STUDY OF THE PROCESS OF OBTAINING A NEW COMPLEX-ACTING DEFOLIANT
Abstract
Scientific principles of the technology for obtaining magnesium and potassium chlorates formed during the interaction of chloride and nitrate of magnesium and potassium with sodium chlorates have been developed. The dependence of the ratio of the secondary mother solution of sodium chlorate (BMS:NaCIO3) and the degree of the evaporation process on analytical indicators has been established.Optimal technological parameters for obtaining concentrated solid magnesium chlorate defoliant have been established. Standards for the technological mode of production and basic technological schemes for their obtaining have been developed.
