Methyl tert-butyl ether (MTBE), is a kind of organic compounds, chemical formula C5H12O, colorless transparent liquid, insoluble in water, easily soluble in ethanol, ether, is an excellent high octane gasoline additive and antiknock agent. Mainly used as gasoline additive, has excellent knock resistance, improve the octane number, can also be cracked to produce isobutene. It has good miscibility with gasoline, less water absorption, no pollution to the environment, can be improved as an analytical solvent, extraction agent, in chromatography especially high pressure liquid chromatography as a removal agent, and some polar solvents such as water, methanol, ethanol and other azeotrope formation. Methyl tert-butyl ether also has a mild anesthetic effect.
