Description

technical field [0001] The invention belongs to the technical field of phosphorus chemical industry, in particular to a combustion device with automatic phosphorus addition function. Background technique [0002] Phosphorus pentoxide, molecular formula P 2 o 5 , molecular weight 141.98, white monoclinic crystal or powder, density 2.39g / cm 3 , melting point 580-585 ℃, 300 ℃ sublimation. Soluble in water and sulfuric acid, insoluble in acetone and ammonia. It is easy to absorb moisture and deliquesce in the air, and it will burn when in contact with organic matter. Phosphorus pentoxide is a common raw material and reagent in the chemical industry. It is widely used in medicine, coating additives, printing and dyeing additives, antistatic agents, titanate coupling agents, and is the main raw material for phosphorus oxychloride and other chemical products. It is mainly used in the manufacture of high-purity phosphoric acid, as a gas and liquid desiccant, as a dehydrating ag...
