physical properties

Formaldehyde (systematic name formaldehyde) is a naturally occurring organic compound with the chemical formula CH2O (H−CHO). It is the simplest aldehyde (R−CHO).

Formaldehyde is more complex than many simple carbon compounds because it takes several different forms. Formaldehyde is a colorless gas with a characteristic pungent odor. After condensation, the gas is converted to various other forms of formaldehyde (with different chemical formulas) that are of more practical value. One derivative is the cyclic trimer paraldehyde (1,3,5-trioxane) with the formula (CH2O)3. There is also a linear polymer called paraformaldehyde. These compounds have similar chemical properties and are often used interchangeably.

When formaldehyde dissolves in water, it also forms a hydrate, methanediol, which has the molecular formula H2C(OH)2. The compound is also in equilibrium with various oligomers (short polymers), depending on concentration and temperature. A saturated aqueous solution with a formaldehyde content of about 40% (volume) or 37% (mass) is called "100% formalin". Small amounts of stabilizers, such as methanol, are usually added to inhibit oxidation and polymerization. Typical commercial grade formalin may contain 10-12% methanol in addition to various metallic impurities. "Formaldehyde" was first used as a generic trademark in 1893, and the previous trade name was "formalin".

application

Products derived from formaldehyde include urea-formaldehyde resins, melamine resins, phenol-formaldehyde resins, acetal plastics, 1,4-butanediol, and methylene diphenyl diisocyanate. The textile industry uses formaldehyde-based resins as finishing agents to make fabrics wrinkle-resistant.

When treated with phenol, urea, or melamine, formaldehyde produces hard thermosetting phenol-formaldehyde, urea-formaldehyde, and melamine resins, respectively. These polymers are commonly used permanent adhesives in plywood and carpet. It is used as a wet-strength resin added to toilet paper products such as facial tissue, napkin, roll towel, etc. They can also be foamed to make insulation, or cast into molded products.

Formaldehyde is also a precursor to polyfunctional alcohols such as pentaerythritol, which is used to make paints and explosives.

Formaldehyde solution can be used as a disinfectant and fungicide.

Formaldehyde is used in the manufacture of animal feed.

Formaldehyde preserves or fixes tissues or cells. Used as a tissue fixative and antiseptic.

Formaldehyde is used in drug testing and photography.
