Antimony glycol

Antimony glycol

Antimony ingot is a silvery white, brittle metal material, mainly used in the production of flame retardants, alloy materials, semiconductor components and chemical catalysts. Antimony has excellent corrosion resistance and oxidation resistance, and is widely used in electronics, chemical industry, military industry and other fields.

Process

• Raw Materials: The production of ethylene glycol antimony uses high-purity antimony oxide (Sb₂O₃) and ethylene glycol as raw materials.
• Reaction: Antimony oxide and ethylene glycol are placed in a reaction vessel, where they are stirred and reacted to form ethylene glycol antimony.
• Collection: After the reaction, hot filtration is performed to remove unreacted solid impurities. Activated carbon (5–15 kg per ton of antimony trioxide) is then added to adsorb impurities, followed by stirring under constant temperature and subsequent filtration. The crude product is recrystallized using an ethylene glycol or ethanol solution to improve purity. Finally, drying is carried out at 60–150°C under a vacuum of 1.3–21.3 kPa for 4–12 hours to remove residual moisture.
