Patent ID: 8216972

Claim:
A process for the manufacture of an aqueous fungicide, bactericide and fertilizer solution comprising the following steps: (1) dissolving phosphorous acid in phosphoric acid to form a solution of an acid mixture; (2) reacting the acid mixture of step (1) with an aqueous hydroxide solution selected from the group consisting of: potassium hydroxide, ammonium hydroxide sodium hydroxide, magnesium hydroxide, copper hydroxide, zinc hydroxide, manganese hydroxide, calcium hydroxide or a combination thereof; at a temperature of about 65° C. to about 260° C. in a continuous reactor while maintaining the ratio of mono-valent cations potassium/ammonium/sodium to phosphorus in a molar ratio from about 1:1 to about 2:1, and the ratio of di-valent cations magnesium/copper/zinc/manganese/calcium to phosphorus in a molar ratio from about 0.5:1 to about 1:1 thereby forming a reaction product comprising phosphates, polyphosphates, phosphites, polyphosphites and phosphate phosphite copolymers; and, (3) rapidly cooling the reaction product to between about 35° C. to 65° C.
