Abstract
A reagent composition which is chemically inert when solid and is chemica reactive when molten comprises a first substance selected from high molecular weight waxes and polymers and a second substance dissolved, dispersed, or encapsulated in the first substance. The second substance is highly chemically reactive and is selected from strong bases and strong acids. The composition is particularly adapted for use in safety devices automatically activated in response to an increase in the temperature of a chemical system and in processes for automatically discontinuing the operation of or decontaminating the products of a malfunctioning chemical system.
