Methanol vs. Methanal: Know the Difference

By Shumaila Saeed || Updated on December 25, 2023

Methanol is a simple alcohol (CH3OH) used as a solvent and fuel, while Methanal, also known as formaldehyde (CH2O), is a pungent gas used in resins and as a preservative.

Methanol vs. Methanal

Key Differences

Methanol, also known as methyl alcohol, is a chemical with the formula CH3OH. It's a light, volatile, colorless, flammable liquid with a distinctive alcoholic odor. In contrast, Methanal, better known as formaldehyde, is a simple aldehyde with the formula CH2O, recognized by its pungent, irritating smell.

Dec 09, 2023

Methanol is primarily used as a solvent, antifreeze, fuel, and as a denaturant for ethanol. It is also used in the production of biodiesel via transesterification reaction. On the other hand, Methanal is widely used in the manufacture of industrial resins, including adhesives used in particleboard, carpets, and insulation materials.

Dec 09, 2023

In terms of health and safety, Methanol is toxic and can cause metabolic acidosis, visual disturbances, and even blindness if ingested. Methanal is also toxic, a known carcinogen, and can cause respiratory distress when inhaled, as well as being irritating to the skin and eyes.

Dec 09, 2023

Methanol is produced on a large scale industrially, primarily from the catalytic hydrogenation of carbon monoxide. In contrast, Methanal is typically produced from the oxidation of methanol, indicating a chemical relationship between the two.

Dec 09, 2023

Methanol finds its applications in the chemical industry as a precursor to other chemicals such as formaldehyde, acetic acid, and certain plastics. Conversely, Methanal is used in the medical field as a tissue fixative and embalming agent, and in household products as a disinfectant and biocide.
