4011 Exposure Identification of the agentFrom ( iarc , 2006).Chem. Abstr. Serv. Reg. No.: 50-00-0 Chem. Abstr. Name: FormaldehydeIUPAC Systematic Name: MethanalSynonyms: Formaldehyde gas; formic aldehyde; methaldehyde; methyl alde-hyde; methylene oxide; oxomethane; oxymethyleneCOHHCH2 ORelative molecular mass: : Colourless gas with a pungent odourConversion factor: mg/m3 = ppm; calculated from: mg/m3 = (relative molecular ) ppm, assuming standard temperature (25 C) and pressure (103. 5 k Pa).1. 2 UseFormaldehyde is produced worldwide on a large scale by catalytic, vapour-phase oxidation of methanol. Formaldehyde is used mainly in the production of various types of resin. Phenolic, urea, and melamine resins have wide uses as adhesives and binders in the wood-production, pulp-and-paper, and the synthetic vitreous-fibre industries, in the production of plastics and coatings, and in textile finishing. Polyacetal resins are widely used in the production of plas-tics.
