Abstract
A process for producing dichlorine monoxide which includes: feeding an aqueous solution of hypochlorous acid containing at least 20% by weight of HOCl to a reaction vessel; maintaining the temperature of the aqueous solution of hypochlorous acid in the range of from about -10.degree. to about +40.degree. C.; passing an inert gas through the aqueous solution of hypochlorous acid to produce a gaseous mixture comprising dichlorine monoxide, chlorine and inert gas; an contacting the gaseous mixture with dry ice to provide a solid phase of dry ice and dichlorine monoxide.

A process for producing dichlorine monoxide which comprises:
- (a) feeding an aqueous solution of hypochlorous acid containing at least 20% by weight of HOCl to a reaction vessel,
- (b) maintaining the temperature of the aqueous solution of hypochlorous acid in the range of from about -10.degree. to about +40.degree. C.,
- (c) passing an inert gas through the aqueous solution of hypochlorous acid to produce a gaseous mixture comprising dichlorine monoxide, chlorine and inert gas, and
- (d) contacting the gaseous mixture with dry ice to form a stable solid phase with the dry ice.
A composition comprised of a mixture of dry ice and liquid dichlorine monoxide at a temperature below about -20.degree. C. containing an amount of dry ice effective to provide a matrix for storing and transporting said liquid dichlorine monoxide.
