Abstract
A thermogenic system based on exothermic chemical reactions for heating consumer-type products as dispensed from suitable packages. The system includes the redox reactions of hydrogen peroxide as the oxidant and as the reductant compounds of the general oxazolidine formula ##STR1## wherein R and R' may be the same or different and are selected from the group consisting of hydrogen, alkyl of from 1 to 4 carbon atoms, and substituted alkyl such as hydroxyalkyl e.g. hydroxymethyl. The effectiveness of the system can be enhanced by the addition of a catalyst selected from the group consisting of p-toluene sulfonic acid, iron filings, and iron salts of either the ferrous of ferric ions such as sulfates and halides thereof e.g. FeSO.sub.4 and FeCl.sub.3.
