Formaldehyde Description
Formaldehyde is a colorless, flammable gas with a distinctive pungent odor. It is the simplest aldehyde, which is a class of organic compounds with the carbonyl group bonded to at least one hydrogen atom. Formaldehyde was described by August Wilhelm von Hoff mann (1818-1892) in 1867 after the Russian Aleksandr Butlerov (1828-1886) had inadvertently synthesized it in 1857. Formaldehyde readily dissolves in water to produce a solution called formalin, which is commonly marketed as a 37% solution.
Formaldehyde Chemical Properties
Formaldehyde is colorless gas with a very distinct, pungent odor. It is highly soluble in water and in a variety of organic solvents. It has the potential to react explosively with peroxides and nitrogen oxide.
Formalin, the aqueous form of formaldehyde, is a colorless liquid with a very distinct, pungent odor. It is incompatible and may react with strong oxidizers, alkalis,and acids. The liquid has a variable molecular weight, which is dependent on the specific aqueous formulation.
Formaldehyde Definition
Formalin: a colourless solution of methanal (formaldehyde) in waterwith methanol as a stabilizer; r.d.1.075-1.085. When kept at temperaturesbelow 25°C a white polymer ofmethanal separates out. It is used asa disinfectant and preservative forbiological specimens.
Formaldehyde Uses
Formaldehyde (methyl aldehyde, methylene oxide) is a ubiquitous compound found endogenously in the body and environment. It is a colorless, flammable gas with a distinct, pungent odor and is most commonly available in aqueous solutions under the name formalin (37% formaldehyde in water). Formaldehyde has been used as a disinfectant, an embalming agent, and in industry as a precursor in the fabrication of complex compounds. Since scientific research has identified links between formaldehyde and adverse health effects, precautions and protections must be considered during use.
