ABSTRACT:
The invention relates to a unique chemical heater formulation for generat heat through the exothermic reduction of cupric chloride by aluminum. The chemical reaction system used in the heater formulation contains a cupric chloride, a wetting agent, water and a polar organic solvent for said cupric chloride which when contacted with aluminum will react to produce temperatures in excess of 100.degree. C for a sustained period of time, with peak temperature reaching the order of 156.degree. C. Optimum results have been achieved with a reaction system consisting essentially of cupric chloride dihydrate, 48.4wt%; polyethylene glycol 1.6 wt%; water 9.7 wt% and ethylene glycol, 40.3wt%.
