Abstract
1. Способ получения двуокиси марганца путем каталитического окисления кислородом воздуха сульфата марганца (II) в водном растворе, содержащем сульфат аммония, в присутствии катализатора и при перемешивании реакционной массы, отличающийся тем, что, с целью повышения содержания основного вещества в продукте и ускорения процесса, раствор подвергают контактированию с газообразным аммиаком и удельным расходом 0,03-0,06 м/ч•кг и процесс ведут при температуре от -5 до 0C.2. Способ по п.1, отличающийся тем, что в качестве катализатора используют аммиакат переходного металла третьего или четвертого периода периодической системы в количестве 3-10% в пересчете на комплексообразующий ион по отношению к содержанию марганца (II) в реакционной смеси.1. A method of producing manganese dioxide by catalytic oxidation by air oxygen of manganese sulfate (II) in an aqueous solution containing ammonium sulfate, in the presence of a catalyst and with stirring of the reaction mass, characterized in that, in order to increase the content of the basic substance in the product and accelerate the process, the solution is contacted with ammonia gas and a specific flow rate of 0.03-0.06 m / h • kg and the process is carried out at a temperature of from -5 to 0C.2. The method according to claim 1, characterized in that the catalyst used is a transition metal ammonia of the third or fourth period of the periodic system in an amount of 3-10% in terms of the complexing ion with respect to the content of manganese (II) in the reaction mixture.
