- Abstract
- Chemical analysis methods were used to identify the causes for precipitation and fouling with a gray-green deposit of a vessel for the storage of liquid micro fertilizer consisting of ammonium heptamolybdate, potassium chloride, ammonium vanadate, boric acid, chromium trichloride, sodium selenate, and Trilon B as a chelating ligand. The precipitate represented the crystalline 1 : 1 complex of Trilon B with carbamide NaH3L1 ⋅ (H2N)2CO ⋅ Н2О(H4L1 = ethylenediaminetetraacetic acid). The deposit on the vessel bottom and wall was formed upon transformation of the molybdenum complex Na4(MoO3)2L1 ⋅ 8H2O into insoluble coordination polymer in an acid medium. Neutralization of the solution to pH 6–7 and a decrease in the concentration of Trilon B gave a violet micro fertilizer solution that was stable during storage. The molecular structure of the NaH3L1 ⋅ (H2N)2CO ⋅ Н2О crystal was determined.
