Abstract
Chlorine-containing gases which may be formed in containers of solid chloroisocyanurates such as trichloroisocyanuric acid are adsorbed and decomposed by a gas scavenging agent consisting essentially of silica gel, an alkali metal bicarbonate, and carbon. The gas scavenger is preferably enclosed in a gas permeable spun-bonded polyolefin envelope. The scavenging agent adsorbs moisture, absorbs and decomposes nitrogen trichloride, removes chlorine, and neutralizes hydrogen chloride formed. The gas scavenging mixture is physically compatible and readily blended while minimizing dusting during packaging operations.
