INTERACTIONS OF N-ACETYL ETHANOLAMINE WITH AMMONIUM NITRATE AND UREA

Background. One of the main directions of increasing crop yields is the provision of agriculture with mineral fertilizers, plant growth stimulants and pesticides. Рurpose. The aim is to obtain complex new liquid nitrogen fertilizers with physiological activity based on urea, ammonium nitrate, industrial waste, which contains methyl acetate and monoethanolamine. Methodology To perform the research the following method were used: IR-spectroscopy; viscosity of the solutions via a viscometer of the type VSL, pH – via METTLER TOLEDO FE 20 / FG 2 pH meter, refractive index – via IRF 454 refractometer BM model; solubility and interaction of components – via methods of isomolar series and visual polythermal. The solubility in the NH4NO3 – CH3CONHC2H4OH – H2O system was studied using eight internal sections Originality. The solubility of ammonium nitrate in the system was studied. N-acetyl ethanolamine is water; it is established that the system is of a simple eutonic type without the formation of new chemical compounds. Findings. On the basis of polythermal data, a system solubility diagram was constructed from (56.0°C) to 30.0°C, on which the ice crystallization fields, α-NH4NO3, β-NH4NO3, γ-NH4NO3, CH3CONHC2H4OH, are separated. Highlights: - solubility in a system ammonium nitrate - N-acetyl ethanolamine - water; - the isomolar series method for carbamide – N-acetyl ethanolamine – water.
