1.Name: Sodium nitrate
Chemical formula: NaNO3
Formula weght:84.99
2.Property:
(1) ordinary sodium nitrate: white little crystals or light yellow
(2) dry powder sodium nitrate: non-caking, showing loose status.
Density:2.257. It is liable to deliquesce, dissolved in water, soluble in liquid ammonia, slightly soluble in ethanol and glycerin, Melting Point:308. While being heated up to about 380 it will decompose and release oxygen and turn into sodium nitrite,as the heating goes on, it will decompose into oxygen, nitrogen and nitrogen oxide. It has strong oxidability and can cause combustion explosion if being mixed with organic substance, sulfur, sodium nitrate etc.
3. Usage:Â it has been wildly used in the glass industry, dye, dynamite, metallurgy, machinery, ceramic etc.

Excellent preservative properitesproperites Sorbic Acid Potassium Sorbate can restrain effectively the activity of mould yeast and aerophile bateria Restrain growth and reproduction of the pernicious micro organism as pseudomonas staphylococcus salmonella action to restrain growth is more powerful than killing Meanwhile it can not restrain useful microoranganim growth ad Anaerobicbearing barilli acidophil therefore to lengthen food store peroid and remain food original flavor The preservative efficiency of sorbic acid Potassium sorbate is 510 times sodium benzoate
High safety Sorbic Acid Potassium Sorbate is one kind of nonsuturated fatty acid compounds It can be absorbed by human body rapidly then decomposed into CO2 and H2Omoreover no remaining in body ADI 025mgkg based on sorbic acid FAOWHO 1994 LD50 4920 mgkglarge mouse by mouth GRASFDA 1823640 1994 Its toxicity only 112 times table salts and 140 times sodium benzoate
Good stability Sorbic Acid Potassium Sorbate is stable in sealed staus will not be decomposed until 270C It will be oxidized into colored ones and absorbing moisture in case exposed in air for a long time
Wide application At the momentSorbic Acid Potassium Sorbate has been used extensively in food drinkvegetables in soy tabacco drugs cosmetics agricultural products forage and other domain Its applicaion should be wide and wide in the world
As acidic preservative Sorbic Acid Potassium Sorbate is also used well in neutral foodph6065 The preservative efficiency of sodium benzoate will decrease clearly and have a bed taste while ph4
