CAS No.: 1634-04-4
Chemical formula: C5H12O
Melting point: -109οC,
Boiling point: 55.2οC,
specific gravity: 0.74.
Application:
Colorless, transparent, high-octane liquid with ether-like odor. It is an ideal blending component in the production of lead free, high octane and oxygenated gasoline. MTBE is also an important chemical raw material, such as the preparation of high purity isobutylene by splitting. Can also be re-splitting to isobutene as the raw material of rubber and other chemical products.
