About tert-Butyl methyl ether CAS 1634-04-4

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.

Versatility in Industrial Applications

Tert-Butyl methyl ether is widely utilized as a fuel additive to enhance gasoline combustion efficiency and reduce emission levels. In laboratories and chemical manufacturing, it serves as an effective solvent for extraction and purification, thanks to its compatibility with organic compounds and high volatility.

Safe Storage and Transport Guidelines

This ether must be stored in sealed drums or tanks in cool, dry, and well-ventilated locations. Follow regulations outlined by IMDG and IATA codes (Class 3) for shipping, using UN Number 2398 for identification. Strictly avoid sources of ignition and incompatible substances like oxidizing agents and acids to ensure stability and safety.

Environmental and Health Precautions

Handling tert-Butyl methyl ether demands care to minimize risks of water contamination and harmful exposure. Although not classified as poisonous, inhalation or ingestion may be hazardous. Employ proper protective equipment, adhere to local regulations, and prevent environmental release during use or transport to mitigate adverse impacts.

FAQ's of tert-Butyl methyl ether CAS 1634-04-4:

Q: How should tert-Butyl methyl ether be safely stored and handled?
