Description
Изобретение относитс к способам получени солей свинца, в частности бромида свинца, которые примен ютс в промышленности неорганического синтеза, а также дл производства лаков, красок, пигментов.The invention relates to methods for producing lead salts, in particular lead bromide, which are used in the industry of inorganic synthesis, as well as for the production of varnishes, paints, pigments.
Цель изобретени - упрощение и интенсификаци процесса, улучшение условий труда.The purpose of the invention is to simplify and intensify the process, improving working conditions.
Оксид свинца обрабатывают раствором бромида аммони в диметилформамиде СЦМФА) при мольном соотношении оксида свинца к бромиду аммони , равном 1 ;(4-5).Lead oxide is treated with a solution of ammonium bromide in dimethylformamide (SCMFA) with a molar ratio of lead oxide to ammonium bromide equal to 1; (4-5).
П р и м е р. В реактор внос т 2,23 г (0,01 М) оксида свинца и 3,92 г (0,04 М) бромида аммони (мольное соотношение 1:4), приливают 50 мл ДМФА и нагревают при 50С и посто нном перемешивании в течение 2 ч (др исчезновени желтой окраски и получени прозрачного раствора). Выход 3,48 г (94%).PRI me R. 2.23 g (0.01 M) of lead oxide and 3.92 g (0.04 M) of ammonium bromide (molar ratio 1: 4) are introduced into the reactor, 50 ml of DMF are poured in and heated at 50 ° C with constant stirring in for 2 hours (other disappearance of the yellow color and obtaining a clear solution). The output of 3.48 g (94%).
Найдено,%: РЬ 54,4; Вг 43,5. Вычислено,%; РЬ 56,46; Вг 43,54.Found,%: Pb 54.4; Br 43.5. Calculated,%; Pb 56.46; Br 43.54.
Примеры по выбору оптимальных условий даны в таблице.Examples of the choice of optimal conditions are given in the table.
Как видно из опытов 1-4, дл получени бромида свинца оптимальное соотношениеAs can be seen from experiments 1-4, for obtaining lead bromide, the optimum ratio
исходных компонентов равно 1:(4-5). При соотношении, меньшем 1:4, снижаетс содержание основного вещества в целевом продукте, а увеличение соотношени больше 1:5 не приводит к получению дополнительного положительного эффекта.The starting components are 1: (4-5). When the ratio is less than 1: 4, the content of the basic substance in the target product decreases, and an increase in the ratio greater than 1: 5 does not result in an additional positive effect.
Из опытов 5-7 следует, что диметилсульфоксид (ДМСО), метанол и ацетонитрил не пригодны дл получени бромида свинца предлагаемым способом, так как в их среде целевой продукт загр знен исходными веществами или побочными продуктами.From experiments 5-7, it follows that dimethyl sulfoxide (DMSO), methanol and acetonitrile are not suitable for producing lead bromide by the proposed method, since in their environment the target product is contaminated with raw materials or by-products.
Как видно из представленных примеров и сравнительного анализа предлагаемого и известного способов, данный способ позвол ет сократить продолжительность процесса от 10 до 2 ч, значительно упростить процесс за счет сокращени количества операций, а кроме того, улучшить услови труда за счет исключени использовани агрессивной бромистоводородной кислоты.As can be seen from the presented examples and comparative analysis of the proposed and known methods, this method allows to shorten the process time from 10 to 2 hours, significantly simplify the process by reducing the number of operations, and also improve working conditions by eliminating the use of aggressive hydrobromic acid.
