📘 Product Description:
Monoethylene Glycol (MEG) is a colorless, odorless, and hygroscopic viscous liquid, widely used in various industrial applications as a solvent, coolant, and raw material. It is the primary building block in the production of polyester fibers, resins, antifreeze fluids, heat transfer liquids, and coatings. Its low freezing point and high water solubility make MEG ideal for thermal and moisture-sensitive formulations.
⚗️ Physical & Chemical Properties:
- Appearance: Clear, colorless liquid
- Odor: Slightly sweet
- Density (20 °C): ~1.1132 g/cm³
- Boiling Point: 197.6 °C
- Freezing Point: −13 °C
- Flash Point (Closed Cup): 111 °C
- Water Solubility: Completely miscible
- pH (1% solution): 6.5–8
- Shelf Life: 24 months under proper storage conditions
🧪 Production Process:
MEG is produced via the controlled hydration of ethylene oxide using water. The production steps are:
- Ethylene is oxidized to Ethylene Oxide using a silver catalyst.
- Ethylene Oxide reacts with Water to form Monoethylene Glycol.
- Byproducts such as DEG (Diethylene Glycol) and TEG (Triethylene Glycol) may also form.
🧯 Safety & Handling:
- Hazards: Toxic when ingested or inhaled; may affect kidneys and liver.
- PPE Recommendations: Gloves, goggles, and proper ventilation during handling
- Packaging: 220-liter steel drums, 1000-liter IBC tanks, or ISO tanks
- Transport Regulations: UN No. 3082 | ADR Class 9 – Environmentally Hazardous Substance
