- Paraformaldehyde,
also known as polyoxymethylene, is the condensation product of
formaldehyde with a typical chain length of 8 - 100 units.
- Paraformaldehyde
commonly has a slight odor of formaldehyde due to decomposition.
- Paraformaldehyde is
a poly-acetal.
Paraformaldehyde is a white, solid polymer of
formaldehyde with the pungent, characteristic formaldehyde
odor.
- Paraformaldehyde is
composed of varying molecular weight polymers of polyoxymethylene
glycols.
- Paraformaldehyde is
slightly soluble in alcohols and insoluble in ethers, hydrocarbons and
carbon tetrachloride.
- Paraformaldehyde
solution behaves like the methanol-free formaldehyde solution of the
same concentration.
- Paraformaldehyde
forms slowly in formaldehyde solutions (formaline) as a white
precipitate, especially if stored in the cold.
- Formaline actually
contains very little monomeric formaldehyde most of it forms short
chains of polyformaldehyde.
- A few percent of
methanol is often added as a stabilizer to limit the extent of
polymerization.
Paraformaldehyde can be depolymerized to formaldehyde
gas by dry heating and to formaldehyde solution by water in the presence
of alkali or heat.
- Paraformaldehyde is
flammable as it decomposes in the heat into the flammable gas
formaldehyde.
- As a formaldehyde
releasing agent, Para formaldehyde is a suspected carcinogen.
- The new modification
involves immersion in 10% formalin following impregnation in ammonia cal
silver nitrate, and the use of a low concentration of 4% Para
formaldehyde in the developer.
- Paraformaldehyde is
used as a thermoplastic and is known known as polyoxymethylene
plastic.
Paraformaldehyde is used as fumigant, disinfectant, and
fungicide, and for the preparation of pure formaldehyde.
