Description
Monoethylene Glycol (MEG)
$C_{2}H_{6}O_{2}$ | Simplest Industrial Diol | Purity $\geq 99.8\%$ | Sourced from Shazand and Marun Petrochemicals | MizanPetroGas
Product Introduction
Monoethylene Glycol, commonly known in the industry as Ethylene Glycol, 1,2-Ethanediol, or simply MEG, is the simplest and most widely used member of the glycols (aliphatic diols) family with the chemical formula $C_{2}H_{6}O_{2}$. This essential organic compound is produced by the hydrolysis reaction of ethylene oxide (EO) with water and remains stable at room temperature as a clear, colorless, odorless, and relatively sweet-tasting liquid.
MEG is one of the largest-volume petrochemical products in global trade, serving as the backbone of the supply chain for numerous downstream industries including polyester fibers, PET bottles, antifreezes, and industrial coolants. The two adjacent hydroxyl groups (-OH) in its small and symmetric structure provide exceptional reactivity for condensation polymerization and ester synthesis. Furthermore, complete miscibility with water in all proportions, extremely low volatility, and a broad liquid state range (from ~ -13°C to 197°C) make MEG an unrivaled, versatile, and strategic raw material across global chemical industries.
MizanPetroGas Company supplies Monoethylene Glycol with a guaranteed minimum purity of 99.8 wt %, sourced directly from Shazand Petrochemical (Arak) and Marun Petrochemical — the two primary hubs of MEG production in Iran — available in bulk, new 220-liter drums, IBCs, and flexitanks.

Pricing and Purchasing Monoethylene Glycol (MEG)
The price of MEG is a function of global crude oil and naphtha prices (feedstock for ethylene crackers), ethylene oxide (EO) rates, global supply and demand for polyester and PET, ocean freight costs, and exchange rate fluctuations. With domestic production from both Shazand and Marun petrochemical complexes, direct and bulk purchasing of MEG from MizanPetroGas provides highly competitive prices for industrial consumers through intermediary elimination and flexible logistics (bulk, drums, IBCs, flexitanks). Contact our sales experts to inquire about daily prices, obtain Certificate of Analysis (COA), and plan your supply schedule.
Production Process
Industrial production of MEG is carried out through the direct hydrolysis of ethylene oxide (EO) with excess water. The main reaction proceeds as follows:
C2H4O (EO) + H2O → HO–CH2–CH2–OH (MEG)
The highest yield (~90%) is achieved under acidic or neutral pH conditions and a high water-to-EO molar ratio (~ 20:1). By-products of this process include diethylene glycol (DEG) and triethylene glycol (TEG), which are separated via multi-stage distillation. Precise control over temperature and the water-to-EO ratio is key to achieving $\geq 99.8\%$ purity with minimal residual DEG ($\leq 0.08\%$).
1
Hydrolysis Reaction
Ethylene Oxide + excess water → glycol mixture (MEG + DEG + TEG) in a pressurized tubular reactor
2
Multi-Stage Distillation
Excess water removal in evaporators → pure MEG separation in the main vacuum distillation column
3
Final Refining & Storage
Final polishing to purity $\geq 99.8\%$ → storage in stainless steel tanks → ready for dispatch
Outstanding Physicochemical Properties
Key Physical Properties
- Broad Liquid Range: Freezing point of -12.9°C to boiling point of 197.3°C — versatile performance over a temperature range exceeding 210 degrees
- Low Volatility: Vapor pressure $\leq 0.01\text{ kPa}$ at 20°C — reduced risk of flammable vapors and product loss
- Density 1.113 g/cm³: Heavier than water — easily identifiable and separable in case of leaks
- Low Viscosity (~ 19.8 cP): Excellent fluidity at operational temperatures — facilitating pumping and blending
Chemical & Functional Properties
- High Miscibility: Complete miscibility with water, alcohols, aldehydes, ketones, and esters — forming stable homogeneous solutions
- Strongly Hygroscopic: Strong affinity to absorb water molecules from the surrounding environment — ideal for natural gas dehydration
- Dual OH Reactivity: Ideal monomer for condensation polymerization — producing polyesters and polyurethanes
- Thermal Stability: Resistant to degradation up to high process temperatures — well-suited for polymerization reactors

Safety and Storage
- ⚠️ Ingestion Hazard (H302): Ingesting MEG is highly toxic and can lead to acute kidney failure, metabolic acidosis, coma, and death. Its sweet taste increases accidental ingestion risk — keep strictly out of reach of unauthorized personnel.
- Skin & Eye Contact: Prolonged contact may cause irritation — use chemical-resistant gloves (nitrile/neoprene) and safety goggles.
- Inhalation: MEG vapor at room temperature is generally non-hazardous due to low vapor pressure — adequate mechanical ventilation remains recommended.
- Approved Storage Vessels: Stainless steel (SS304/SS316), aluminum, internally coated/lined drums — avoid plain carbon steel and galvanized containers.
- Storage Conditions: Store in a dry, cool, well-ventilated area — away from strong oxidizers, concentrated acids, and bases — avoid direct sunlight.
- Storage Temperature: 10–40°C — Note: MEG freezes at temperatures below ~ -13°C.
- Spills & Leaks: Prevent entry into soil, drains, and groundwater — absorb with inert media (vermiculite, sand).
- Firefighting: Water fog, alcohol-resistant foam, dry chemical powder, $CO_{2}$.
- First Aid (Ingestion): Rinse mouth with water — do not induce vomiting — seek immediate emergency medical care. Antidote: Ethanol or Fomepizole administered under medical supervision.
