, is an organic compound, chemical formula C5H12O, colorless transparent liquid, insoluble in water, soluble in ethanol, ether.
- MTBE has a camphor-like odor, colorless and transparent, and can be completely miscible with alcohol, ether, aliphatic hydrocarbon, aromatic hydrocarbon, halogenated solvent at room temperature.
- Like other methyl tertiary alkyl ethers, MTBE has another very important property, namely, it is highly resistant to auto-oxidation and is not easy to form peroxides.
- Methyl tert-butyl ether is currently a replacement for tetraethyl lead.

- Name: Methyl-Tert-Butyl Ether/ MTBE
- CAS: 1634 -04-4
- Chemical formula: C5H12O

Methyl tert-butyl ether (MTBE) Uses
- MTBE In Gasoline: It is mainly used as a gasoline additive and has excellent anti-knock properties.
- Cracking into high-purity isobutylene for the production of MMA and butyl rubber;
- Medical use: MTBE has a mild anesthetic effect in medical application.

- Store in a cool, ventilated warehouse.
- Keep away from fire and heat sources.
- Keep the containersealed Store separately from oxidants, reducing agents, etc. and avoidmixed storage.Use explosion-proof lighting and ventilation facilities.
