; this gave 2.88 g of N,N'-bis-(2-hydroxybenzoyl)-1,2-diaminoethane-manganese complex. [prepared in accordance with: Y the mixture was heated at reflux for three hours After the reaction solution had been cooled the precipitate was separated off washed with ethanol dried

Procedure: A 300 ml stainless steel autoclave was charged with 2.00 g manganese (II) acetate (11.6 mmol), 3.07 g cyclopentadiene monomer (46.5 mmol), 70 ml ether, and 4.0 g TEA (35.1 mmol) pre-mixed with some of the ether. The autoclave was sealed and purged with CO. The carbonylation was carried out at 550 psi total pressure and a temperature of 175° C. for two hours. The cooled reactor was vented and the contents transferred to an Erlenmeyer flask. A solution of 10% HCl was added carefully until the salts dissolved. The organic layer was separated and washed with water, dried (MgSO4), filtered and evaporated leaving a red oil. Pentane (100 ml) was added. Cooling to -78° C. for several hours gave 1.10 g (54%) of cyclopentadienylmanganese tricarbonyl product as yellow crystals, mp 65°-69° C. The autoclave was sealed purged with CO A solution of 10% HCl was added carefully until the salts dissolved The organic layer was separated washed with water dried (MgSO4) filtered evaporated leaving a red oil

Procedure: Neodecanoic acid (300 grams) and manganese (II) acetate (106 grams) were both placed into a reaction vessel equipped with a condenser, Dean-stark trap, thermometer, thermocouple, and a gas inlet. Nitrogen gas was bubbled into the reactants. The reactants were heated to 140° C. and stirred for two hours. Overheads and condensate from the reaction were collected in the trap. A subatmospheric pressure was applied to the reaction vessel and the reactants were stirred for an additional two hours at 140° C. until the reaction was complete. Analysis of the product indicated that the product had a kinematic viscosity of 54.8 cSt at 100° C. and a manganese content of 8.1 percent by weight. both placed into a reaction vessel equipped with a condenser, Dean-stark trap Nitrogen gas was bubbled into the reactants Overheads and condensate from the reaction were collected in the trap the reactants were stirred for an additional two hours at 140° C. until the reaction at 100° C.
