Paraformaldehyde powder, also known as solid formaldehyde, polyformaldehyde, polyformaldehyde, secondary formaldehyde, or polyformaldehyde, is a type of formaldehyde polymer, CAS 30525-89-4, Its chemical formula is usually HO (CH2O) nH, where n represents the degree of polymerization, ranging from 8 to 100. There are also claims that its molecular formula is (CH2O) n. The appearance is usually white or light yellow, existing in the form of powder, granular or flaky solid. It has a pungent odor of formaldehyde, which originates from the formaldehyde gas produced by its slow decomposition or depolymerization. As an important chemical raw material, polyformaldehyde has a wide range of applications in various industrial fields, thanks to its unique physical and chemical properties. It is usually insoluble in organic solvents such as ethanol, ether, acetone, but can be dissolved in dilute acid and dilute alkali solutions. In cold water, the dissolution rate of polyformaldehyde is slower, while it can dissolve faster in hot water. This solubility enables polyformaldehyde to act as a slow-release agent for formaldehyde in certain chemical reactions, regulating the reaction process by controlling its dissolution rate.

In most chemical drug catalogs, polyformaldehyde powder is often described low-key as a "linear polymer of formaldehyde", a stable solid source of formaldehyde. It appears as a white, amorphous powder or sheet with its characteristic pungent odor. However, behind this seemingly simple substance lies a history of chemical discoveries and applications spanning nearly two centuries. Its story runs parallel and extends to the story of formaldehyde itself, witnessing the deepening of chemists' understanding of molecular behavior and the outstanding ability of the industry to translate theory into practice.
The historical roots of polyformaldehyde are deeply rooted in the discovery of formaldehyde. In 1859, young Russian chemist Alexander Mikhailovich Butlerov first isolated and identified a new aldehyde substance during the experiment of calcium formate dry distillation. However, the usual honor goes to Russian chemist August Wilhelm von Hofmann (then working at the Royal College of Chemistry in the UK), whose team conducted more systematic and extensive research on formaldehyde between 1859 and 1867, and finally clarified its chemical formula as HCHO in 1868, giving it the name "Formaldehyde" (formaldehyde), derived from the Latin word "formica" (ant), because ants are an early source of formic acid, which can be considered a reduction product of formic acid.
When Hoffman and his contemporaries studied the properties of formaldehyde aqueous solution (i.e. formalin), a peculiar and troubling phenomenon was quickly noticed: formaldehyde is extremely unstable and tends to undergo a peculiar transformation. Pure formaldehyde gas or concentrated solution will gradually become turbid during storage, especially at low temperatures, and eventually precipitate as a white, flocculent, or powdery solid precipitate. This substance is insoluble in water and can dissociate and release formaldehyde gas again when heated.
For chemists in the 19th century, this phenomenon was both mysterious and tricky. They initially did not understand the essence of this white precipitate. It is considered a "modified" form or an "addition compound" of formaldehyde. This mysterious white solid is exactly what we know today as polyformaldehyde. Its discovery did not stem from purposeful synthesis, but from observation of the instability of formaldehyde itself. It can be said that polyformaldehyde was accidentally encountered by chemists during their attempt to tame formaldehyde.
