| titleOfInvention | Method of purifying gaseous formaldehyde |
| abstract | Gaseous monomeric formaldehyde is purified by contacting with a solid alkali or alkaline-earth metal salt of an acidic ion-exchange resin at between -20 DEG C. and 180 DEG C. Sulphonated polystyrene, polyacrylic resin, polyphenol or carboxylated polyphenols may be used as sodium, potassium, calcium or magnesium salts. The formaldehyde may be obtained by the pyrolysis of commercial paraformaldehyde, and the absorbent may be in a fixed, moving or fluidized bed and may be regenerated by heating under vacuum or stripping with an inert gas. |
