  2. Formaldehyde - Wikipedia

    en.wikipedia.org/wiki/Formaldehyde

    Formaldehyde (/ f ɔːr ˈ m æ l d ɪ h aɪ d / ⓘ for-MAL-di-hide, US also / f ə r-/ ⓘ fər-) (systematic name methanal) is an organic compound with the chemical formula CH 2 O and structure H−CHO, more precisely H 2 C=O. The compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde.

  3. Urea-formaldehyde - Wikipedia

    en.wikipedia.org/wiki/Urea-formaldehyde

    Urea-formaldehyde (UF), also known as urea-methanal, so named for its common synthesis pathway and overall structure, [1] is a nontransparent thermosetting resin or polymer. It is produced from urea and formaldehyde. These resins are used in adhesives, plywood, particle board, medium-density fibreboard (MDF), and molded objects.

  4. Aldehyde - Wikipedia

    en.wikipedia.org/wiki/Aldehyde

    Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are a common motif in many ...

  5. Phenol formaldehyde resin - Wikipedia

    en.wikipedia.org/wiki/Phenol_formaldehyde_resin

    Simplfied general structure of a resole. Base-catalysed phenol-formaldehyde resins are made with a formaldehyde to phenol ratio of greater than one (usually around 1.5). These resins are called resoles. Phenol, formaldehyde, water and catalyst are mixed in the desired amount, depending on the resin to be formed, and are then heated.

  6. Formaldehyde releaser - Wikipedia

    en.wikipedia.org/wiki/Formaldehyde_releaser

    3D structure of Formaldehyde. A formaldehyde releaser, formaldehyde donor or formaldehyde-releasing preservative is a chemical compound that slowly releases formaldehyde. Formaldehyde-releasers are added to prevent microbial growth and extend shelf life. [1]

  7. Formaldoxime - Wikipedia

    en.wikipedia.org/wiki/Formaldoxime

    It is the oxime of formaldehyde. A colorless liquid, the pure compound tends to polymerize into a cyclic trimer. Aqueous solutions are stable as is the formaldoxime hydrochloride ([H 2 C=N(−H)(−OH)] + Cl −). It is a reagent in organic synthesis for the conversion of aryl diazonium salts to aryl aldehydes. [1]

  8. Polyoxymethylene - Wikipedia

    en.wikipedia.org/wiki/Polyoxymethylene

    To make polyoxymethylene homopolymer, anhydrous formaldehyde must be generated. The principal method is by reaction of the aqueous formaldehyde with an alcohol to create a hemiformal, dehydration of the hemiformal/water mixture (either by extraction or vacuum distillation) and release of the formaldehyde by heating the hemiformal.

  9. Methanediol - Wikipedia

    en.wikipedia.org/wiki/Methanediol

    Methanediol, also known as formaldehyde monohydrate or methylene glycol, is an organic compound with chemical formula CH 2 (OH) 2. It is the simplest geminal diol . In aqueous solutions it coexists with oligomers (short polymers).
