Abstract

Chlorid antimonitý vysokej čistoty sa získá dvojstupňovou rafináciou tak, že v prvom stupni sa chlorid antimonitý sedimentačně čistí a v, druhom stupni sa rafinuje niektorou zo známých metod pásmového· tavenia.High purity antimony chloride is obtained two-stage refining so that in the first in step, antimony trichloride is sedimented purifies and in, the second stage is refined one of the known methods of band fusion.

Description

Vynález sa týká rafinácie chloridu antimonitého, ktorý rieši dosiahnutie vysokej čistoty.The invention relates to the refining of antimony trichloride, which solves the achievement of high purity.

V súčasnosti sa pri rafinácii chloridu antimonitého· na vysokú čistotu používá opakovaná destilačná a najmá rektifikačná metoda. Východiskový preparát chloridu antimonitého· sa získává syntézou elektrolytického antimonu a plynného chlóru. Pri týchto metodách sa používajú komplikované skleněné aparatury, kde často dochádza k porušeniu týchto aparatúr a tým aj k znehodnoteniu čištěného chloridu antimonitého koróziou materiálu aparatúry.Recently distillation and the least rectification method are used for refining antimony trichloride to high purity. The starting antimony trichloride preparation is obtained by the synthesis of electrolytic antimony and chlorine gas. In these methods, complicated glass apparatuses are used, where these apparatuses are often damaged and thus the treated antimony trichloride is destroyed by corrosion of the apparatus material.

Vyššie uvedené nedostatky sú odstraněné sposobom podía vynálezu, ktorého podstatou je, že chlorid antimonitý, získaný syntézou elektrolytického antimonu a plynného chlóru sa v prvom stupni rafinácie sedimentačně čistí a v druhom stupni sa rafinuje niektorou zo známých metod pásmového tavenia. Týmto postupom sa získá chlorid antimonitý vysokej čistoty.The aforementioned drawbacks are overcome by the process of the present invention, wherein the antimony trichloride obtained by the synthesis of electrolytic antimony and chlorine gas is sedimented in the first refining step and refined in the second step by one of the known band melting methods. This procedure yields high purity antimony trichloride.
