醋酸锰 四水合物

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A 10 l four-neck round-bottom flask with a stirrer, thermometer and reflux condenser was initially charged with 176.0 g (1.95 mol) of oxalic acid in 4200 ml of water, and the resulting solution was admixed dropwise at room temperature with a solution of 318.6 g (1.30 mol) of manganese(II) acetate tetrahydrate in 2100 ml of water, and stirred for a further 15 min after the addition had ended. Subsequently, the reaction mixture was heated to reflux and stirred for a further 30 min. After cooling to room temperature, the white precipitate was filtered off with suction, washed three times with 200 ml of water each time and dried in a vacuum drying cabinet at room temperature overnight.
