Ammonia → Ammonium glyphosate ammonium oxalate

関与物質

反応手順

35 lb/hr of glyphosate acid wet cake containing approximately 12–13% by weight moisture and 7.3 lb/hr of di-ammonium oxalate are pre-blended and then metered into the mixer at a rate of approximately 42.3 lb/hr. The surfactant is injected into the mixer at a rate of approximately 0.7 lb/hr. Liquid anhydrous ammonia is injected into the mixer at a rate of approximately 2.6 lb/hr. Water is injected into the reactor at a rate of about 2 lb/hr to attain a total moisture content of approximately 20% by weight of all of the components added to the mixer. The ammonia reacts with the glyphosate acid to produce an ammonium glyphosate/di-ammonium oxalate paste. Water vapor is flashed from the paste product at the exit of the mixer. The moisture content of the ammonium glyphosate/di-ammonium oxalate paste is approximately 8–10% by weight. The pH of a 1% solution of the paste in water is approximately pH 4.5.
