Product Name:Paraformaldehyde
English Name:Paraformaldehyde
CAS No.:30525-89-4
Aliases:Paraform, Polyoxymethylene, Paraformaldehyde polymer
Molecular Formula:(CH₂O)ₙ
Physical Properties:White crystalline powder with a pungent formaldehyde odor. Melting point 163-175°C; density 1.42 g/mL at 25°C; relative vapor density 1.03. Solubility in water is 0.24 g/100cm³ at 20°C; insoluble in ethanol and ether; soluble in caustic soda and caustic potash solutions. It is a linear polymer of formaldehyde with a degree of polymerization typically between 8 and 100.
Uses:It is widely used in automotive, electrical appliance, instrument, agricultural machinery, daily product, and building material sectors to manufacture various structural parts, and serves as an important raw material for polymer materials such as resins, synthetic fibers, and plastics. In organic synthesis, it is used to produce alcohols, acids, esters, and other compounds for the further synthesis of dyes, pesticides, pharmaceuticals, and surfactants. It is also applied in agriculture as an ingredient in insecticides, fungicides, and herbicides, and in medicine for medical polymer materials and drug delivery systems.
