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).
Conversely, a keto group can combine with water to form the geminal hydroxyl groups. The equilibrium in water solution may be shifted towards either compound. For example, the equilibrium constant for the conversion of acetone (H 3 C) 2 C =O to propane-2,2-diol (H 3 C) 2 C(OH) 2 is about 10 −3, [1] while that of formaldehyde H 2 C =O to ...
Propane-2,2-diol, an example of a geminal diol. A geminal diol has two hydroxyl groups bonded to the same atom. These species arise by hydration of the carbonyl compounds. The hydration is usually unfavorable, but a notable exception is formaldehyde which, in water, exists in equilibrium with methanediol H 2 C(OH) 2
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 Biden administration has officially determined the chemical formaldehyde poses an “unreasonable” risk to human health and should be regulated. The Environmental Protection Agency (EPA ...

The FDA determined that the data presented in a 2022 color additive petition show that this ingredient causes cancer in male laboratory rats exposed to high levels of FD&C Red No. 3 because of a ...
The formaldehyde produced is separated from unreacted methanol and byproducts through absorption in water, using a selective absorber. [3] In the fasil process, formaldehyde is synthesized through the catalytic oxidation of methanol. The primary reactions are partial oxidation of methanol (1), and methanol dehydrogenation (2). [4]
