A heating apparatus includes an elongated flexible envelope () comprising two sheets (), () that are attached to each other along permanent side seams (), () and along a permanent bottom seam () and a moisture-activated chemical heater () disposed inside envelope (), wherein envelope () is folded over on itself and secured by temporary side seams (), () and a permanent top seam () to form a continuous moisture barrier surrounding the moisture activated chemical heater () and wherein heater () may be opened for use by removing top seam () and unfolding envelope () by unpeeling temporary seals (), () to provide unfolded envelope (), wherein sheets () and () remain sealed along permanent seams (), () and (), but wherein envelope () now has an open top end ().

A heat-producing agglomerate contains particles of an acidic component selected from acid anhydrides, acid salts, and mixtures thereof, or a basic component selected from bases, basic anhydrides, basic salts, and mixtures thereof, or a mixture of such acidic and basic components. The heat producing agglomerate provides high heat output at a controllable rate of heat generation, minimizes safety and environmental risks, and is useful as a heat-producing component in self-heating packaging.

An improved method for making polyphosphoric acid from phosphoric acid includes the steps of introducing a first phosphoric acid feed stream into the top end of a packed column, introducing a second phosphoric acid feed stream into a stream of hot air to form a stream of hot air and acid, introducing the stream of hot air and acid into the bottom end of the column, and polymerizing phosphoric acid of the first and second phosphoric acid feed streams to make polyphosphoric acid. By-product phosphoric acids containing organic contaminants may be substituted for all or part of the phosphoric acid stream being introduced into the bottom end of the column to allow recovery of the phosphorus values of the by-product phosphoric acids.
