Formula：CH3OH3
Methanol Standard：GB338-2004
Application：
Methanol is a basic chemical building block for other products such as acetic acid and formaldehyde. It is used in numerous applications including plastics, paints, glues and pharmaceuticals. Methanol is also being used increasingly in new applications, such as waste water denitrification, biodiesel, gasoline blending and fuel cells. One of the main energy applications is to produce dimethyl ether (DME) as substitute for diesel used as fuel in household and industry.
