METHANOL

 Price : please contact

Methanol is primarily converted to formaldehyde, which is widely used in many area, especially polymers. The conversion entails oxidation:

2 CH3OH + O2 → 2 CH2O + 2 H2O
Acetic acid is produced from methanol.

Methanol and isobutene are combined to give methyl tert-butyl ether (MTBE). MTBE is a major octane booster in gasoline.
