Abstract
A fusion process for the rapid production of a granular metal soap passes a mixture of metal (e.g. zinc) oxide, one or more molten fatty acids and a catalyst through a heated reactor to form molten metallic soap which is then ejected through a spray nozzle in a cooling tower to form a granular soap product. Use of a spiral tubular reactor with a rapid heating coil is disclosed. The reaction is conducted under pressure to maintain water generated by the reaction in the liquid state. Flashing of the reaction water in the cooling tower aids in cooling and formation of fine granules.
