Use
Methanol has numerous uses. Its main use is in the production of formaldehyde, whichconsumes approximately 40% of methanol supplies. Methanolis a common organic solvent found in many products including deicers (windshield wiperfl uid), antifreezes, correction fl uid, fuel additives, paints, and other coatings. A number ofindustrial chemicals use methanol in their production. Among these are methyl methacrylateand dimethyl terephthalate. Methanol is used to convert methylacrylamide sulfate to methylmethacrylate and ammonium hydrogen sulfate (NH4HSO4):Methanol is used in making the ester dimethyl terephthalate from mixtures ofxylene of toluene. Dimethyl terephthalate is used in the manufacture of polyesters and plastics.
