Product Application
Methanol is a key raw material for fine chemicals. Under 3.5 MPa and 180–200°C with catalyst, its carbonylation yields acetic acid and further acetic anhydride. It reacts with syngas to form vinyl acetate; with isobutylene to produce tert-butyl methyl ether. It forms dimethyl oxalate via oxidation and carbonylation, then ethylene glycol by hydrogenation. It reacts with toluene under catalytic oxidation to make phenylethyl alcohol.
