Urea ammonium nitrate ( uan) solution, produced by combining urea, nitric acid, and ammonia, is a liquid fertilizer product with a nitrogen content that typically ranges from 28 percent to 32 percent. you can return to your usual activities immediately. molecular weight: 138. fill your cart with color today! urea nitrate can be prepared by reacting urea with nitric acid.

urea ammonium nitrate. the combination of urea and ammonium nitrate has an extremely low critical relative humidity ( 18% at 30 ° c) and can therefore only be used in liquid fertilizers. urea nitrate ( un) has not found use as a legitimate explosive but is commonly used as an improvised explosive. urea nitrate appears to be a flame retardant. the nitrogen combines with other elements, such as carbon, hydrogen and oxygen, to form urea, which is a. most of that urea ( 85% ) ends up as fertilizer, with a. urea, anhydrous ammonia and liquid urea ammonium nitrate ( uan 28 or 32% ) are by far the most common sources of nitrogen fertilizer used in corn production.

2 achievable emission levels for existing plants 27 8. gentle heat, as from a water bath, should be added to bring the urea and nitrate into solution before the hcl is added. may be subject to detonation if allowed to dry out. it is a carbamide ( organic molecule). molecular formula of urea is co ( nh 2) 2. 1 achievable emission levels for new plants 26 8. 1 mmol/ l) is considered normal.

ask your doctor to explain your results. this commodity is typically produced in chemical facilities near agricultural areas and is shipped as a bulk liquid by rail, highway and vessel. urea is a dry nitrogen source that has long been used for fall, winter and spring application, but is quickly becoming the primary choice for. visually both un and nu are white solids that both melt around 160oc.
