Tert-Butyl Methyl Ether Cas 1634-04-4

$1.00K - $1.50K
MOQ: 1  Metric Tonnes
Sample Available
 
Methyl tert-butyl ether (MTBE) is a colorless, transparent, low-viscosity, volatile liquid with a distinctive odor and an oxygen content of 18.2%.

lts vapor is heavier than air. Diffuses along the ground and burns when co-existing with strong oxidants.

The main use of methyl tert-butyl ether is as an organic solvent and can also be used as a gasoline additive to make it more antiknock.



Application

ethyl tert-butyl ether (MTBE) is mainly used as gasoline additive, has excellent knock resistance, improves octane number, and can also be cracked to produce isobutene has good miscibility with gasoline, less water absorption, no pollution to the environment, can be improved as an analytical solvent, extractant, in chromatography especially high pressure liquid chromatography as a removal agent, and some polar solvents such as water, methanol, ethanol and other azeotrope formation. Mtbe also has a mild narcotic effect.
