MTBE (Methyl Tert-Butyl Ether) is an organic compound with the chemical formula C₅H₁₂O, widely used as a fuel additive and solvent in chemical industries. This colorless and volatile liquid helps increase gasoline octane rating and reduces environmental pollutants. Due to its solubility in water, MTBE must be carefully stored and handled.

Features:

• Colorless, volatile, ether-like odor
• Flammable
• Soluble in water and many organic solvents

Applications:

• Fuel additive to improve octane rating and engine performance
• Solvent in chemical industries and extraction processes
• Raw material in the synthesis of other organic compounds
• Limited use in pharmaceutical and laboratory applications

Technical Specifications

• Chemical Formula: C₅H₁₂O
• Molar Mass: 88.15 g/mol
• Density: 0.74 g/cm³ at 20°C
• Boiling Point: 55.2°C
• Melting Point: -109°C
• Color: Colorless
• Odor: Ether-like

Hazards and Safety

• Flammable; keep away from heat and flames
• Skin and eye contact must use protective equipment
• Avoid inhalation of concentrated vapors
• Special precautions are required when in contact with water or contaminated environments

Packaging and Storage

• Metal or durable plastic barrels
• Storage Temperature: 15–25°C, away from direct sunlight
• Keep away from heat and sparks

Industrial Applications

• Oil & Energy Industry: improve gasoline octane and reduce pollutants
• Chemical Industry: solvent and raw material for organic synthesis
• Laboratories: for reactions and extraction of organic compounds

In the 1970s, MTBE was introduced as a replacement for lead-based compounds in gasoline to increase octane rating and reduce environmental lead pollution.

Research in 2022 shows that new technologies using activated carbon nanoparticles can efficiently remove MTBE from contaminated water, minimizing environmental impact. Scientific Source
