c.i.77964 - Preparation Method
Open Data Verified Data
- zinc oxide method: dilute 15% phosphoric acid solution is added into the reactor, and zinc oxide slurry with a concentration of about 20% is slowly added under stirring to react to form zinc phosphate, and the temperature is kept below 30 °c, zinc phosphate dihydrate seeds were added, heated to 80 °c at pH 3, filtered, washed with hot water, pulverized, and dried at 90 °c to obtain a finished zinc phosphate dihydrate product.
- double decomposition method: the trisodium phosphate solution is added into the reactor, the zinc sulfate solution is slowly added under stirring, and the double decomposition reaction is carried out at 70~80 ℃. After complete reaction, the reaction is filtered, the sulfate ions were removed by rinsing with water, and then pulverized and dried at 1 20 ° C. To obtain a finished zinc phosphate dihydrate.

c.i.77964 - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Brief introduction | the natural mineral of zinc phosphate is called "by-phosphate zinc ore", and there are two kinds of α-type and β-type. Its use: phenolic, epoxy, alkyd coating base material, pigment, chlorinated rubber and flame retardant organic polymer materials, as a chemical reagent, medicine used as a preservative, astringent and dental adhesive powder, etc. |
| preparation | zinc phosphate is insoluble in water or ethanol and readily soluble in dilute acid, ammonia and ammonium salt solutions. Zinc phosphate can be obtained by the reaction of a phosphoric acid solution with zinc oxide, or by the reaction of trisodium phosphate with zinc sulfate. |
| Application | used as the base material of alkyd, phenolic, epoxy resin and other coatings, used in the production of non-toxic anti-rust pigments and water-soluble coatings, also used as chlorinated rubber, polymer flame retardant used as analytical reagent used as alkyd, phenolic, epoxy resin and other types of coatings base material, also used in the production of non-toxic anti-rust pigments and water-soluble coatings. Also used for chlorinated rubber, flame retardant synthetic polymer materials. used as pharmaceutical, dental adhesives, also used in anti-rust paint, phosphor, etc. |
| production method | zinc oxide method Diluted 15% phosphoric acid solution was added to the reactor, zinc phosphate is formed by slowly adding Zinc Oxide slurry with a concentration of about 20% under stirring, and the temperature is kept below 30 ℃. Zinc phosphate dihydrate seeds are added and heated to 80 ℃ under the condition of pH value of 3, after filtration, washing with hot water, pulverization and drying at 90 ° C., a finished zinc phosphate dihydrate was obtained. Its 2H3PO4 + 3ZnO → Zn3(PO4)2? 2H2O + H2O double decomposition method the trisodium phosphate solution was added into the reactor, and the zinc sulfate solution was slowly added under stirring, and the double decomposition reaction was carried out at 70~80 ℃, the sulfate ions were removed by rinsing with water, and then pulverized and dried at 120 ° C. To obtain a finished zinc phosphate dihydrate. 3ZnSO4+2Na3P04 → Zn3(PO4)2+3Na2SO4 |
