METHOD OF IMPROVING SERVICE PERFORMANCE OF LIQUID UREA AND AMMONIUM NITRATE-BASED FERTILIZER

摘要

FIELD: inorganic fertilizers. SUBSTANCE: liquid nitrogen fertilizer is supplemented with, as anticorrosive inhibitory additive, mixture of ammonium phosphates and alkyl phosphates (mono- and dialkyl phosphate salts), wherein 1 weight part of alkyl phosphates fits 2-3 weight parts of ammonium phosphates on conversion to phosphorus pentoxide. Such ratio is provided by correctly combining two liquid nitrogen fertilizer parties, one being inhibited with ammonium phosphates and the other with alkyl phosphates. EFFECT: improved clearness and transparency, and prevented formation of bottom sediment upon storage in contact with carbon steel. 2 cl
