Description
A flammable, colorless gas with a strong, suffocating odor. Formaldehyde was first synthesized in 1859. It occurs naturally in Coal and Wood smoke and as an outdoor Air pollutant in large cities. Formaldehyde is also found in indoor environments evolved items such as new Particle board, freshly laid carpet, Foam, adhesives, Insulation, and new fabrics. Formaldehyde is a powerful reducing agent reacts with many materials on contact. It will corrode metals. Formaldehyde is used as a Disinfectant, Fumigant, embalming fluid, tanning agent, and in durable press textile finishes. It is also used as an ingredient in some polymers, such as urea, phenolic, melamine, and acetal resins. Aqueous solutions containing 37% formaldehyde by weight (40% by volume) are commercially sold as Formalin. Formaldehyde can self-polymerize to form trioxane and Paraformaldehyde.
