Description
Изобретение относитс к технологии получени смешанного гидроксохлорида гидроксида меди - одного из наиболее эффективных фунгицидов контактного действи дл защиты сельскохоз йственных культур от грибковых заболеваний .The invention relates to the technology of producing mixed hydroxochloride of copper hydroxide - one of the most effective contact fungicides for protecting agricultural crops from fungal diseases.
Целью изобретени вл етс уиень- шение расхода гипохлорита натри и снижение количества воды на промывку продукта.The aim of the invention is to reduce the consumption of sodium hypochlorite and reduce the amount of water per product wash.
П р и м е р 1. В стекл нную колонну загружают 10 г металлической меди и заливают 100 мл воды. С помощью насоса раствор, стекающий из колонны, возвращают через буферную емкость на орошение колонны. Одновременно снизу колонны подают электролитический хлпр и кислород воздуха, а затем в циркулирующий раствор подают гипохлорит натри . Температуру циркулирующей смеси поддерживают равной 20 С. По мере ввода щелочного раствора гипохлорита рН раствора постепенно повышаетс и при достижении pff 3,0 в растворе по вл ютс частички смешанного гидроксохлорида гидроксида меди - раствор переходит в суспензию. Суспензию собирают в приемную емкость. Через 4 ч при достижении рН 7 твердый кристаллический продукт отфильтровывают от маточ-. JHOTO раствора. Осадок отмывают от растворимых хлоридов. Расход промывочной воды 4,8 мл на 1 г продукта. Дл получени 100 г целевого продукта расходуетс 320 мл гипохлорита натри , содержащего 100 г/л активного хлора. Осадок смешанного гидроксохлорида гидроксида меди высушивают при 90- 100°С.EXAMPLE 1 10 g of metallic copper was charged into a glass column and 100 ml of water was poured. Using a pump, the solution flowing from the column is returned through the buffer tank to irrigate the column. At the same time, electrolytic chlorofluoride and oxygen of the air are supplied from the bottom of the column, and then sodium hypochlorite is fed into the circulating solution. The temperature of the circulating mixture is maintained at 20 ° C. As the alkaline hypochlorite solution is introduced, the pH of the solution gradually rises, and when pff 3.0 is reached, particles of mixed hydroxochloride copper hydroxide appear in the solution - the solution goes into suspension. The suspension is collected in the receiving tank. After 4 hours at a pH of 7, the solid crystalline product is filtered from the mother liquor. JHOTO solution. The precipitate is washed from soluble chlorides. Wash water consumption 4.8 ml per 1 g of the product. To obtain 100 g of the desired product, 320 ml of sodium hypochlorite containing 100 g / l of active chlorine is consumed. The precipitate of the mixed hydroxochloride copper hydroxide is dried at 90-100 ° C.

Приме р 2. Процесс получени смешанного гидроксохлорида гидроксида меди ведут аналогично примеру 1, но окислитель ввод т до рН 5. ПрТи этом расход гипохлорита натри снижаетс до 160 мл., т.е. в два раза по сравнению с примером 1 за счет увеличени подачи кислорода воздуха в два раза, а количество воды дл отмывки продукта от растворимых хлоридов сни7 жаетс в два раза и составл ет 2,0- 2,4 мл на 1 г целевого продукта.Example 2. The process of obtaining a mixed hydroxyl chloride of copper hydroxide is carried out analogously to example 1, but the oxidizing agent is introduced to pH 5. Then, the consumption of sodium hypochlorite is reduced to 160 ml, i.e. twice as compared with example 1 due to an increase in the supply of oxygen to the air twice, and the amount of water for washing the product from soluble chlorides is halved and is 2.0-2.4 ml per 1 g of the target product.
Количество воздуха, подаваемого на окисление, должно содержать кислорода в 5-10 раз выше стехиометричес- ки необходимого вследствие малой растворимости кислорода в циркулирующем растворе.The amount of air supplied to the oxidation should contain oxygen 5-10 times higher than the stoichiometric required because of the low solubility of oxygen in the circulating solution.
Результаты опытов 4-часового синтеза отражены в таблице.The results of the experiments of the 4-hour synthesis are reflected in the table.
Как видно из экспериментальных данных, при увеличении расхода кислорода воздуха дл получени одного и того же количества продукта требуетс значительно меньший расход гипохлорита натри и меньшее количество воды на промывку продукта от хлоридов. При продувке одним кислородом(опыт 4) резко падает выход продукта.As can be seen from the experimental data, with an increase in the oxygen consumption of the air, to obtain the same amount of product, significantly less sodium hypochlorite consumption and less water are needed to flush the product from the chlorides. When purging with oxygen alone (experiment 4), the yield of the product drops sharply.
Соотношение между гипохлоритом натри и кислородом воздуха равно 1:4,5 и рассчитываетс следующим образом:The ratio between sodium hypochlorite and air oxygen is 1: 4.5 and is calculated as follows:
I Cu+NaClO+Cl2+Ox+5HzO 3CuO- CuClz -5H20+NaCl 74,532463,5I Cu + NaClO + Cl2 + Ox + 5HzO 3CuO- CuClz -5H20 + NaCl 74.532463.5
Выход продукта 100 г (опыт 3). Количество гипохлорита, необходмое дл получени 100 г продукта, рассчитываетс следующим образом: 74,5 - 463,5 х - 100The yield of 100 g (experiment 3). The amount of hypochlorite required to obtain 100 g of product is calculated as follows: 74.5 - 463.5 x - 100
X 1 6,1 Г.X 1 6,1 G.
Количество кислорода, необходим дл получени 100 г конечного продукта:The amount of oxygen required to obtain 100 g of the final product:
32 - 463,532 - 463.5
х - 100 . х 6,9 г.x - 100. x 6.9 g.
Установлено, что дл сохранени выхода продукта избыток кислорода .должен быть в 10 раз выше стехиомеIt has been established that, in order to preserve the yield of the product, an excess of oxygen must be 10 times higher than
рического количества, т.е. 69 г. ithe quantity, i.e. 69 y
Отсюда соотношение гипохлорита натри к кислороду 16,,5.Hence, the ratio of sodium hypochlorite to oxygen is 16,, 5.
В примере 2 указано количество гипохлорита не в г, а в миллилитрах и составл ет 160 мл. Поскольку некондиционньй гипохлорит натри сдержит 100 г/л активного хлора, то 160 мл это 1 6 г.Example 2 shows the amount of hypochlorite not in g, but in milliliters, and is 160 ml. Since non-conditioned sodium hypochlorite will contain 100 g / l of active chlorine, then 160 ml is 1 6 g.

Расход кислорода в примере 2 в два раза выше, чем в примере 1 и сос5 тавл ет 16:69 1:4,5.The oxygen consumption in example 2 is two times higher than in example 1 and is 16:69 1: 4.5.
