To attain this end by evaporating theliquors is out of the question, owing to its preat object of this invention is the production of solidammonium chloride in a cheap manner. The processdepends on the difficult solubility of ammonium chloridein brine. If a saturated solution of ammonium chlorideof 1 0765 sp. gr., which contains 288grms.
