A thermal energy storage system for absorption of heat from a heat source having a temperature above a predetermined temperature and release of heat to a heat sink having a temperature below the predetermined temperature. The system comprises a heat storage mass comprising a condensed state material which changes between the solid and liquid phases at about the predetermined temperature and a compartment for containing the heat storage mass. The compartment includes means providing an area for transfer of heat between a fluid and the material. The material may be an aliphatic diamine corresponding to the general formula

Thermal energy storage system

The concentration of chlorine-containing compounds in a gaseous mixture in contact with a solid chloroisocyanurate can be safely lowered by use of a porous crystalline alumino-silicate having an essentially uniform pore size and a free aperture dimension of at least about 3.5 angstroms, said alumino-silicate being essentially unreactive with the chloroisocyanurate and its hydrolysis and decomposition products.
