Study of Solubility of Ca(ClO3)2–[90% C2H5OH + 10% C10H11ClN4]–H2O System

The solubility of components in Ca(ClO3)2–[90% C2H5OH + 10% C10H11ClN4]–H2O system has been studied in the temperature range from –43.6 to +50.0°С by visual polythermic method. Fields of ice, Ca(ClO3)2·6Н2О, Ca(ClO3)2·4Н2О, Ca(ClO3)2·2Н2О, and acetamiprid crystallization have been delimitated on the phase diagram. Change in the physicochemical properties of solutions showing insecticide activity depending on component ratio has been studied. The results of system study indicate the possibility to obtain liquid defoliant showing insecticide activity.
