  • Acid-base fuels for self heating food containers
    Patent number: 5542418
    Abstract: An exothermic, hydratable fuel mixture for a self-heating food container comprises particles of a base such as lime and an acid such as oxalic acid. When water is added to the mixture, exothermic heat is generated by hydration of the lime and neutralization reaction between the lime and the acid. Mixtures of bases and mixtures of acids can be used to optimize the heating characteristics of the fuel mixture.
