Grade
- Aqueous solutions: 37, 44, 50% inhibited (with varying percentages of methanol) or stabilized or unstabilized (methanol-free); also available in solution in n-butanol, ethanol, or urea; USP (37% aqueous solution containing methanol).See Paraformaldehyde.
ChemUse
- Urea and melamine resins, polyacetal resins, phenolic resins, ethylene glycol, pentaerythritol, hexamethylenetetramine, fertilizer, disinfectant, biocide, embalming fluids, preservative, reducing agent as in recovery of gold and silver, corrosion inhibitor in oil wells, durable-press treatment of textile fabrics, industrial sterilant, treatment of grain smut, foam insulation, particle board, plywood, a versatile chemical intermediate.
Derivation
- Oxidation of synthetic methanol or low-boiling petroleum gases such as propane and butane. Silver, copper, or iron-molybdenum oxide are the most common catalysts.
Properties
- Clear, water-white, very sltly acid gas or liquid; pungent odor. Pure formaldehyde is not available commercially because of its tendency to polymerize. It is sold as aqueous solns containing from 37 to 50% formaldehyde by weight and varying amounts of methanol. Some alcoholic solns are used industrially, and the physical properties and hazards may be greatly influenced by the solvent. Lel: 7.0%, uel: 73.0%, autoign temp: 806°F, mp: −92°, d: 1.083, bp: −21°, flash p: (37%, methanol-free) 185°F, flash p: (15%, methanol-free) 122°F. Sol in H2O and most org solvs except pet ether.
