发明名称 CARBAMIDE NITRATE-BASED COMPOSITION AND METHOD FOR PRODUCTION THEREOF
摘要 FIELD: chemistry.SUBSTANCE: besides carbamide nitrate, the composition contains not more than 4% moisture and up to 1% phosphorus-containing component (with respect to orthophosphoric acid). The phosphorus-containing component used is phosphorus compounds, such as orthophosphoric acid and substituted derivatives thereof, for example oxyethylidene diphosphonic acid, nitrilotrimethylphosphonic acid, including stoichiometrically balanced in a composition in form of a salt, particularly in form of carbamide salts. A method of producing the composition is also disclosed.EFFECT: invention broadens the range of chemical agents for removing carbonate deposits, scales, corrosion products and other products.4 cl, 3 ex
