METHOD FOR CONTROL OF PRODUCING MONO- AND DIAMMONIUMPHOSPHATE SOLUTIONS

摘要

FIELD: producing liquid complex fertilizers and other mono- and diammonium-phosphate solutions having mass ratio of phosphorous (V) oxide to nitrogen (2.5-5.1): 1. SUBSTANCE: in a sample of analyzed solution density and pH have been determined. With the help of these values mass portions of phosphorous (V) oxide and nitrogen are calculated, equations given in specification being used. Density of solvents are determined preliminary with the help of equations given in specification, mas parts of phosphorous (V) oxide and nitrogen in analyzed solution being once determined with the help of analytic method. EFFECT: improves efficiency of the method. 3 cl
