APPLICATIONS

Formaldehyde is the simplest aldehyde with the formula HCH=O. It is a gas at room temperature with a pungent smell. It cannot be readily isolated or handled in the pure state because it is extremely reactive. Formaldehyde reversibly polymerizes to its cyclic trimer 1,3,5-trioxane or the linear polymer polyoxymethylene. It is readily oxidized to form formic acid in the air. It is commercially available as an aqueous solution usually 37-50% w/w. Formalin is the solution of formaldehyde in water. Paraformaldehyde is a white crystalline solid formed by polymerization of formaldehyde. Formaldehyde kills most bacteria, and used as a disinfectant and as a preservative and fixative for pathologic specimens. Formaldehyde cross links amino groups. In industry formaldehyde is used in the production of thermoset resins, functional polyols, explosive, hexamine and other chemicals. Examples of formaldehyde-releasing biocides are:

• Imidazolidinyl Urea (CAS RN: 39236-46-9)
• Diazolidinyl Urea (CAS RN: 78491-02-8)
• 1,3-Dimethylol-5,5-dimethylhydantoin (CAS RN: 6440-58-0)
• Bronopol (CAS RN: 52-51-7)
• Tris(hydroxymethyl)nitromethane (CAS RN: 126-11-4)
• Polyethylene glycol sorbitan monolaurate (CAS RN: 9005-64-5)
• Poly(acrylamide, trimethylaminoethyl methacrylate chloride) (CAS RN: 35429-19-7)

Nitroisobutylglycerol releases formaldehyde in aqueous alkaline solution. It is an effective disinfectant or deodorant in household goods field as well as in the industrial fields such as drilling muds, water cycling systems, metalworking fluids and emulsions. It is soluble in water and easily formulated into water-base concentrates.
