Formaldehyde - A colorless
gas (usually employed as a solution in water) which
possesses a suffocating, pungent odor. It is derived
from the oxidation of methanol or low-boiling petroleum
gases such as methane, ethane, propane, and butane.
It is widely used in the production of phenol formaldehyde
(phenolic), urea formaldehyde (urea), and melamine formaldehyde
(melamine) resins.
