Application


  • Green Synthesis of Sodium Cyanide Using Hydrogen Cyanide Extracted under Vacuum from Cassava (Manihot esculenta Crantz) Leaves.: This study presents an innovative green approach to synthesizing sodium cyanide using hydrogen cyanide extracted from cassava leaves. The process involves maceration and vacuum extraction, producing NaCN with potential applications in environmentally friendly chemical synthesis and analytical methods (Monga et al., 2022).
