her (MTBE) is an organic compound with the chemical formula C5H12O, CAS number , and a molecular weight of 88.148. It is a colorless and transparent liquid with an ether-like odor, a density of 0.74 g/cm³, a boiling point of 55.2°C, and a flash point of -10°C. It is slightly soluble in water and easily soluble in ethanol and . It is an excellent high-octane additive and antiknock agent.
MTBE is mainly used as a additive, with excellent anti-knock properties, which increases octane rating and can also be cracked to produce e. It has good miscibility with , low water absorption, is environmentally friendly, and can be used as an analytical solvent and extraction agent. In chromatography, especially in high-performance liquid chromatography, it is used as an eluent and forms azeotropes with some polar solvents such as water, and ethanol. her also has mild anesthetic effects.

1.Excellent Octane-Enhancing Performance: High octane number (RON 118, MON 101), effectively improves gasoline anti-knock performance, allowing the production of lead-free, high-octane gasoline that meets environmental standards.
2.Low Vapor Pressure & Good Combustion Stability: Moderate volatility reduces gasoline evaporation loss and vapor lock risks, ensuring stable engine operation under various conditions.
3.Strong Solubility & Compatibility: Compatible with most organic solvents and gasoline components, dissolves well in hydrocarbons, alcohols, and ethers, with good miscibility with gasoline.
4.Low Toxicity & Environmental Friendliness: Compared to lead-based additives, it significantly reduces toxic emissions and does not contain heavy metals, making it more environmentally compliant.
5.High Purity & Stable Quality: Strict production control ensures low impurity content, preventing adverse effects on engine parts such as corrosion or rubber swelling.
