Chlorine (I) perchlorate is a chemical compound from the group of perchlorates or chlorine oxides .

Extraction and presentation

Chlorine (I) perchlorate can be obtained by reacting cesium perchlorate with chlorofluorosulfate .

{\ displaystyle \ mathrm {CsClO_ {4} + ClOSO_ {2} F \ longrightarrow ClOClO_ {3} + CsSO_ {3} F}}

It is also formed during the photochemical dimerization of chlorine dioxide at low temperatures.

{\ displaystyle \ mathrm {2 \ ClO_ {2} \ longrightarrow ClOClO_ {3}}}

properties

Chlorine (I) perchlorate is a pale yellow liquid that appears almost white in the solid state. It is shock-sensitive and can only be kept for a limited time at room temperature. Even at -45 ° C slow decomposition takes place, whereby in addition to chlorine and oxygen also dichlorine hexoxide formed.
