monosodium phosphate anhydrous--feed grade: we are manufacturer and we have fami-qs certificate
application:widely used in fish and shrimp feed especially young fish and shrimp feed ideal phosphorus source. the 100% water soluble rate of anhydrous sodium dihydrogen phosphate can ensure the full utilization of phosphorus by fish and shrimp aquatic animals, not only reduce the breeding cost, but also reduce the water pollution caused by the loss of phosphorus source in the breeding process, and meet the requirements of environmental protection to a greater extent.
monosodium phosphate anhydrous
chemical formula: nah2po4
molecular weight: 119.98
properties: white powder or white crystal, the melting point is 190 centigrade. it is soluble in water showing acidity. it decompounds sodium pyrophosphate anhydrous at 225-250 centigrade, and becomes sodium metaphosphate at 350-400 centigrade. it is slightly hygroscopic.
standard executed: hg/t 2767-2009 and gb 25564-2010
