I-White Crystal Powder Cesium Chloride CAS 7647-17-8 Iyathengiswa

I-Cesium chloride iyisivimbeli sesiteshi se-potassium.I-Cesium chloride ivimbela ukwehla kokuthuthwa kwe-sodium ion okukhiqizwa yi-alloxan.I-Cesium chloride yenze i-arrhythmias, kuhlanganise ne-pointy torsion ventricular tachycardia kumamodeli ezilwane.

1. Chaza i-cesium carbonate emanzini amancane.Engeza i-hydrochloric acid enobuningi obuhlobene obungu-1.18 kancane ngaphansi kokunyakaziswa okuqhubekayo nokusabela kokushisa:

I-Cs2CO3+ 2 HCl → 2 CsCl + 2 H2O + CO2

Uma i-pH=3, engeza i-cesium hydroxide esixazululo ngemva kwamathumba isigamu sehora ukuze i-pH ingabi hlangothi.I-Filtrate kufanele ihlungwe, ihwamuke futhi igxilwe emvuleni yenani elikhulu lekristalu, ipholiswe ekamelweni lokushisa, utshwala bomama buzohlukaniswa, buhlanzwe futhi bomiswe ku-100 C, futhi umkhiqizo uzoqedwa.

2. I-cesium chloride ingatholakala ngokuncibilikisa i-cesium carbonate ku-hydrochloric acid bese ugxilisa isisombululo.I-cesium chloride enobumsulwa obungu-99.5% ivamise ukutholakala futhi ingasetshenziswa ngqo.I-cesium chloride engahlanzekile ngokwanele ingase icwengwe ngezindlela ezilandelayo.

Chaza u-15g we-cesium chloride emanzini angu-100mL ngemva kokushisisa.I-24.2g mercury chloride yayiyi-stoichiometric incibilike ku-25mL 4mol hydrochloric acid.Engeza isixazululo se-HgCl2/HCl esixazululweni esingenhla ngenkathi kushisa, gudluza futhi usihlanganise, bese usipholisa ukuze senze i-CsHgCl3 icwebezele.Ngemuva kokumunca nokuhlunga, qoqa i-crystallization, ulahle utshwala bukamama.Chaza amakristalu emanzini ashisayo angu-120mL bese uwapholisa futhi.Ngenxa yalesi sizathu, i-recrystallization iphindaphindiwe izikhathi ezingu-2-3, futhi insimbi ye-alkali ingancishiswa ibe ngaphansi kuka-0.01%.Ekugcineni, icrystallization incibilika emanzini ashisayo, futhi igesi ye-H2S iyajovwa ukuze igcwale isisombululo.Bese kuba nemvula ye-HgS, i-HgS iyahlungwa, i-filtrate iyaqoqwa, futhi isihlungi siyahwamuka ukuze some ukuze kutholwe i-cesium chloride emsulwa.
