Description

Изобретение касаетс  получени  бромистого натри  из муравьинокислого натри  и брома. В предлагаемом способе взаимодействие между бромом и муравьинокиспым натрием ведетс  в присутствии едкого натра.This invention relates to the production of sodium bromide from sodium formic acid and bromine. In the proposed method, the interaction between bromine and formic sodium is conducted in the presence of caustic soda.

Дл  получени  бромистого натри  по предлагаемому способу, который по сн етс  схемой, изображенной на чертеже , окись углерода из генератора / подаетс  под давлением в автоклав 2, куда предварительно из растворител  дл  щелочи 10 насосом подаетс  раствор едкого натра. В полученный раствор НСООМа подаетс  из сборника 7/бром, каковой вступает в реакцию с НСООНа и избыточным NaOH, имеющимс  в реакторе , с образованием МаВг.In order to obtain sodium bromide by the proposed method, which is explained by the scheme shown in the drawing, carbon monoxide from the generator / is fed under pressure into the autoclave 2, where sodium hydroxide solution is fed from the alkali solvent 10. The resulting solution of HCOOM is fed from a collection of 7 / bromine, which reacts with HCOOH and the excess NaOH present in the reactor to form MaBr.

HCOONa + NaOH + Вг ; 2 NaBr + TJ-HsO + COaHCOONa + NaOH + Br; 2 NaBr + TJ-HsO + COa

По окончании реакции полученный раствор NaBr поступает в выпарной аппарат 3 с солеотделителем 4, в каковок по мере удалени  воды скопл етс  кристаллический NaBr. Из солеотделител  4 соль спускаетс  в центрофугу 5, откуда отфугованный продукт поступает в сушилку 6 и после сушки на склад. Маточный же раствор с центрофуги 5 собираетс  в сборник 7, откуда насосом 8 подаетс  снова на выпарку. В случае же желани  получить крупные кристаллы NaBr раствор в выпарном аппарате 3 увариваетс  до определенной концентрации , после чего направл етс  в кристаллизаторы , оттуда на сушку и на склад.Upon completion of the reaction, the resulting NaBr solution enters the evaporation apparatus 3 with a salt separator 4, as crystalline NaBr accumulates as water is removed. From the salt separator 4, the salt is descended into the centrifuge 5, from where the otfugovanny product enters the dryer 6 and, after drying, to the warehouse. The mother liquor from centrifuge 5 is collected in collection 7, from where pump 8 is fed again to the residue. In the case of the desire to obtain large NaBr crystals, the solution in the evaporator 3 is boiled down to a certain concentration, after which it is sent to the crystallizers, from there to drying and to the warehouse.
