tert-Butyl methyl ether（MTBE）

Name: tert-Butyl methyl ether（MTBE）
SKU: 0

Methyl tert-Butyl Ether (MTBE), with the chemical formula C₅H₁₂O, is an important ether compound. It appears as a colorless transparent liquid with a characteristic terpene-like odor. It features high volatility, low boiling point and high octane number, being slightly soluble in water but miscible with most organic solvents. MTBE is primarily used as a gasoline additive to enhance octane rating, and also has important applications in chemical and pharmaceutical industries.
