Abstract
1. Способ получения основного ацетата меди (II) путем прямого взаимодействия оксида металла с кислотой в бисерной мельнице в присутствии стимулирующей добавки, отличающийся тем, что процесс проводят в присутствии жидкой фазы, растворителем которой является дистиллированная вода, оксид меди загружают в количестве 1,8-3,3 моль/кг в мольном соотношении с уксусной кислотой (1:1,7)÷(1:2,1), стимулирующую добавку дозируют в количестве 0,05 моль/кг, загрузку проводят в следующей последовательности: стеклянный бисер, растворитель жидкой фазы, уксусная кислота, стимулирующая добавка и оксид меди (II) при массовом соотношении стеклянного бисера и остальной загрузки (1:1)÷(1,5:1), далее включают механическое перемешивание и ведут процесс при непрерывном охлаждении в диапазоне температур 20-45°C до практически полного расходования загруженного оксида меди (II) в соль, после чего перемешивание и охлаждение прекращают, отделяют суспензию реакционной смеси от стеклянного бисера, эту суспензию смешивают с промывной водой с остатками реакционной смеси, оставляют на 1-2,5 ч, фильтруют, осадок продукта тщательно отжимают и направляют на очистку путем перекристаллизации, а фильтрат возвращают на загрузку повторного процесса. ! 2. Способ по п.1, отличающейся тем, что в качестве стимулирующей добавки используют молекулярный йод, иодид или бромид калия, хлорид бария или тиомочевину. 1. The method of producing basic copper (II) acetate by direct interaction of metal oxide with acid in a bead mill in the presence of a stimulating additive, characterized in that the process is carried out in the presence of a liquid phase, the solvent of which is distilled water, copper oxide is charged in an amount of 1.8 -3.3 mol / kg in a molar ratio with acetic acid (1: 1.7) ÷ (1: 2.1), the stimulating additive is dosed in an amount of 0.05 mol / kg, loading is carried out in the following sequence: glass beads, acetic acid solvent the stimulating additive and copper (II) oxide in the mass ratio of glass beads and the rest of the load (1: 1) ÷ (1.5: 1), then they include mechanical stirring and the process is carried out with continuous cooling in the temperature range of 20-45 ° C until the charged copper (II) oxide is almost completely consumed in the salt, after which the stirring and cooling are stopped, the suspension of the reaction mixture is separated from the glass beads, this suspension is mixed with wash water with the remains of the reaction mixture, left for 1-2.5 hours, filtered, carefully sediment the product o squeezed and sent for cleaning by recrystallization, and the filtrate is returned to the loading of the repeated process. ! 2. The method according to claim 1, characterized in that molecular iodine, potassium iodide or bromide, barium chloride or thiourea are used as a stimulating additive.
