DESCRIPTION
Paraformaldehyde is a polymerized form of formaldehyde (CH,O) and is a stable white crystalline powder. Irritating odor. Because pure formaldehyde is unstable at ambient conditions, paraformaldehyde is used as a readily-usable form of formaldehyde at use sites. Then,formaldehyde gas is generated during heating. Paraformaldehyde is used for different applications as a source of either gaseousformaldehyde or solution formaldehyde.
