Description
до полного удалени всей гигроскопической воды, а оставшийс гор чий маточный рассол примен ют дл растворени мирабилита, в цел х его рафинировани .until all the hygroscopic water is completely removed, and the remaining hot uterine brine is used to dissolve mirabilite, in order to refine it.
2. Прием выполнени способа по п. 1, отличающийс тем, что, в цел х получени чистой глауберовой соли из мирабилита , последний раствор ют в гор чем маточном рассоле, означенном в п. 1, с добавлением воды или маточного рассола, остающегос после выкри-. сталлизовывани глауберовой соли в количествах , необходимых дл получени насыщенного раствора и температуры в 40°, после чего раствор отдел ют от механических примесей и подвергают быстрому охлаждению до 0°, а. получающиес при этом кристаллы глауберовой2. Acceptance of the method according to claim 1, characterized in that, in order to obtain pure Glauber's salt from mirabilite, the latter is dissolved in the hot uterine brine, indicated in paragraph 1, with the addition of water or masterbatch, which remains after cry -. stating the Glauber's salt in quantities necessary to obtain a saturated solution and a temperature of 40 °, after which the solution is separated from mechanical impurities and subjected to rapid cooling to 0 °, as well. the resulting crystals of the Glauber's
