Description
- General description: Paraformaldehyde, a polymerization product of formaldehyde, is used in the polycondensation reaction for the synthesis of thermoset polymers. [1]Paraformaldehyde is also referred as polyoxymethylene. It participates in the regioselective reductive coupling reactions of dienes, alkynes and allenes in the presence of ruthenium catalyst.[2] It also participates in the synthesis of esters, via alkoxycarbonylation of alkenes.[3]
- Application: Formaldehyde source to prepare phenol-, urea-, furfuryl alcohol-, resorcinol- and melamine-formaldehyde polymers for use in coatings, wood products, textiles and foundry resins.
- Features and Benefits: Source of methanol-free formaldehyde.Decomposes in hot water to give formaldehyde.
