Methanol, also called methyl alcohol or wood alcohol, is a colorless, water-soluble liquid with a mild alcoholic odor. It freezes at 97.6 C, boils at 64.6 C and has a densityof791kgm 3 at20 C
Methanol is mainly a feedstock for the chemical industry and used for the production of varied chemical products and materials.
Methanol is commonly referred to as wood alcohol because it was first produced as a minor by-product of charcoal manufacturing, by destructive distillation of wood.
Almost 65% of the methanol production is used to obtain formaldehyde (39%), methyl tert-butyl ether (MTBE, 14%) and acetic acid (11%). Methanol is also a starting material for chloromethanes, methylamines, methyl methacrylate (MMA), dimethyl terephthalate, and so on.
These chemical intermediates are then processed to manufacture many products of our daily life, including paints, resins, silicones, adhesives, antifreeze and plastics
Formaldehyde, the largest chemical product derived from methanol, is mainly used to prepare phenol-, urea- and melamine-formaldehyde and polyacetal resins as well as butanediol and methylenebis(4-phenyl isocyanate) (MDI).
MDI foam is, for example, used as insulation in refrigerators, doors and in motor car dashboards and fenders. The formaldehyde resins are then predominantly employed as adhesives in the wood industry in a wide variety of applications, including the manufacture of particle boards, plywood and other wood panels. The market for MTBE, an oxygenated gasoline additive and blending component.
