White Crystal Powder Cesium Chloride CAS 7647-17-8 Pa malonda

Cesium chloride ndi potaziyamu njira blocker.Cesium chloride imalepheretsa kuchepa kwa kayendedwe ka sodium ion kopangidwa ndi alloxan.Cesium chloride yachititsa arrhythmias, kuphatikizapo pointy torsion ventricular tachycardia mu zinyama.

1. Sungunulani cesium carbonate mu madzi ochepa.Onjezani hydrochloric acid yokhala ndi kachulukidwe kakang'ono ka 1.18 pang'onopang'ono pansi pa kugwedezeka kosalekeza ndi kutentha:

Cs2CO3+ 2 HCl → 2 CsCl + 2 H2O + CO2

Pamene pH = 3, onjezerani cesium hydroxide ku yankho pambuyo pa chithupsa kwa theka la ola kuti pH isalowerere.Filtrate iyenera kusefedwa, kusungunulidwa ndi kukhazikika ku mpweya wochuluka wa kristalo, utakhazikika mpaka kutentha, mowa wa amayi uyenera kupatulidwa, kutsukidwa ndikuwumitsidwa pa 100 C, ndipo mankhwalawo atsirizidwa.

2. Cesium kolorayidi angapezeke mwa Kusungunula cesium carbonate mu hydrochloric acid ndiyeno kuika yankho.Cesium chloride yokhala ndi chiyero cha 99.5% nthawi zambiri imapezeka ndipo ingagwiritsidwe ntchito mwachindunji.Cesium chloride yomwe siili yoyera mokwanira ingathe kuyengedwa ndi njira zotsatirazi.

Sungunulani 15g cesium chloride mu 100mL madzi mukatenthetsa.24.2g mercury chloride anali stoichiometric kusungunuka mu 25mL 4mol hydrochloric acid.Onjezani yankho la HgCl2/HCl ku yankho lomwe lili pamwambapa likutentha, gwedezani ndi kusakaniza, ndikuziziritsa kuti CsHgCl3 imveke bwino.Pambuyo kuyamwa ndi kusefera, sonkhanitsani crystallization, kutaya mayi mowa.Sungunulani makhiristo mu madzi otentha a 120mL ndikuziziritsanso.Pachifukwa ichi, recrystallization imabwerezedwa nthawi 2-3, ndipo zitsulo zamchere zimatha kuchepetsedwa kukhala zosakwana 0,01%.Pomaliza, crystallization imasungunuka m'madzi otentha, ndipo mpweya wa H2S umayikidwa kuti ukhutitse yankho.Kenako mpweya wa HgS umachitika, HgS imasefedwa, kusefera imasonkhanitsidwa, ndipo kusefera kumawuma kuti ziume kuti zipezeke cesium chloride.
