  • Process for the production of overbased manganese salts of organic acids
    Patent number: 4179385
    Abstract: Solutions of overbased manganese salts of organic acids that contain from 20% to 28% by weight of manganese are prepared by(a) carbonating a reaction mixture that contains excess manganous oxide, an organic acid, a promoter, a copromoter, a solvent system, and 0.3% to 0.8% by weight of water, based on the weight of the solvent system, at a temperature in the range of 50.degree. C. to 100.degree. C. at a pressure in the range of 1 atmosphere to 10 atmospheres, thereby forming a solution of overbased manganese salt that contains 2% to 10% by weight of manganese, and(b) heating said solution under subatmospheric pressure to separate a distillate from a residue that is a solution of overbased manganese salt that contains 20% to 28% by weight of manganese.
