This invention belongs to the field of methoxyamine hydrochloride preparation technology and discloses a method for separating methoxyamine hydrochloride and ammonium chloride. The method involves cooling a mixed solution containing ammonium chloride and methoxyamine hydrochloride to selectively crystallize out ammonium chloride, which is then separated to obtain ammonium chloride crystals and a mother liquor enriched with methoxyamine hydrochloride. The mother liquor is then concentrated or dissolved by heating, followed by ultra-low temperature crystallization, separation, and drying to obtain methoxyamine hydrochloride crystals. This invention uses ultra-low temperature segmented crystallization to selectively precipitate ammonium chloride, resulting in methoxyamine hydrochloride crystals with a purity ≥99.9% and ammonium chloride crystals with a purity ≥98%.

This invention discloses a method for producing feed-grade granular high water-soluble phosphorus MDCP, comprising the following steps: 1) mixing phosphoric acid with a portion of calcium carbonate emulsion; 2) the premixed slurry entering a stirred tank reactor for deep reaction neutralization; 3) the reaction slurry being fed into a second tank reactor for secondary neutralization reaction; 4) the secondary neutralization reaction being stirred and granulated to generate granular semi-finished product; 5) drying to obtain the material; 6) the dried material being screened. This invention premixes purified phosphoric acid with a portion of calcium carbonate emulsion and then fully stirs and reacts it in a reaction tank to generate a large amount of high water-soluble calcium dihydrogen phosphate (MCP) slurry. The slurry forms a mixture with the remaining unreacted portion of phosphoric acid, which then undergoes a secondary reaction with the remaining calcium carbonate emulsion to generate dicalcium phosphate (MDCP) slurry. After granulation, drying, screening, and cooling, a qualified granular MDCP product with high water-soluble phosphorus content is obtained.
