Methanol

Lore & Background

Industrial production evolved from destructive distillation of wood to synthetic methods. Modern low-pressure methanol production was developed by ICI in the late 1960s using copper catalysts. Methanol has been used as a fuel in German military rockets during World War II (as M-Stoff and in C-Stoff with hydrazine) and as an anti-detonation agent in aircraft engines. It is also found in star-forming regions of space and is used as a marker in astronomy.

Methanol's significance lies in its dual role as a fundamental industrial chemical and a potential alternative fuel. As a precursor to formaldehyde, acetic acid, and MTBE, it underpins the production of polymers, solvents, and gasoline additives. Its use in methanol-to-hydrocarbons and methanol-to-gasoline processes offers pathways to liquid fuels from natural gas. As an energy carrier, methanol is easier to store than hydrogen or natural gas, though its energy density is lower than gasoline. It is biodegradable and has low environmental toxicity, with a short half-life in groundwater. In transportation, methanol can be used in internal combustion engines with minimal modification and significantly reduces emissions of sulfur oxides, nitrogen oxides, and particulate matter when used as a marine fuel. Its detection in interstellar space also makes it a valuable marker for star-forming regions. Despite technical success, interest in methanol as a motor fuel waned in the late 1990s due to rising methanol prices and low gasoline costs, though China continues to use substantial amounts as transportation fuel.
