Description
Efekt cieplny reakcji prowadzonej w sposób wedlug niniejszego wynalazku, równa sie róznicy efektów cieplnych reakcji (1) i reakcji <3), co dodatkowo zmniejsza niebezpieczenstwo pro¬ wadzenia procesu. Wolny kwas powstaly w wy¬ niku przesuniecia równowagi (3) przez reakcje (1), usuwa sie znanymi sposobami ze srodowiska re- 4 akcyjnego lub zobojetnia sie amoniakiem, celem dalszego prowadzenia procesu. Istota sposobu wytwarzania bromku amonowego wedlug niniej¬ szego wynalazku polega zatem na dzialaniu bromu na wodne roztwory soli amonowych srednich lub slabych kwasów.Przyklad. Do roztworu 75 kg wodoro¬ weglanu amonowego w 120 1 wody wkrapla sie 54 kg bromu, z taka szybkoscia, by temperatura roztworu nie byla wyzsza niz 30°C a zabarwienie jego nie bylo ciemniejsze od koloru slomkowego.Powstale gazy odprowadza sie przez pluczke, wy¬ pelniona czescia roztworu wodoroweglanu amono¬ wego. Z polaczonych roztworów wydziela sie kry¬ staliczny bromek amonowy w znany sposób przez odparowanie, krystalizacje i suszenie.Wydajnosc w przeliczeniu na brom jest stechio- metryczna. Gazy opuszczajace pluczke wprowadza sie do 120 1 wody, zawierajacej 16,5 kg amonia¬ ku. Otrzymany roztwór wykorzystuje sie do na¬ stepnej szarzy, po uzupelnieniu brakujacych ilosci wodoroweglanu amonowego. PLThe thermal effect of the reaction carried out according to the present invention is equal to the difference between the thermal effects of reaction (1) and reaction <3), which further reduces the risk of carrying out the process. The free acid resulting from the displacement of the equilibrium (3) by the reactions (1) is removed from the reaction environment by known methods or neutralized with ammonia for further processing. The essence of the process for producing ammonium bromide according to the present invention therefore consists in the action of bromine on aqueous solutions of the ammonium salts of moderate or weak acids. 54 kg of bromine are added dropwise to a solution of 75 kg of ammonium hydrogen carbonate in 120 liters of water, at such a rate that the temperature of the solution does not exceed 30 ° C and its color is not darker than the straw color. A full portion of the ammonium bicarbonate solution. From the combined solutions, the crystalline ammonium bromide is separated in a manner known per se by evaporation, crystallization and drying. The yield in terms of bromine is stoichiometric. The gases leaving the rinse are introduced into 120 liters of water, containing 16.5 kg of ammonia. The solution obtained is used for smooth graying after making up the missing amounts of ammonium bicarbonate. PL
