| titleOfInvention | METHOD FOR PRODUCING Manganese Benzoate (II) |
| abstract | A method of producing manganese (II) benzoate by direct interaction of a metal with a carboxylic acid in the presence of an oxidizing agent, a stimulating additive of iodine and an organic solvent of a liquid phase in a bead mill, characterized in that 0.15-0.50 mol / manganese peroxide is taken as an oxidizing agent / kg, and the molar ratio of metal peroxide (1.5 ÷ 2.2): 1; benzoic acid is taken in an amount of (2.05 ÷ 2.10) · (nMn +), where nMn and are the number of moles of metal and its peroxide in the charge, butyl acetate is used as a solvent for the liquid phase, and 0.02 molecular iodine is used as a solvent -0.05 mol / kg; the process is started and conducted under conditions of vigorous stirring and forced cooling in the temperature range from room temperature to 45-60 ° C until practically quantitative consumption of the metal and its peroxide in the product is achieved, after which the stirring and forced cooling of the reaction mixture are stopped, the reaction mixture is separated from glass beads and filtered, glass beads and reactor elements are washed with a solvent of a liquid phase, which subsequently goes to wash the filter cake, the resulting filtrate is cooled to 7 -10 ° C and kept at this temperature for 2-2.5 hours to complete crystallization of the product, the resulting suspension is filtered, the resulting product precipitates are sent separately for purification by recrystallization, and the filtrate is returned to the repeated process. |
